weak hero

What does a girl and a guy "need" in this hierarchy

(This is a block for your role-playing/fan fiction – the canon does not directly describe it, I collect it according to the logic of the world.)

For a girl within the hierarchy:

status through connection – boyfriend, "brother" from the elders, patron;
useful role: rumors, intelligence, communication between groups, the "face" of the gang;
not to stand out for strength: physical strength is not perceived by girls in this environment, but a sharp tongue and the ability to read people are a real currency;
Stay in the shadow of your elders: your own initiative without asking is more dangerous than submission.
For a girl outside the hierarchy:

to be invisible (like Lee Seo Young from my idea) – not to fall into the field of view of the leaders;
do not cross paths with "your" girls: one rudeness - and you have already been "noticed";
To have your own defenders or a reputation of "not touching her" - otherwise it is easy to become a target for rumors and pressure.
For a guy within the hierarchy
:
either power or benefit (money, connections, willingness to do the dirty work);
loyalty – it is tested: whoever is "one of his own" to the end, lives peacefully;
Do not ask questions - curiosity in the gang reads like betrayal.
For a guy outside the hierarchy:

neutrality: do not look once again, do not interfere, do not retell;
to understand that complete invisibility does not save - if the gang decided to collect a "tax" from the entire class, it is more difficult to hide than to seem "one of them";
have one point of support - a friend, a teacher, a safe place (library, first-aid post) where you can go.

Girls from the "insiders" are usually not directly abused, but they are kept under control through status and rumors - spreading a rumor about a girl in this system is as dangerous as hitting a guy. (This is my interpretation, not a direct quote from the canon.)
A strange girl for the gang is either a "resource" (to seduce, use, blackmail), or "do not touch" if she is connected with a strong guy from her own environment.
Stereotypes that live in this system

"Force = law". Whoever is stronger determines the rules; The weak are to blame for being weak.
"Gang = family". Many heroes (Seok-dae, Beom-suk, Young-yi) go to the gang because they are not understood at home or are beaten. The gang gives an affiliation that is not at home.
"Money = respect". The ability to get money (by any means) is valued higher than studying.
"Learning is for suckers" — but with an important exception: in Kanhak, one of the Soyuz schools, students are shown to be diligent and competitive in their studies. That is, the stereotype does not live everywhere: where the gang is closer to "business", the mask of a "normal school" is even useful.
"Asking for help is weakness" – so adults find out about problems too late: teachers, principals and parents in the story are shown as distracted and "disconnected" from the real life of children.

"School economics" – control over trade within the school, making money on the weak.
Fake Cases: For example, Jared (Kanhak) stole and framed Injan's apprentices to set the Wolf against them for his own reputation.
As one fights

with Numbers against one. Baseball bats, a crowd for one is a typical tactic of the elders from the sports club and street gangs.
Ambushes and "divide and rule". Forrest waited to attack Injan's group when they were separated.
Individual style of the strong. Wolf Kym is a wild, unpredictable style, great endurance, he laughs when he is beaten and feels almost no pain. Donald Na is a polymath, speed and accuracy, almost untouched in combat. Jake G is technical, strong, number two in the hierarchy.
Against them is calculation. Shi Eun (Gray in the webtoon) wins not by force, but by psychology, knowledge of physics and the use of the environment.
How they treat girls and guys

Here the canon shows a rather harsh picture, and part of it is my interpretation for your role-playing role.

Guys.

In the hierarchy, a guy is valuable as long as he is useful or strong. The weak one is used as a "workhorse" (money, errands, dirty work) - like Hyo Man manipulated Jun Tae into stealing phones.
The strong one is given a "place", but on the condition of loyalty: Donald quarrels with Wolf and Jimmy among themselves so that no one becomes a threat to his power.
The one who loses an important fight loses the status - like the Wolf after losing to Injan.
Girls.

In the canon, the girls in the gang meet, but their roles are mostly instrumental: Yulia Che is used to pass a bag of money and compromising material under the guise of a gift; Young-yi is a fugitive associated with the Seok-dae gang, she is on an equal footing with the guys and is respected for her courage; Seo Na-eun from season 1 uses his charm to pit the baseball team against Soo-ho

What gangs exist

1. Gil-so's gang (1 season of the drama). A street group of elders, into which Seok Dae and later Beom Seok are dragged in. They collect money from teenagers, keep a neighborhood, are associated with adult criminal figures: the owner of a bowling alley, who makes a living by stealing and selling motorcycles, and his henchman Baek Jin, who launders money.

