A single mother, Lin Qianqian, plans to enter into a marriage of convenience with a local man so she can register her son's household.
Gu Yan, the head of a powerful group, also goes to the civil affairs bureau to arrange a marriage of convenience in order to fulfill an elder's dying wish. The two unexpectedly meet there. Mistaking Gu Yan for the man she was supposed to marry, Lin Qianqian impulsively marries him.
Unbeknownst to them, the two had crossed paths six years earlier, and Lele, Lin Qianqian's son, is actually their child. After the wedding, Gu Yan quietly protects the mother and son, secretly helping her deal with one problem after another.
