Seven days before the wedding, Xu Nian announced a half-year postponement of the wedding without discussion, assuming that Zhou Yu, who had been in love for nine years, would wait for her as always. But this time, Zhou Yu chose to let go and start a brand new life with Su Wan. Until the wedding was held as scheduled, Xu Nian realized that past tolerance did not mean having no bottom line. As her career met one test after another, she began to re-examine her choices. Facing the missed relationship and the brand new life, the three of them gradually understood that true love requires respect, communication, and shared responsibility amidst regret and growth.
