Shen Wantang ends her three-year marriage to Fu Jingchuan, gives up all claims to their marital property, and takes her twin sons abroad to start a new life at a friend's guesthouse. Fu Jingchuan initially believes their separation is merely a temporary act of anger, but gradually comes to recognize his past coldness and misunderstandings. As the children's true identities are revealed, he learns that the twins are the children left behind by his late younger brother, Fu Jingheng, and finally understands how much responsibility Shen Wantang has shouldered alone over the years. Faced with his belated apologies, Shen Wantang chooses to let go of the past but does not return to their former marriage. In the end, the two protect the children together as family, letting go of their lingering attachments through understanding and respect, and each moves on to a new life.
