Overview:Three men are thrown together by a toddler who comes out of nowhere, disrupting their already stressful lives. The loyal and kind-hearted Gao Han (Bosco Wong) has just lost his legal battle with his ex-wife for custody of their daughter. His ex-girlfriend and first love, Guan Lingling (Shirley Dai), who died in a car accident, has just sent her son to live with him. Gao Han and his two tenants Wang Dongyang (Liu Guanxiang) and Yu Bo (Luo Yunxi) suddenly find themselves becoming nannies to a child, Dudu (Zou Zichen). Not only must they look after this little one, they must deal with an even bigger headache- Dudu's aunt Guan Shanshan (Kan Qingzi). While the three grown men busy themselves with raising Dudu, they try to determine the child’s paternity. They undergo a custody battle, as they deal with issues tied in with the return of Han's ex-wife’s Liu Min (Mai Hongmei). Han and Shanshan develop feelings for one an other. To complicate matters, Yu Bo also falls for Shanshan.
