Two male protagonists + two strong men + HE + solving crimes + emotional pull
One is the criminal investigation captain who puts physical evidence first, and the other is a criminal psychological consultant who has insight into people's hearts. The two people with conflicting concepts in handling cases were forced to form a team because of a serial murder case. They went from tit-for-tat to mutual recognition.
