Yufen (Ai Jing)'s cousin Li Ping (Ning Jing) is a primary school teacher. The "Dashuai Migrant Children's School" established by Ma Dashuai (Zhao Benshan) is about to be demolished. With the help of freelance writer Wang Bin (Wang Ping), the school is finally saved. Not only that, Li Ping also switched jobs and became a teacher in the school. Due to Wang Bin's exaggerated publicity, the outside world misunderstood that Ma Dashuai's school was free and open. For a time, the school was overcrowded and the expenses increased sharply. In order to maintain the operation of the school, Ma Dashuai almost exhausted all his financial resources, and conflicts arose between Yufen and Ma Dashuai. Fan Debiao (Fan Wei) also ran away from home after a big fight with Guiying (Gao Ming'e) and came to work in Ma Dashuai's school cafeteria. Yufen is pregnant. The father of the child is her ex-husband Niu Er. After the abortion, Fan Debiao has been taking care of her carefully and keeping this secret for her. Unexpectedly, it caused Ma Dashuai, who accidentally witnessed this scene, to misunderstand.
