Xu Lai is a DINK who hates children the most. God played a joke on him and made him the guardian of five children - his brother died in a car accident, his sister-in-law ran away, leaving three children behind, and the neighbor next door was poisoned by gas, leaving two children behind. Five children were crowded into his 60-square-meter rental house, crying and making noises. Jiang Yu is a community worker responsible for monitoring whether he abuses children. She comes three times a week, and every time she comes she sees a different "tragic situation." Six months later, not only were the five children not sent away, they also learned to cook, clean the house, and take care of each other. Jiang Yu asked him: "How did you do it?" Xu Lai said: "I didn't do anything. They taught me what responsibility is."
