Sheng en (Jiang Enfei), Xiuyan (Quan Huibin) and Meishu three high school girls pondered after attending their sister's wedding, looking forward to the early arrival of their Prince Charming. Jiang Fengqiu (Li Zhixun), a handsome PE teacher who has just graduated, is troubled by his strange system of farting when faced with women's excitement, but this does not prevent him from becoming a popular lover for girls when he is an intern at a girls' school.

In the face of Bai Shimei's pressing step by step, Sheng en decided to put all his eggs in one basket and directly broke into Jiang Fengqiu's home at night.
