Zhou Xu runs an anonymous love answering account, specializing in solving relationship problems for college students. One day, a girl named "Go to bed late and it will rain" came to him and asked him for a fee how to pursue a boy who seemed gentle but was actually emotionally insensitive. Zhou Xu carefully formulated a strategy for her, but the next day, the school beauty Shen Zhiyao, who had always been cold and distant, started to do everything in the strategy to him. Creating chance encounters, testing preferences, quietly intervening in his life... Zhou Xu gradually realized that the person the girl wanted to pursue might be him. But what really made him uneasy was that Shen Zhiyao knew from the beginning that the person behind the account was him. In the abandoned auditorium, she put her phone in front of Zhou Xu and smiled softly and quietly: "Classmate Zhou, since you wrote the guide, how are you going to teach me and make you mine?"
