Choi Seunghyun, a male who is suffering from paranoid schizophrenia, must go to his weekly group therapy session with his psychologist and others who are having various issues in their lives. This session was different. His normal psychologist wasn't leading the group. A male with the name Kwon Jiyong had taken over the sessions. Seunghyun was unsure if he liked this new psychologist, but it would all change over time.
