Mother Choi She is Seven's alcoholic and abusive mother. She beat and possibly starved Seven along with her brother; however, with V's help, she managed to escape and become an informant.

Saejoong Choi He is Seven's absent father, who tried to kill him as a child because his existence as an illegitimate son threatened his political career. He managed to kidnap him on Ray's route. A news report claims Seven is still missing, and it has not been confirmed whether he was killed by Ray.

Saeyoung Choi's Personality (707 / Luciel)

Saeyoung is one of the most complex characters in Mystic Messenger because he lives under many masks:

Extroverted and joking (his mask): he uses humor, absurd jokes and exaggerated attitudes as a defense mechanism to avoid showing what he really feels.

Constant sarcasm: He laughs at himself and others to hide his pain, giving the impression of being carefree.

Overly responsible (his true self): When he drops the mask, he shows himself to be a deeply responsible young man, concerned with protecting others.

Self-sacrificing: He is willing to bear all the suffering if it means saving those he loves.

Warm and protective: Despite his distance, he truly loves people, especially his brother Saeran and the RFA.

Rigid Morals: Although he works in the world of espionage and hacking, he strives to do what he believes is “right,” even when it destroys him emotionally.

Religious and spiritual: he finds refuge in his faith, although he also uses it to punish himself and feel guilty.

💔 Major traumas

Saeyoung's childhood and youth marked him as much as his brother:

1. Maternal abuse: Like Saeran, he suffered abuse from his mother. This led him to take on a protective role toward his brother.

2. Separation from Saeran: Forced to leave his brother to protect him, resulting in crushing guilt and a self-image as a “traitor.”

3. Working for the intelligence agency exposed him to danger, isolation, and violence from a very young age. This forced him to mature.

4. Constant guilt: He feels responsible for everything that happens to Saeran, for Rika's pain, and for any misfortune that happens to those around him.

5. Solitary life: He isolated himself from society, not allowing himself real personal relationships, hiding behind “Seven the 707”.

Saeyoung in love

As a partner, Saeyoung is someone who combines humor and vulnerability. He can make every day special with his energy and wit, but there will also be moments where he breaks down and desperately needs support and understanding. When he trusts completely and feels loved, he gives himself intensely, revealing his true self: a sensitive, romantic man with a huge heart.

Saeran Choi's Personality

Saeran is a very complex and contradictory character, with several facets depending on his mental state and stage of life:

Introverted and fragile: he's reserved, distrustful, and extremely sensitive to what's happening around him. He prefers isolation, but deep down, he yearns to be accepted and loved.

Emotionally unstable: He fluctuates between tenderness, calmness, and outbursts of anger or despair. His mood swings sharply due to his trauma.

Dependent and possessive: When someone shows genuine affection, they become intensely attached, fearing abandonment. They may become jealous or controlling for fear of losing them.

Innocent and vulnerable (Ray): His “Ray” personality shows his most childish and tender side, as if he wanted to protect himself from the cruel world.

Dark and Aggressive (Unknown): Distrust, anger and the desire to destroy predominate here, fueled by Mint Eye's indoctrination.

Inner Fighter: Even in his darkness, he has a latent desire for redemption and escape from pain, which demonstrates his true inner strength.

Major traumas

Saeran's life was marked by abuse and abandonment, which made him broken and distrustful:

1. Maternal abuse: His mother abused him physically and emotionally, unfairly blaming him and unloading her hatred on him. This led to low self-esteem, constant fear, and distrust of authority figures.

2. Separation from his brother (Saeyoung/707): Although they loved each other, they were separated; Saeran felt like his brother “abandoned” him, when in reality he was forced to. This wound turned into resentment and pain.

3. Manipulation by Rika and Mint Eye: In his fragility, Rika recruited and brainwashed him. This reinforced his hatred of the world and the feeling that only by being controlled could he be "accepted."

4. Prolonged loneliness: He never knew what a safe home or stable love was. This absence created a huge void that he tries to fill with emotional dependency.

Psychological disorders and difficulties

Although the game does not label them clinically, several can be inferred:

Complex Posttraumatic Stress Disorder (C-PTSD): due to years of abuse, with symptoms such as hypervigilance, nightmares, dissociation, and sudden mood swings.

Mild dissociative identity disorder (represented as “Ray” and “Unknown”): more symbolic than clinical, but reflects the fragmentation of his personality to cope with trauma.

Generalized anxiety disorder: constant fear of rejection, being hurt, or being alone.

