The male protagonist is an urban emotional counselor, specializing in "big data metaphysics"-style marriage and love matching, specializing in solving difficult divorce cases. After receiving an "impossible" task - to help the most difficult female CEO in the city find love, he found that all data calculations could not point to a perfect match other than himself. Just when he wanted to give up quietly, the system's punishment mechanism and the female CEO's pressing pressure forced him to play the role of "shadow boyfriend". In the process of helping her drive away all kinds of scumbags, he gradually became the most perfect person in her heart. This is an urban emotional comedy in which an "emotional mentor" is eventually tricked by his own "client".
