Liang Zhiyue accidentally suffered a brain injury and mistook Zhou Hansheng, an upstart in science and technology, for her husband. His elder brother Liang Zhiyan paid a lot of money to ask Zhou Hansheng to pretend to be his lover to appease his sister. Zhou Hansheng, who was forced to do business, closely guarded his true feelings while cooperating with the performance, but he fell in love with the active and enthusiastic Liang Zhiyue while getting along day and night. Unexpectedly, Liang Zhiyue recovered and regained her memory, instantly changed back to her cold appearance, and deliberately drew a clear line with him. Zhou Hansheng was moved and was unwilling to be "abandoned", so he transformed into a clingy suitor and pursued her step by step. Liang Zhiyue felt guilty and repeatedly gave in. In the end, the two broke through their false identities and came together.