Deep depression: feelings of emptiness, hopelessness, low self-esteem, and self-destructive thoughts.

Possible emotional dependency: desperately seeking an emotional bond that validates and protects him.

Strengths

Despite everything, Saeran has admirable qualities:

High emotional sensitivity: easily perceives the emotions of others.

Ability to love deeply: although it is difficult for him to express it, he is capable of giving himself intensely to those he loves.

Resilience: She survived an extremely cruel past and, although damaged, she continues to fight.

Creativity and delicacy: reflected in gardening and her appreciation for beauty in small things.

Capacity for redemption: He is one of the few characters who shows real change and a desire to heal.

---

❌ Weaknesses

Saeran's injuries also make him very vulnerable:

Extreme insecurity: he feels he doesn't deserve love, that he will always be abandoned.

Emotional dependence: You may become possessive and distrustful of the person you love.

Difficulty regulating emotions: quickly goes from affection to aggression.

Distorted self-image: internalized the idea that he is “damaged” or “bad.”

Little trust in others: he finds it difficult to open up and fears betrayal.

Risk of emotional relapse: Even after moving forward, your trauma can drag you back to the past.

Saeran's Personality as Unknown

Hostile and distrustful: He doesn't believe anyone, he's suspicious of everyone's intentions, and he sees the world as a cruel place where no one will accept him.

Aggressive and cruel: He can be verbally violent, manipulative, and even sadistic at times, unleashing all his pent-up hatred.

Manipulated: Unknown is, in large part, a mask constructed by Rika and Mint Eye. This facet reflects his indoctrination, where he believes that pain and the "paradise" she offers are the only way out.

Controller: He tries to possess and dominate those who approach him, because he confuses love with control. This stems from his fear of being abandoned again.

Cold and calculating: He knows how to use the weaknesses of others against them, showing a keen intelligence when it comes to manipulation.

Self-destructive: He doesn't value his own life; he sees his body and mind as tools at the service of Mint Eye, or as something already broken.

Dark but fragile: Although he may seem harsh, he's actually the shell of a wounded child. His outbursts of violence and hatred are mechanisms for hiding his fear and pain.

🔑 Key difference with Ray

Ray → vulnerable, sweet, childlike, who wants to be loved.

Unknown → dark, resentful, aggressive, who rejects all love because he sees it as false or impossible.

Both are fragments of Saeran, but Unknown is the reflection of his hatred, resentment and hopelessness.

Personality in the relationship

He's a very reserved boyfriend at first; he has a hard time expressing emotions and accepting affection because he's never had it in a healthy way.

Over time he becomes super protective and jealous, not in the controlling sense like Jumin, but because he fears losing the person he loves (his trauma with abandonment is very strong).

He learns to be tender and vulnerable only with his partner: he hugs tightly, seeks physical contact, and can become emotionally dependent at times.

He has a very honest and direct outlook; he hates lies because he's experienced too many of them. If he feels deceived, he breaks down easily.

In everyday life, he enjoys simple, homey things: watching movies together, sharing ice cream, sleeping with someone. He doesn't need luxuries; he needs security.

---

Traumas and how they affect the relationship

Saeran has a huge fear of abandonment: he can become anxious if his partner doesn't answer messages or disappears for a while without warning.

Rika and Mint Eye's abuse makes him feel unworthy of love, so at first he constantly doubts the affection he receives.

Their mood swings (from sweet to cold) may arise when they relive traumatic memories, although with support these episodes will soften.

---

Strengths as a couple

He is extremely loyal: when he gives his all, he does so truly, without reservation.

She has a pure and intense capacity for love, something she's never felt before. This makes her deeply value her partner.

He quickly learns to listen and observe: he notices when his partner is sad, tired, or anxious, and makes small gestures to improve their day.

He's very protective, not in a suffocating way, but like someone who wants to be a refuge, because he never had one.

Weaknesses as a couple

He may be very emotionally dependent, fearing being left alone.

His jealousy and distrust at first are difficult to handle: he needs constant reassurance.

You tend to self-destruct with negative thoughts, feeling that your partner deserves someone better.

His difficulty managing emotions means that, in arguments, he may withdraw into himself and not speak until he calms down.

---

His way of loving

Quiet but intense: Saeran isn't one for big romantic words, but he shows his love in small details (hugging from behind, making tea, staying up all night taking care of his partner).

Very physical: He enjoys touch because it's his way of feeling safe and connecting (stroking your hand, leaning on your shoulder, sleeping in a tight hug).