2. Union (webtoon and season 2). This is the main criminal formation in history. A coalition of five schools (Daehyun, Ganghak, Hyun-shin, Yusun, Yeol-il) led by Donald Na (Na Baek Jin in the drama), who built it since middle school. Each school has its own leader, who reports to the head.

Hierarchy within the "Union" (webtoon):

Yoil is the center, the school of Donald himself. Kingsley Kwan, his "chief of staff", is also there.
Daehyun as Jake G, the second strongest fighter in the entire Soyuz; after Donald's death, it is he who manages affairs.
Kanhak - Wolf Kym. An interesting detail: Kanhak's students are shown to be diligent in their studies, a school with strict rules and a "polite" appearance.
Hyun Shin - Forrest Lee (formerly Miles Joo, who made deals with the Manwall gang and was banished).
Yusun is Jimmy Bae, the "lowest" step in the hierarchy; after his defeat, the school came under the control of Daehyun.
Against them are Injang (Shi Eun's school in season 2): Ben Park (Park Hoo-min), Alex Guo, Teddy Jin, Eugene Gale and others.

3. Intra-school gangs (like the Hyo Man gang in Injang) - manage the "black market" inside the school: students steal other people's phones, and the gang resells and earns.

What do they do (business)

Extorting money from students is a classic of both season 1 and webtoon.
A fraudulent gambling app that extorts money from teenagers (canon drama).
Stealing and reselling motorcycles is the business of adult boss Gil-so.
Money laundering for senior gangsters.
"School economics" – control over trade within the school, making money on the weak.

Level 3: "Power Outside of School" - Seniors and Money

This layer makes school showdowns truly dangerous.

Jung Seok-dae (Young-bin's older brother) He does not play by the school rules. For him, territory and income are more important than reputation, and fear is the best tool of control. He supports his brother not out of love, but out of calculation: it's easier to keep the neighborhood this way.
Park Jae-hui and Lee Jae-hak (ransomware group). They have a clear task: to raise money and keep students under control. Their strength lies in the fact that they act systematically: they do not just hit, but build a pressure scheme.
Gym manager, chat administrator, taxi driver. These are "shadow adults": they do not participate in fights, but support the system. The manager turns a blind eye to what is happening in his space. The chat admin deletes inconvenient messages. The taxi driver pretends not to see anything. In their hierarchy, the main rule is: "do not create problems."
What it looks like in the hallway: high school students are standing at the exit and watching who is leaving the school. The chat administrator writes: "No need to escalate." The gym manager nods, "Everything is under control."

How these levels collide in one scene

Imagine an ordinary evening: Young Bin arranges a skirmish in the corridor to show who is in charge here. Shi Eun calculates how to end the conflict quickly and without unnecessary injuries. The director passes by and pretends that nothing is happening. Mrs. Lee wants to intervene, but realizes that her words will not change anything. And the elders are already standing at the exit: for them, this skirmish is either a resource or a hindrance.

It is in these intersections that the series lives: Shi-eun wins the fight, but the system remains. Soo Ho defends his friend, but the school pretends that everything is fine. Beom-seok tries to smooth things out, but the pressure comes from several directions at once.

Lee Hae-woon and similar disciples. These are "potential targets": they have not yet chosen a side, but they are already feeling pressured. They are looking for support, so they go to Shi Un for advice. In the hierarchy, they are the most vulnerable — and the most mobile: they can break, join the bullies, or become allies of the "other side."
What it looks like in the hallway: Yeon Bin is standing in the center, his group is around him. Bom Seok is nearby, but a little to the side. Shi Eun and Su Ho follow their routes, not trying to be noticed. The rest either bypass this point or try to look like "one of their own".

Level 2: "Force by the Rules" – Official School

This hierarchy is supposed to protect, but in practice it often protects the reputation of the school.

