• Build: Massive, athletic, and well-proportioned. He has very broad shoulders, a well-defined chest and abs, and narrow hips. Taesong maintains his perfect physical shape through constant fighting practice.

🩸 Physical features

• A scarred body: His back, chest, and arms are covered with the numerous marks of a life of crime—marks from deep knife cuts, fights, and old gunshot wounds. Each scar is a reminder of the brutality he endured on his path to power.
• Incredible physical strength and fighting skills: Despite being the boss and usually giving orders, Taesong is a deadly fighter himself. He is skilled in hand-to-hand combat, is a master knife fighter, and is proficient with firearms. In one key scene, he single-handedly takes down an entire group of armed attackers.
• High pain threshold and endurance: Thaeson is able to withstand serious injuries without losing his fighting ability. Even after serious car accidents or assassination attempts, he recovers quickly.
• Peculiarities of voice and facial expressions: Has a very low, velvety, but commanding voice. His face almost always maintains a mask of complete calm (the so-called "poker face"), and the only thing that betrays his rage or excitement is the narrowing of his pupils and a barely noticeable predatory squinting.

📖 Biography: The Path to the Bloody Throne

• Childhood and youth: Thaeson was drawn into a criminal environment at an early age. He grew up in cruel conditions, where he had to gnaw away at his right to life with his fists and greed.
• A Fateful Encounter in the Past: As a young gangster, Taesong came to collect debts at Soo-yoon's mother's funeral. There, he saw a little boy boxer, who was beating his fists until he was bleeding, desperately trying to protect his mother's coffin from the adult collectors. This steadfastness of Soo-yoon's impressed Taesong to the core and was the beginning of his years-long hidden obsession.
• Rise to power: Thanks to his intelligence, ruthlessness, and physical strength, Thaeson quickly rose through the criminal ranks. He headed the credit organization "Sadupa" and brought a significant part of the city's shadow business under his control.
• Manhwa plot arc: Taesong finds Soo-yoon years later, when he is already broken by a leg injury and his father's debts. He forces the boy to become his plaything. However, after going through betrayals by subordinates, attempts by competitors, his own amnesia, and a long psychological struggle with Soo-yoon, Taesong decides to completely change his life. He destroys the top of the enemy gangs, legalizes capital, and consciously renounces the status of a mafia boss to stay with Soo-yoon as his legal partner and protector.

👤 Appearance: Cold monumentality

Park Tae-sung has the classic, yet very predatory and masculine appearance of an alpha character:
• Build: Incredibly tall (about 190 cm), broad-shouldered, with a sculpted and massive body. His skin is covered with numerous scars from knife and gunshot wounds — silent evidence of his criminal past.
• Face: Sharp, as if carved from stone, facial features, a strong jawline, and thin lips that rarely smile sincerely.
• Hair and eyes: Has light (ash blonde) hair neatly combed back. Eyes of a cold gray or light brown shade with a heavy, piercing gaze that can intimidate anyone.
• Style: His "armor" consists of impeccably tailored expensive classic three-piece suits in dark shades (most often black), perfectly pressed shirts and ties. Even during violent confrontations, he tries to look elegant.

🧠 Character: From "Black Flag" to absolute devotion

The psychological portrait of Theson changes dramatically over the course of the three seasons of the story:
• Beginning (Absolute Tyrant): A selfish, cruel, manipulative, and domineering man. He has no empathy, and sees people as tools or property. Taesung suffers from a morbid obsession and paranoia—if he likes something, he takes it by force and locks it in a “golden cage.” His attraction to Sooyoung is initially sadistic and destructive.
• Crisis Point (Broken Pride): Taesong is deeply lonely. He is unable to express healthy feelings because he was raised in a criminal world where showing affection is tantamount to death. However, beneath this armor lies a vulnerability towards the only person he has allowed to be close to him: Soo-yoon.
• Finale (Transformation into a Protector): Realizing that his own cruelty nearly destroyed Soo-yoon, Taesung breaks his selfishness. He becomes patient, caring, and willing to sacrifice his own life and status for the safety and comfort of his beloved.

Kwon Soo-young (Kwon Soo-young)

• Role: Main character (protagonist).
• Who he is: A former talented amateur boxer. He was forced to retire from the sport permanently due to a serious leg injury, so he now uses crutches to get around.
• Characteristics: Despite his disability and a host of life problems, Suyun has an incredibly resilient, proud, and fiery character — he never runs away from a fight or allows himself to be humiliated. He finds himself trapped because of his late father's huge debts to the mafia.

3. Lee Min-hyuk

• Role: Secondary protagonist (second love interest).
• Who he is: One of Thaeson's subordinates and former henchman. A muscular man with tattoos and bangs that cover his eyes.
• Characteristics: Unlike his boss, Minhyuk is much more lenient towards Soo-yoon. They grow closer, and Minhyuk becomes Soo-yoon's close friend and protector in the dangerous world of the mafia. He genuinely cares for the boy, creating a love triangle.
Also playing an important role in the plot are:
• Song Ji-sung: Soo-yoon's former boxing partner and first love, who is trying to win back his boyfriend but has an abusive past.
• Kim Sang-cheol: A senior실장 (manager) in the Daesong organization with a large scar on his face who helps run things and keep things in order.

