Four-year-old Gu Nuannuan takes a "finding mom" notebook and sets her sights on truck driver Zhou Chunmei. Divorced with a child, Zhou Chunmei is independent and pragmatic. Nuannuan's father, Gu Chengchuan, is actually the chairman of Gu Group, but disguises himself as an ordinary employee making 4,800 yuan a month to test her. Zhou Chunmei doesn't mind his poverty and teaches him how to live frugally. After interference from her ex-husband, greedy demolition-seeking sister-in-law, and a security guard leak, the back-alley demolition compensation of 3.86 million yuan ultimately goes to Zhou Chunmei, and Zhao Haifeng is investigated. Gu Chengchuan confesses his true identity; Zhou Chunmei, though irritated by his concealment, accepts it, and they register their marriage to become a family of four.
