The introverted and quiet Xiao Xi and the cheerful and uninhibited Zi Yan, after experiencing misunderstandings, separations and respective losses in their green years at university, finally ignited a passionate love in an accidental reunion at the skating rink. Every corner of the campus witnessed their sweet cuddles, fierce quarrels and unforgettable vows. Graduation is like a watershed. Ziyan goes south to Shenzhen to work hard, while Xiaoxi returns to the small town in the south of the Yangtze River.
For love, Xiaoxi resolutely went to Shenzhen. However, the reality outside the ivory tower is cold and sharp. Xiaoxi's career is steadily rising, but Ziyan is struggling in the advertising industry, with meager income and lack of planning. The pressure of life, differences in values, lack of communication, as well as Ziyan's increasingly violent temper and Xiaoxi's deep loneliness have eroded away the sweetness of the past bit by bit. Arguments, injuries, separations and reunions form the main theme, and love is exhausted in the quagmire of reality.
When Xiaoxi faced a job transfer and needed to solve the household registration problem, a ridiculous and sad proposal was born: marriage by agreement. With their own unfulfilled wishes (Xiao Xi regarded marriage as the end of youthful feelings, Zi Yan regarded it as some kind of compensation), they hurriedly received the certificate before getting off work at the Civil Affairs Bureau. There is no sweetness, only silence and alienation. The symbolic "wedding banquet" ended hastily at KFC, and Ziyan left in a hurry on their wedding night. This relationship, which began as pure love, ended with a one-year, non-interference contractual marriage. A year later, when they walked out of that alley again, holding the bright red divorce certificate in their hands, Xiaoxi's tears fell silently, saying goodbye to the youthful love that had gone from innocence and passion to exhaustion and desolation.
