On the day of the wedding, Lin Zeyu leaves the bride Ye Xiwei behind for his childhood sweetheart Xu Tiantian, making her switch cars, deliver a gown, and postpone the ceremony. Calmly canceling the wedding, Ye Xiwei contacts Xie Yunchun, a suitor she rejected three years ago, to save the day. Xie Yunchun expresses willingness to pick her up, but also lets her know she can choose not to marry. When Lin Zeyu later tries to reconcile and is refused, Ye Xiwei and Xie Yunchun establish an agreement of equal communication as they get along, stepping steadily toward a new life.
