Intern Zhong Yu and Lingyue CEO Qiao Qingwu have zero intersection. According to the trajectory of fate, eight years later they will form a family and give birth to a daughter named Suisui. Five-year-old daughter Suisui unexpectedly travels back to the present, brings out evidence to prove the blood relation, and is forced to live together for the convenience of taking care of the child. Playing a married couple externally while disliking each other, the two fall in love under Suisui's assistance and repeated interactions, jointly dealing with wealthy rotten relatives, resolving romantic rivals' entanglements, and even preemptively avoiding the future tragedy of grandfather's passing. Ultimately letting go of the idea of resisting the future, they willingly come together, living happily as a family of three.
