Plot

To pay off her father's debts, Qin Zhiai accepted to impersonate the female celebrity Liang Doukou, who recently announced her engagement to Gu Yusheng, Qin Zhiai's high school crush. To fulfill her job, Qin Zhiai moves in with Gu Yusheng and gives him all of her firsts. However, she only receives his disdain—as far as he knows, she is the despicable Liang Doukou, the woman who forced him to marry her. Furthermore, Qin Zhiai realizes that Gu Yusheng might have forgotten their time together as students. While Qin Zhiai is suffering from heartbreak, Gu Yusheng discovers that he seems to have lost an important part of his memory—a fragment that is suspiciously Qin Zhiai-shaped.