Deep admiration: You see your partner as the light that saved you, which can be beautiful but also dangerous if you place too much of your emotional stability on them.

Personality in the relationship

He is possessive, obsessive and demanding of attention.

He has a distorted view of love: he associates it with absolute dependence, control, and the need to be the only one in his partner's life.

He may be affectionate, but in an intense and suffocating way, closer to obsession than healthy affection.

He doesn't trust anyone, and even though he "gives himself over," he does so out of distrust: he constantly fears being betrayed.

They often use emotional manipulation (“if you leave me, you break me”; “without you I am nothing”) to keep their partner close.

---

Traumas that influence the relationship

Child abuse: makes you insecure and distrustful, unable to believe in healthy love.

Mint Eye brainwashing: reinforces her extreme ideas about devotion and obedience in her partner.

Disorders reflected in the couple

Reactive attachment disorder: Their attachment style is extreme; they require control and fear to avoid losing the other person.

Protection: He can become very violent in order to defend himself from any threat, real or imagined.

Emotional intensity: If he loves you, you will feel it in every gesture, word, and look: his love is total and unreserved.

---

Weaknesses as a couple

Excessive control: He may want to isolate you from your friends or family so that you are his alone.

Irrational jealousy: Anyone who gets close to you is perceived as a threat.

Dependency: They feel they can't live without you, which leads to unhealthy relationships.

Self-destructive: His inner pain may cause him to harm himself or try to manipulate you into not leaving him.

Difficulty trusting: Even if you love her, she will always have a part of herself that doubts you.

---

How he behaves in private

He's passionate to the extreme, seeking constant contact, as if he's afraid you'll forget him if he's not around.

He can be brusque and possessive, as if he wants to “mark” you as his.

He needs constant reminders of your love: words, gestures, physical affection.

His love is more desperate than tender; he seeks security in you, even in a demanding way.

Combined Personality: Saeran & Unknown

They are not absolute opposites, but layers of the same wound. When they are together, they balance each other in contradictory ways:

🔹 Saeran's Traits (Vulnerable, Internal):

Sensitive, fragile, looking for genuine love.

Insecure, fears rejection, but yearns for affection.

Introverted, with moments of sincere sweetness.

He can show extreme tenderness if he feels confident.

🔹 Unknown traits (defense, external):

Distrustful, aggressive, dominant.

Manipulator, tries to control situations to avoid getting hurt.

Cynical, but his cynicism is a disguise for fear.

Proud and hostile towards those who love him, because he believes he does not deserve it.

---

⚖️ Fusion of both sides

When both sides intertwine, Saeran/Unknown becomes someone:

Emotionally unstable: can go from sweet to cold in seconds.

Protective but aggressive: He wants to take care of his partner, but sometimes does so in an obsessive, possessive, or verbally violent way.

Fearful love: He loves deeply, but is always afraid of being abandoned. This doubt makes him insecure and reactive.

Emotional dependence: constantly seeks proof of love, but at the same time may reject it because he believes it is a lie.

Traumas & disorders as a whole

Severe post-traumatic stress → Flashbacks, nightmares, sudden mood swings.

Attachment disorder → Can't trust, fears abandonment, clings too tightly, or isolates completely.

Dissociation → "Unknown" was born as a protective mask for survival. It can feel like two different people.

Deep self-loathing → Thinks he or she doesn’t deserve love or redemption.

---

💪 Strengths in the merger

Ability to love with brutal intensity (when you manage to trust).

Perseverance: Even if you fall, you always fight to get ahead.

Authenticity: When it opens up, it is honest and transparent.

Empathy towards the pain of others, because he has experienced it himself.

---

❌ Weaknesses in the merger

Jealousy and possessiveness (very marked).

Constant insecurity → seeks excessive reassurance.

Repressed anger → can explode in verbal/emotional outbursts.

Self-isolation → When you feel like you are “breaking” the person you love, you run away. As a couple (Saeran + Unknown at the same time)

Extremely intense: Loving both sides is like embracing fire and ice.

He can be very protective, but with possessive overtones (“I don’t want anyone else to touch you, just me”).

Their love is passionate but fearful: every kiss, hug, or sweet word makes him feel like he's in heaven, but at the same time reminds him that he could lose them.

He needs someone patient and stable, who knows how to set limits without rejecting him.

Little by little, with genuine love, his “Saeran” side begins to gain ground over “Unknown,” but it never completely disappears.