Director Kim Hyun. Its main metric is "no complaints, no problems." He does not want to know about the violence because he does not know what to do with it and is afraid of the consequences for himself. In his system, the best conflict is the one that no one knows about.
Teachers. They have different strategies: someone does not notice (Kang Min-so), someone breaks up fights, but does not understand the reasons (Jang Myung-jin), someone sincerely wants to help, but he does not have tools (Mrs. Lee). In the hierarchy of teachers, those who "do not interfere with the system" are stronger than those who try to change something.
Librarian Mrs. Jeong, nurse, janitor Uncle Kim. These are "points of minimum safety". They cannot stop the system, but they can give a minute of silence: the library to hide, the first-aid post to record the injury, the far corridor to wait it out. In the official hierarchy, they are at the bottom, but for students they are often more important than all other adults.
What it looks like in the corridor: the director passes by and pretends not to see the tension. The physical education teacher breaks up the fight and says: "To the lesson." The librarian quietly nods to the one hiding behind the shelves: "It's quiet here."

Level 3: "Power Outside of School" - Seniors and Money

This layer makes school showdowns truly dangerous.

Level 1: "Strength on Schedule" - School Classroom

This is the most noticeable layer: everything is decided here in the corridors between lessons and during breaks.

Jung Young Bin (leader of the bully group) His power rests on fear and on the fact that he makes violence the "rule." He doesn't just hit – he creates a system where everyone knows: if you are not with him, you are against him. His strength is in publicity: he deliberately makes it so that everyone can see who is in charge here.
"Right hand" and support: Lee Hyun-bae (teasing and escalating), Shin Ga-ram (physical strength), Cho Ah-young (managing rumors). Each has their own function: together they keep the class in constant tension. If you remove one, the system still holds on, which makes it dangerous.
About Bom Seok. He is within this group in terms of status (the son of a deputy), but functionally he is a "shock absorber": he smoothes out conflicts, translates topics, does not allow the system to explode from internal contradictions. In the hierarchy, he is at the level of a "useful ally", but not a fighter.
Yeon Shi-eun and Ahn so Ho. They stand next to the system, but not in it. Shi-eun is dangerous because he breaks the logic of "strength = fists": he wins not because he is stronger, but because he is smarter. Su Ho is dangerous because he has his own strength and his own morality: he does not want power, but he will not allow pressure on his own people. For the system, they are "inconvenient exceptions".
and Jun-ho and Kim Won-seok. This is the "supporting layer": they are not leaders, but they make the pressure massive. Their motivation is simple – it's safer this way. In the hierarchy, they are at the level of "executors": they do small tasks, tease them, and create a threat background.
Kim Dong-hyun, Park Ji-hoon, Lee So-young. This is the "invisible layer": they try not to get on the radar of either leaders or victims. Their strategy is to be invisible. But they know the most: who is gathering where, who is goading whom, where the clash is brewing. In the system, they are like "sensors": they feel tension before anyone else.
Lee Hae-woon and similar disciples. These are "potential targets": they have not yet chosen a side, but they are already feeling pressured. They are looking for support, so they go to Shi Un for advice. In the hierarchy, they are the most vulnerable — and the most mobile

Technician Uncle Kim (cleaner in the far corridors)

Appearance. Elderly, calm, in simple work clothes. It moves slowly but surely. He looks like he knows all the nooks and crannies of the school and all its secrets.
Habits. He does his job and almost does not interfere. But if he sees someone crying in the corner, he doesn't scream, he just puts a bucket and a mop next to him and says, "Sit here until it feels better. No one will come in."
Weaknesses and fears. He is afraid that his kindness will be used to hide the traces of the fight. His vulnerability is that he wants to help, but does not want to become an accomplice.
That he hates. When teenagers spoil what he repairs and cleans. He does not tolerate when his advice is devalued: "what do you understand."
"How to break through to it". Respect his work: do not litter, do not make noise, do not hide evidence. If you just help him sweep or hold the door, he begins to see you as a person, and not "another problem student".
"Shadow" adults: those who hold the pressure

system School chat administrator (a woman from the PTA who moderates the general chat)

Appearance. Neat, collected, always with a phone in her hand. She speaks quickly, clearly, as if she is used to managing the flow of information.
Habits. Makes sure that there is no "panic" and "scandals" in the chat. He deletes messages where someone complains about conflicts, and writes template responses: "We'll figure it out", "No need to escalate".
Weaknesses and fears. Her weakness depends on her reputation: it is important for her to make the chat look "calm and productive". She is afraid that they will stop listening to her if she starts raising uncomfortable topics.
That he hates. When parents and students begin to "make waves". She does not like it when people write to her at night on "insignificant" issues.
"How to interact with her". Do not try to evoke emotions. It is better to write briefly, to the point, with facts: "At 14:30 in the corridor A, student X pushed student Y. There are witnesses." Then it responds as a task, not as a complaint.
A taxi driver who often drives the elders of the gang

