A Sense of Amusement

Vice Chairman Lee Myeong-jun of the Hyeondo Group, devastated by the loss of his daughter to school bullies, adopts Yoon Gar-ram, a psychopathic defector from North Korea, with one goal in mind—revenge. Gar-ram, a product of North Korea's brutal drug experiments, is a sadistic weapon who slaughtered everyone in the research facility before escaping to South Korea. After her release from a juvenile detention center, she enrolls in school with a dual purpose: to exact revenge on her adoptive father and to indulge in her own twisted desire for hunting those who wronged her.
