Car repair technician Xia Libin (Lei Jiayin) was forced by his future mother-in-law to buy a house before getting married. Bai Ping and his lover Wei Lan from the same company planned to get married secretly, so they planned to buy a two-bedroom apartment with Xia Libin and repay the loan together. Xu Zilin (Yuan Shanshan), a reporter for an entertainment newspaper, accidentally guest-starred on a blind date show and was promoted by the editor-in-chief to become the editor-in-chief of a column that picks on men. Because her extreme views led to the failure of Xia Libin's "attack" on the prospective mother-in-law, Xia Libin launched a counterattack against Xu Zilin, but in the process, the happy enemies came together. At the same time, Bai Ping and Wei Lan also faced their own troubles: this pair of young people who had just entered the marriage hall after two years of love had to carry out a long-lasting underground love affair because the company did not allow love. Unexpectedly, various misunderstandings and conflicts between the two families followed and escalated. Although various contradictions, pressures and changes emerged one after another, the four young people began to understand each other between friendship and family affection, and gradually matured.