Park Ji Hoon (the guy who is always late and makes excuses)

Appearance. A little disheveled, the backpack is on one shoulder, the uniform is not perfectly tucked in. It looks like he's always in a hurry.
Habits. He constantly looks at the clock and comes up with plausible excuses: "the bus was delayed", "mom asked for help". In fact, he just avoids the corridors where bullies usually gather.
Weaknesses and fears. His weakness is in the habit of lying in order not to face reality. He is afraid that if he does not lie one day, he will be immediately noticed and made a target.
That he hates. When he is caught lying and making a public scandal out of it. He doesn't like to be forced to "choose a side" – he just wants to be inconspicuous.
"How to break through to it". Do not pressure and do not shame. If you calmly say, "I don't care why you're late, I care that you're here now," he begins to trust and hides less.
Teachers and staff who appear in the episodes

Librarian Mrs. Jeong

Appearance. Calm, collected, wearing glasses on a chain. Always wearing a cardigan, even at school. She moves quietly, speaks softly, but her voice is still audible.
Habits. He knows who takes what from the library, and makes notes. If a student comes for the third day in a row to get books on the same topic, she can quietly ask, "Do you want this for a project or just to hide?"
Weaknesses and fears. He is afraid that the school will become a place where he cannot even hide behind a book. Her vulnerability is that she has almost no power, but she has responsibility for the space where children should be safe.
That he hates. When they make a fuss in the library and break the order. He can't stand it when books are used as a weapon or as an excuse for bullying ("you're back in the library, so you're weird").
"How to break through to it". Coming not for advice, but for business: "Can I sit here and do my homework?" – she appreciates respect for space. If you don't break the silence and order, it will imperceptibly cover you: it won't give you away if you're hiding.

Courier from the faction (the one who transmits messages and money)

Appearance. An ordinary guy in a delivery uniform: a cap, a backpack, neutral clothes. There is nothing "bandit" about it, and that is why it is invisible.
Habits. He always looks at his watch, speaks briefly, does not linger. His task is to transfer, take, leave.
Weaknesses and fears. He is afraid of making mistakes in details: confusing a place, time, person. For him, a mistake is not just a mistake, but a risk of losing his place in the system.
That he hates. When he is asked unnecessary questions. He can't stand it when teenagers try to "have a heart-to-heart talk": for him, it's work, not friendship.
"How to break through to it". Do not try to talk to him. If you need to convey a message, it is better to do it as clearly as possible and without emotions - then he will complete the task without unnecessary problems.
"Observer" students: those who see everything but stay away

Lee So-yeon (a girl from the parallel stream, often sitting in the back rows)

Appearance. Discreet: hair is tied in a low ponytail, a minimum of accessories, the school uniform fits a little loosely. She looks as if she is scanning the room all the time.
Habits. He keeps a "diary of observations" on his phone: he writes down who quarreled with whom, where the elders gather, who came with a bruise. He does it not for the sake of gossip, but to understand where it is dangerous.
Weaknesses and fears. She is afraid that one day her "diary" will be found and used against her. Her vulnerability is that she wants to be useful, but is not ready to become a target.
That he hates. When adults say "there is no bullying at school", although she sees the opposite every day. She can't stand it when her observation is mistaken for curiosity or schadenfreude.
"How to break through to it". Not to ask "to tell everything", but to ask specifically: "Did you see where X went?" – she answers point questions more willingly. If you don't devalue her notes, she can be a great source of information.

