The fact of a hidden divorce, triggered by a curatorial report by her boyfriend Chen Fang, has led to Nan Fei being heavily criticized by the "mistress" public opinion. Furthermore, due to Chen Fang's dilemma between family responsibilities and the status of a lover, Nan Fei unilaterally proposed to break up and seek refuge with her close friend Qi Jiayi in Shanghai. Unexpectedly, she met her friend Qi Jiayi, who was about to get married, and helped her "get out of the trap" after a brief marriage. The two of them jointly bought a house and formed a best friend alliance. In order to avoid being pressured by their parents to get married, Jiao Yue, a Wall Street returnee neighbor suffering from depression, and Nan Fei formed a temporary fake couple under Qi Jiayi's "husband pairing". Unexpectedly, the parents of both sides, who were kept in the dark, took turns to engage in a forced marriage war. Chen Fang, who was chasing after his love for thousands of miles without knowing the truth, and Ling Jiaoyang, who claimed to be his male best friend but had secretly loved Nan Fei for many years, also turned enemies into friends and joined forces to launch a "scum detection" operation against Jiao Yue, which triggered a series of ridiculous misunderstandings.
