Tong Hua is a kindergarten teacher, and Li Moshen is the uncle of the naughtiest kid in her class. She was called to complain every day: "Mr. Li, your nephew hit someone again." Li Moshen apologized obediently every time, but she realized something was wrong after many times - every time his nephew got into a fight, it was because someone said bad things about her. This man protected her in the most childish way.