A nurse in a school medical center (not a nurse, but a young medical worker)

Appearance. A young guy looks like he has just graduated from college. Always in a white coat, but without unnecessary strictness: there is no "adult heaviness" in it.
Habits. He tries to be neutral: "I only record injuries and call them if necessary." But sometimes he quietly asks: "Was it accidental or were you pushed?" – and if he is answered honestly, he tries to help in his own way (for example, write down the time and details so that it is not lost).
Weaknesses and fears. He is afraid of doing something not according to the instructions and getting reprimanded. His vulnerability is that he wants to help, but is bound by regulations.
That he hates. When students hide the truth, and then the situation gets worse. He doesn't like it when adults devalue his work: "you're just handing out thermometers here."
"How to break through to it". Speak directly and calmly: "I need fixation so that it doesn't get worse." He responds to a request for protection, not to emotions.
Characters who show the "adult" side of pressure

A manager from the gym who "covers" part of the

gang Appearance. A calm, well-groomed man of 35-40 years old, in clean sportswear, but with a heavy look. He smiles just enough to seem normal, but there is no warmth in the smile.
Habits. He keeps his distance and speaks only to the point. He likes to repeat phrases like "we don't make problems, we solve them" or "everything is under control."
Weaknesses and fears. His weakness is that the appearance of "cleanliness" is important to him: he does not want adults or the police to see how he is connected to teenagers. He is afraid of losing this delicate balance between the "ordinary manager" and the "person who solves issues".
That he hates. When teenagers begin to think that they can act without his knowledge. It does not tolerate amateur activity, because it breaks the system.
"How to break through to it". No way, if you are an ordinary schoolboy: he does not see you as a player. The only language he understands is power, money, or connections.

Choi Min-jae (a guy from the parallel class who knows "all the corridors")

Appearance. Thin, fast, moves as if he is constantly late. He wears a jacket a size larger to look casual and "not catch the eye".
Habits. He likes to walk along the quietest and farthest corridors, where there are fewer cameras. He knows where to hide in school, where teachers almost never appear, and where the elders collect money.
Weaknesses and fears. His weakness is that he depends on "information as currency": he shares rumors in order to remain useful and not become superfluous. He is afraid that one day he will find himself in the center of a conflict, when information ceases to be a shield.
That he hates. When his information is devalued ("you're talking again"). He doesn't like it when they use his knowledge, and then pretend that they don't know him.
"How to break through to it". Respect his "insiderism": do not ridicule rumors and do not demand proof. If you take his information seriously, he becomes a reliable guide through the school system.
Adults who appear in a couple of scenes, but set the tone

Teacher Park (physical education in another shift)

Appearance. Strong, short-haired, looks like a former athlete. He speaks little, but loudly.
Habits. She believes that "school is also a discipline": if a student misses a lesson, he must work out push-ups during the break. His approach is tough, but without malice, just "it's the way it should be".
Weaknesses and fears. He is afraid of not being able to keep control over the class, because then "everything will go haywire". His vulnerability is that he solves problems by force and rules, not by conversation.
That he hates. "Softness" and when students try to argue instead of doing. He does not tolerate when his authority is questioned.
"How to negotiate with him". Do not argue and do not make excuses. It is better to say: "I understand, I will do it," and only then, if necessary, carefully ask for another format. For him, respect for the rules is respect for him.

Kim Ji Won

habits. He notices everything: who stands with whom, who said what to whom. He quietly warns those who are in danger, but tries not to draw attention to himself.
Weaknesses and fears. She is afraid that her good intentions will turn against her. Her vulnerability is that she wants to help, but is not ready for open confrontation.
Park Hyun is a

habit. He transmits rumors not for the sake of gossip, but so that people are aware and can protect themselves. He keeps neutrality, but at the same time remains on the side of justice.
Weaknesses and fears. He is afraid of being caught between two fires and becoming a target for both sides. His vulnerability is in the need to choose: to be silent or to speak.
Students who are almost unnoticed, but they are important to the

atmosphere Kim Dong-hyun (classmate from the "middle" of the class)

Appearance. A guy who is always wearing headphones and tries to be inconspicuous: he slouches a little, looks at the floor, a backpack on both shoulders. He looks like someone who just wants to finish his studies and not get on the radar of either bullies or "heroes".
Habits. Constantly texting in the class chat to be aware of where and when a skirmish is brewing. He likes to take a thermos of tea with him and eat something quiet (cookies, bar) - this way he feels calmer.
Weaknesses and fears. He is afraid that if he proves himself even a little, he will immediately be chosen as the next target. His vulnerability is that he sees everything, but does nothing: it gnaws from the inside.
That he hates. When adults ask "what did you see?" – because he saw, but was silent. He can't stand "mutual cover-up", when everyone pretends that nothing is happening.
"How to break through to it". Do not demand courage from him. If you just sit quietly next to him and don't press, he begins to slowly share information: where they gather, who teases whom. It is important for him that his silence is not considered a betrayal.

