Se-Jun, a self-assured food enthusiast with a robust build, is immune to fat-shaming due to his strong-willed personality. He has only one friend, Seo Ha-Jin, who has been practicing Jiujitsu since childhood to protect him. One day, Se-Jun encounters a classmate thug, and Ha-Jin comes to his rescue, defeating the delinquent handily. However, the same night, Ha-Jin is discovered severely injured, with a grievous knee injury and psychological trauma. Despite Se-Jun’s efforts to seek justice, the investigation drags on, prompting Se-Jun to seek revenge, but fails against the skilled Jiujitsu master.
Fortunately, Jason intervenes and trains Se-Jun in Jiujitsu, which helps him shed weight and gain self-confidence. After three months of intensive training, Se-Jun comes to the realization that a secretive group is involved in the attack and decides to dismantle them with his newfound skills. This high-stakes drama revolves around Se-Jun’s quest for vengeance against his tormentors.
