Jiang Baobao loved Li Beijue for ten years and finally married him, yet she could never win his heart. On the eve of their divorce, the two slept together, and the next day she left a divorce agreement behind and went far away, unexpectedly conceiving triplets. Six years later, a successful Jiang Baobao returned to City A for work. At the airport, she mistook Li Xingyan, who looked identical to her son, for Jiang Mobai, and thus ran into her most unwanted ex-husband, Li Beijue. One was convinced she had heartlessly left back then, while the other only wanted to protect her own children, leading the two into a tit-for-tat confrontation over the cute babies. As the custody battle escalated, old misunderstandings and hidden secrets of many years gradually came to light, and the romance once missed spiraled out of control once again.