Father about bom soka

appearance. A stately, well-groomed, "political" image: a suit, confident gestures. His smile is more of a mask than an emotion.
Habits. Evaluates people by status and usefulness. He likes to keep his distance and remind him of the "duty of the family".
Weaknesses and fears. His weakness is reputation: he is afraid that someone will see what he really is. The fear is to lose face and control over her son, who can "ruin everything".
Adults at the School

of Mrs. Lee

Habits. She tries to talk to her students, but quickly finds that her words are not heard. He tries to notice the details: who came with a bruise, who is silent in the lesson.
Weaknesses and fears. She is afraid that her interference will only make it worse, and at the same time she is afraid of not interfering. Her vulnerability lies in the limitations of power: she can notice, but she cannot protect.
Director Kim Hyun

Habits. He keeps his distance, communicates through reports and statistics. She loves phrases like "we have no complaints" and "let's not wash dirty linen in public."
Weaknesses and fears. He is afraid of inspections, scandals, loss of position. Its vulnerability is that the system it protects itself becomes a source of danger.
Supporting

Students of Lee Hae Woon

Habits. He tries to be inconspicuous, lowers his head when he passes by bullies. In a conversation with Shi Un, for the first time, he tries to formulate what he wants: not to be a victim, but not to become an aggressor either.
Weaknesses and fears. He is afraid of taking the wrong step and becoming a target. His vulnerability is in the lack of support: he is looking for someone who will tell him how to survive.
Lee Joon-ho

Habits. At first, he stays close to bullies so that he is not touched, then he begins to look for other ways. He often looks around, checking who is watching him.
Weaknesses and fears. He is afraid of being left alone and at the same time afraid of being part of a bad company. His vulnerability is uncertainty: he has not yet chosen a side, and this makes him especially nervous.

"How to break through to it". Only through strength and clear boundaries: he respects those who do not bend, but also do not get into trouble for no reason.
Lee Hyun-bae, Shin Ga-ram, Cho A Young (Young-bin's band)

Lee Hyun-bae. The one who builds up the atmosphere. He likes to tease, throw prickly phrases to provoke a conflict. His weakness is to depend on the leader's approval: without Young-bin, he loses confidence.
Shin GaRam. Physical strength of the group. He acts on command, does not like to think. His fear is that he will not be "cool enough" if he cannot prove his strength with action.
Cho A Young. Spreads rumors, manages information. Her weakness depends on her status: she holds on to the group because she feels vulnerable outside of it.
Byun

Joon-hee family (Soo-ho's grandmother)

Appearance. Small, neat, in simple clothes. The smile is warm, but in the eyes there is often anxiety for the grandson.
Habits. He cooks a lot and tries to feed Soo-ho, as if through food you can protect him from the whole world. He loves order and silence.
Weaknesses and fears. She is afraid that her grandson will break down under the pressure of the street and school. Her vulnerability is helplessness: she cannot fight for him, so she prays and waits at home.
Kim Sung-kyun (Shi Eun's father)

Appearance. Strong, athletic, with a straight posture. The look is strict, but not angry, rather demanding.
Habits. Everything translates into discipline: "do it ten times", "keep the rhythm", "don't lose focus". Even in a conversation with his son, he seems to give instructions.
Weaknesses and fears. He is afraid that his son will grow up "soft" and will not be able to stand up for himself. His vulnerability is that he does not know how to talk about feelings, only about rules.

Antagonists

: Jung Young-bin

appearance. Fit, he makes sure to look impressive: he straightens his shoulders, walks as if he "holds the territory". The haircut is neat, but a little more casual than Bom Seok's - this is part of the image of a "dangerous guy".
Habits. He likes to demonstratively check who is looking at him, and line up people so as to be the center of attention. Before a skirmish, he can deliberately provoke, throwing short phrases to make the opponent lose his temper.
Weaknesses and fears. The main weakness is dependence on someone else's recognition. He is afraid that if he ceases to be the "strongest", he will become a nobody. His fear is to disappoint his mother and lose control of his group.
That he hates. Weakness in others and any hint that his authority can be challenged. He can't stand being put before a choice where there is no "winner".
"How to break through to it". Almost impossible through kindness. The only way that has at least a little effect on him is direct honesty without humiliation: not "you're wrong," but "you can decide it differently." But even this rarely works, because for him, authority is more important than logic.
Jung Seok Dae

