Six years ago, Gu Yanshen separated from his wife, Lin Shuyue, because of a diagnostic report. After their divorce, Lin Shuyue gave birth to twins—a boy and a girl—on her own, running a small shop to raise them. Five years later, the two reunite at a hospital, where Gu Yanshen notices the children resemble him. After many twists and turns, a paternity test confirms the children's parentage, and the truth about the altered diagnostic report from years ago gradually comes to light. Gu Yanshen makes every effort to make amends, and the two resolve the emotional wounds of the past and find their way back to each other. The family finally begins a happy life together.
