The clinical psychology department where Ji Zhao works has a special patient, Chang Yu. He has several seemingly unrelated labels such as "rich second generation, criminal policeman, and multiple personalities." What's even weirder is that he claims to have known Ji Zhao since he was a child. Ji Zhao, who has no memory of this, only regards him as a good opportunity to study typical psychological cases.
As the "Double Brain Interconnection" treatment progressed, Ji Zhao entered his subconscious again and again to search for the cause of his split personality, and unexpectedly peeped into an accident many years ago. In that nightmare, there were her lost memories and a broken him.