appearance. He is taller and more massive than his brother, he moves calmly, but heavily - you can feel the adult, brute strength in him. The gaze is direct, evaluating. He dresses simply, but expensively, to emphasize his status.
Habits. He always keeps his distance and speaks only to the point. He likes to control the territory: he checks who is standing where, who communicates with whom.
Weaknesses and fears. His weakness is that he relies too much on fear as a tool. He is afraid of losing control over "his zone" and believes that any compromise is a loss of power.
That he hates. Disobedience and any attempts to "play by their own rules". He does not tolerate when someone tries to be smarter than him in negotiations.
"How to break through to it". Only through strength and clear boundaries: he respects those who do not bend, but also do not get into trouble for no reason.

That he hates. When someone uses force against those who are weaker. He can't stand it when his kindness is mistaken for weakness.
"How to gain trust". Be reliable: if you promised to be there, be. Do not try to "persuade" him in a moment of rage, it is better to say: "I am with you, but let's do it in such a way that you do not lose what is dear to you." For him, this is more important than any beautiful words.
About Bom Seok

appearance. A little shorter than Su Ho, but collected, neat. It always looks "as it should": the uniform is ironed, the hairstyle is styled. This is not about fashion, but about an attempt to meet the expectations of his father, a deputy.
Habits. He tries to smooth out conflicts: he changes the topic, jokes, offers a compromise. He often checks the phone, as if waiting for approval or scolding. In moments of severe stress, he begins to nervously adjust his collar or sleeves.
Weaknesses and fears. Most of all, he is afraid of disappointing those who are truly dear to him, and at the same time he is afraid that his kindness will be perceived as cowardice. His vulnerability is a sense of uselessness: he does not want to be a "convenient son" or a "convenient friend".
That he hates. Falsehood and ostentation, especially when adults hide behind their "reputation" and pretend that everything is fine. He can't stand it when people are judged by their family status.
"How to gain trust". Do not devalue his attempts to settle everything peacefully: for him, this is not cowardice, but a way to keep people around. Show that you appreciate his ability to see both sides and do not force him to choose "to be tough" or "to be himself".

The main characters

are Young Shi Eun

Appearance. Medium height, not overpumped, but wiry. He looks like an "ordinary" schoolboy: a neat haircut, most often in a school uniform without unnecessary details. The face is calm, almost without facial expressions - emotions can be read from the eyes and the position of the shoulders.
Habits. Before a conflict, he discreetly scans the room: where are the corners, chairs, who is standing closer. In quiet times, he reads a lot or solves problems, as if he trains the brain as well as the body. He can listen to voice messages from his mother and answer them aloud when no one is around.
Weaknesses and fears. He is afraid not so much of pain as of the fact that his "cold calculation" will be mistaken for heartlessness. It's hard for him when his loved ones (Soo-ho, Beom-seok) take risks because of him. His vulnerability is in loneliness: he is used to keeping everything to himself and does not ask for help well.
That he hates. Hypocrisy and when the strong justify violence by the "rules of the pack". He can't stand it when someone hides behind authority to put pressure on the weak.
"How to fall in love with yourself" (that is, how to gain trust). There is no need to try to be "cooler" or impress with strength. It is important for him that a person is honest and straightforward. If you don't turn away at the moment when everyone is running, and at the same time do not demand that he "become more emotional", he begins to trust you.
Ahn so Ho

Appearance. Tall, strong, with broad shoulders - the same guy at whom everyone looks back in the corridor. He has an open, almost childlike smile that is in stark contrast to the way he fights. The haircut is simple, without styling.
Habits. He constantly checks if everything is all right with his grandmother: he calls, reminds that he will come on time. He likes to eat something simple and hearty to "hold his strength". When stressed, he clenches his fists and immediately wants to solve the problem by force, and only then thinks.
Weaknesses and fears. His main weakness is his loved ones: he is ready to get into any fight if someone threatens those he loves. He is afraid that one day he will not have time to protect him, and because of this, he becomes even more short-tempered.
