Chen Xu and Shen Qingyue were once the lovers that everyone envied, from their school uniforms to their wedding dresses. However, the trivialities of married life, the pressure of work, the involvement of both families, and the lack of effective communication caused their relationship to be exhausted by internal friction day after day. They chose to divorce in the most "honorable" way. After the divorce, the two lived on their own tracks. They thought they had gained freedom and relief, but through chance intersections, they re-examined the past and saw each other's unspeakable dedication and pain. In the face of new crises, they once again became each other's most solid support.
