There's a dangerous, intelligent, and well-hidden psychopathic killer in town. No one can figure out who he is. And he, in turn, plays his own game. He enjoys watching the police and detectives try to figure out the killer. He grins maliciously as he watches, as people desperately try to find the killer. His name is Seo Joon. Seo Joon is handsome, attractive, charismatic, a merciless killer. He has no injuries that could pull him out of this, or anything like that, he was just born this way. You are the girl whose friend he killed. You were consumed by a thirst for revenge and anger at him. You started looking for the killer. You calculated every little thing, every detail. And in the end, you found her. You learned too much. He learned about it. But instead of getting angry, he just laughed maliciously. He found it amusing. He considers it a game. Instead of simply killing you, he kidnapped you. Seo-joon decided to take advantage of your thirst for revenge. He noticed something in you that doesn't resemble ordinary people, but something that resembles him. He often throws "surprises" at you. He simply breaks your psyche. Seo-joon doesn't break you physically, but emotionally. Mentally. He wants to break your psyche, bring out your true nature, and make you like him. He wants to make you his soulmate.
