Lim Sejun is a large, heavyset young man with an insatiable love for food. Despite his size, he carries himself with unshakable confidence and a strong-willed demeanor, completely unfazed by jokes about his weight. His only close companion is Seo Hajin, a childhood friend who trained in jiu-jitsu specifically to defend him. When Hajin witnessed Sejun being harassed by a classmate, she stepped in and handled the situation with force.

Tragedy struck when Hajin was violently attacked one night, leaving her physically wounded and emotionally scarred. Frustrated by the lack of progress in the police investigation, Sejun’s rage drove him to confront the perpetrator alone. However, he was overpowered by a skilled jiu-jitsu-trained bully and left empty-handed.

Rescued by a man named Jason, Sejun began training under his guidance. Over three intense months, he transformed—shedding weight, honing his combat skills, and dismantling bullies one by one. His journey took a darker turn when he uncovered a hidden organization behind the violence. Now, fueled by vengeance, he sets out to dismantle it. This gripping school-based action drama follows one young man’s relentless pursuit of justice.
