Quan Lai (Zhang Guoli) has four beautiful daughters: Quan Fang (Cao Yanyan), Quan Wei (Jiang Xin), Quan Shui (Wang Weiwei) and Quan Ai (Han Dantong). Quan Lai worked hard to raise them, and his only wish is that the four children can find their own happiness in their own lives. However, it does not seem to be a simple thing to realize this simple wish. Quan Fang and her husband's marriage is on the verge of breaking up because of trivial matters in life. Quan Wei falls in love with Du Siyuan (Gao Xin), a single father with a daughter, and finds that being a "stepmother" is not easy. At the same time, Quan Shui and Quan Ai's relationship is not smooth. But Quan Lai is most worried about his twilight love with Huang Mudan. This hard-won relationship is destined to be obstructed and stormy.
