A new transfer student arrives in Kang Hyunbeom’s class—who also happens to be the school’s head of discipline. From the moment he walks in, the transfer student gives off a dangerous vibe. He’s none other than Ban Taehyun, the delinquent at the center of a gang fight Hyunbeom’s friend witnessed. Driven by his sense of duty as a disciplinary officer, Hyunbeom starts keeping a close watch on Taehyun. But as they continue to interact, the two slowly grow closer. Seeing this as a chance, Hyunbeom sets out to reform Taehyun into a model student.
However, the closer Hyunbeom gets… the more Taehyun’s heart begins to drift in a different direction.
Can this delinquent really be reformed without incident?
