Yeon-jin hears about the death of her ex-boyfriend, Jung-hoon. Jung-hoon's flirt partner and girlfriend, Mi-ji, comes to her house. She knows that Mi-ji is suffering from Jeong-hoon, who has become an evil spirit, and decides to help her. She tries to exorcise him with all kind of beliefs, but Jung-hoon, who has become a powerful evil spirit, refuses to leave.

Dating violence is both emotional and physical violence that occurs in secret. It is widespread, and as a result, deaths and murders flood the news. I wanted to convey these social problems in a pleasant but heavy way.
