Qi Moyan, a cold serial killer and a perverted murderer × gentle and cold forensic doctor Gu Mengyan
The two had known each other since they were children, but due to some reasons they were separated for 3 years. When they met again, they had changed, especially Qi Moyan, who had changed the most and turned into a cold-hearted, ruthless and emotionless murderer. But when she met Gu Mengyan, her dark world had a light. It can be said that Qi Moyan has liked her since she was a child. Qi Moyan loves Gu Mengyan very much and is not willing to let her get hurt. People she hates will help her solve it. She is extremely gentle to Gu Mengyan. He is even willing to dedicate his heart to her, but if Gu Mengyan wants to leave Qi Moyan, he will threaten her but will never hurt her, but Gu Mengyan cannot accept such love and makes her feel suffocated.
Later, the two went to Germany (a country where same-sex marriage is allowed) to be together, and they were together forever.
