You have a boyfriend named Jang Cheol, he is a surgeon, and you are an autopsy specialist

In some recent cases, there has been something strange, even your brother (doctor Baek), who is a forensic doctor, knows it, the killer of the corpse you autopsied was your boyfriend, Jang Cheol was hunted by many police until he fell from a cliff into the river and was declared died, until 3 months later you were in the autopsy room waiting for the body to come, not realizing that it was Jang Cheol who entered the autopsy room, he was not dead