At the beginning of the story, Park Tae-sung appears as a classic "Red Flag":
• Domineering and ruthless: He knows no pity for debtors, is used to manipulating people and completely controlling everything around him.
• Obsessed: His interest in former boxer Soo-yoon quickly develops into a deep, toxic, and destructive obsession. He sees Soo-yoon as his “property” or “toy,” punishing any signs of disobedience.
• Hidden Vulnerability: Behind the mask of a brutal mobster lies deep psychological trauma and inner loneliness. Taesong is unable to express healthy attachment, so his love comes across as violence and pressure.

⛓️ Evolution and role in the plot (Warning, spoilers!)

Taesong and Soo-yoon have a secret past together since their teenage years, which Soo-yoon can't remember due to a head injury. Taesong met Soo-yoon when he was still a teenager and desperately fought with debt collectors at his own mother's funeral. The boxer's strength of spirit and tiny but unbreakable fists are forever etched in the gangster's memory.
Over the course of three seasons, Taesong's character undergoes enormous changes, especially after a turning point when Soo-yoon suffers temporary amnesia due to another injury. Seeing Soo-yoon defenseless and free from old resentments, Taesong breaks down inside. He turns into the so-called "Green Flag": he begins to sincerely and tenderly care for Soo-yoon, tries to win his heart in a healthy way, and protects him from the dangers of the criminal world.

The plot of the manhwa "Legs That Don't Walk" tells a dramatic, criminal, and psychologically intense story that begins with a fierce collision of two completely different worlds.

🎬 The beginning of the story (The ending)

Kwon Soo-yoon was once a professional and very promising boxer. However, due to a terrible leg injury, he is forced to forget about the ring forever. Now he moves only with the help of crutches and barely makes ends meet. In addition to his lost dream, the boy is burdened with the inheritance of his late father - a huge debt to ruthless collectors.
Unable to pay, Soo-yoon falls into the hands of Park Tae-sung, the cold, domineering, and dangerous boss of the credit mafia organization "Sadup". Seeing the crippled but proud boxer, who, even in the face of death, does not bow his head and tries to fight, Tae-sung feels a wild, almost morbid curiosity about him. Instead of simply killing the boy or selling his organs, Tae-sung offers a "deal": Soo-yoon must work off the debt by becoming his personal subordinate and following his every order.

⛓️ Plot development and main conflicts

The plot of the manhwa is based on three main lines:

1. The mystery of the past:
   It gradually becomes clear that this is not their first meeting. Taesong and Soo-yoon crossed paths in their teens under very tragic circumstances. Then little Soo-yoon protected his mother's coffin from bandits, and Taesong even then had this image of an indomitable boy in his heart. However, due to a serious head injury, Soo-yoon has completely forgotten those events, and Taesong uses this to manipulate him.
2. Love triangle and danger:
   Within the gang, Soo-yoon becomes close to Lee Minhyuk, Tae-sung's right-hand man. Minhyuk, unlike his boss, shows Soo-yoon genuine warmth, care, and tenderness. This causes Tae-sung to have wild bouts of jealousy and makes the atmosphere in the gang explosive. At the same time, Soo-yoon has to survive in the dirty criminal world, where Tae-sung is constantly being targeted by his rivals.
3. Turning point and role change:
   The relationship between Taesong and Soo-yoon begins as a classic case of abuse and coercion. But at a certain point (after another injury and accident), Soo-yoon temporarily loses her memory. Taesong, looking at the defenseless Soo-yoon, who no longer looks at him with hatred, breaks down inside. He realizes how much and sincerely he loves the guy. From that moment on, Taesong radically changes his behavior: he begins to protect Soo-yoon, treat his legs and tries to become a reliable "green flag" for him.

🏁 How it all ends

Despite bloody clashes with enemy gangs, internal betrayals, and severe psychological trauma of the characters, the story has a happy ending:
• Taeseong and Sooyoung stay together. Their relationship undergoes a complete transformation from hatred and submission to true, mutual, and mature love.
• Suyun finally has successful surgery on his legs and gets the chance to walk again without crutches.
• They leave the criminal world in the past to start a peaceful life together.

1. Bloody purge of competitors (Gang War):
   Taesong didn't just write a resignation letter. Throughout the third season of the manhwa, a full-scale war with the enemy group "Kuryongpa" and their boss unfolds. Taesong physically eliminated or put behind bars all of his main enemies and corrupt politicians (including the city mayor) who kept him on the hook. He left the mafia world only when there was no one left in it who could take revenge or catch up with him.
2. He transferred power legally:
   Thaeson did not disband his Sadupa gang. He completely restructured the business, transferring most of the capital into a legal channel, and transferred the management of dirty affairs to trusted people who remained to manage in his place. He effectively became a “shadow shareholder” who no longer participated in the street brawls.
3. Amnesia as a psychological trigger:
   The most important point is that Taesong was obsessed with power and control, and he was the very "psycho." But when he temporarily lost his memory due to an accident, his personality was "reset." He saw a life without paranoia, fear, and crime. When his memory returned, he realized that if he remained a mafia boss, Soo-yoon would sooner or later die at the hands of his enemies. His love for Soo-yoon turned out to be stronger than his lust for power.
