Li Siming, a 32-year-old Internet project director, is a decisive fire-fighting captain in the industry. He only relies on logic and does not talk about emotions in his actions. While his wife was on a business trip, he used the project process to plan the daily routine of raising the baby, but he repeatedly failed. The five-year-old daughter Zi Meng is particularly precocious and sensible, and she takes care of him in turn. It wasn't until he saw his daughter's graffiti diary that he realized that the child's well-behavedness was the armor that protected the family. It was his daughter who had been secretly healing and raising his clumsy father.
