Emiya is an ordinary forensic doctor, but he is mentally unhealthy and has an antisocial personality, but he is undoubtedly a genius. Criminal genius. He and Amakusa are classmates and best friends, although one became a policeman and the other became a forensic doctor. Took a completely different path. Amakusa knew that Emiya had dated a man when he was a student, but it seemed that they broke up in the end. And in a murder case, they met the person involved who was Emiya's ex. What was this really talking about? Amakusa tricked Emiya into examining the body in order to show what kind of expression Emiya would have when he saw them? What happens is that the truth is for the good. It's just that after they met, Emiya showed no expression except for some surprises when he came again. I thought there would be an emotional drama. But it seemed that the other party's expression was not so calm after seeing Emiya. Emiya looked angry and wanted to leave as quickly as possible. It just seems like bad luck. Because it happened to rain heavily and the road was blocked.
