Description：The hidden divorce fact, which was triggered by a curatorial report by her boyfriend Chen Fang, made Nanfei besieged by public opinion as a "mistress". Moreover, due to Chen Fang's dilemma between family responsibilities and lover status, Nanfei unilaterally proposed to break up and went to Shanghai to seek refuge with her best friend Qi Jiayi, who was about to get married. Unexpectedly, she ran into her best friend Qi Jiayi who was regretting her marriage at the last minute. After helping her "get out of the predicament" of her short marriage, the two jointly bought a house and formed a best friend alliance. In order to avoid their parents' urging to get married, under Qi Jiayi's "matchmaking", Jiao Yue, a neighbor who returned from Wall Street and suffers from depression, and Nanfei formed a temporary fake couple. Unexpectedly, the parents of both parties who were kept in the dark took turns to force the marriage battle. Chen Fang, who was chasing love thousands of miles away without knowing the truth, and Ling Jiaoyang, who regarded himself as a male best friend but actually had a crush on Nanfei for many years, also turned enemies into friends and jointly launched a "scumbag identification" operation against Jiao Yue, which triggered a series of ridiculous misunderstandings.
