A forensic doctor, a policeman, and a newly graduated police officer met a junior forensic doctor because of a murder case, and they were still studying as junior forensic doctors with their masters. By chance, their souls exchanged and they fell in love with each other. "I didn't expect that the first corpse I asked to dissect was you." No one will ever know the soul of the policeman's body. In fact, it was the police officer who died, but his soul was that of the junior forensic doctor, and the junior forensic doctor wore the body of the junior forensic doctor. The policeman's soul can only live alone.
