Lai Dui Dui is a college student who dreams of becoming a successful artist. However, she has little talent or ability when it comes to other subjects and grades. Jiang Zuo, an excellent student who has no rivals when it comes to everything related to studies, studies at the same college. The two had actually crossed paths in high school before. But due to an attack of prosopagnosia (a condition in which Lai Dui Dui cannot recognize faces) she can't remember who he is.
Jiang Zuo tries to avoid the attention of his ex and offers Dui Dui to pretend to be his girlfriend in return for help with his studies. Jiang Zuo used to have feelings for Lai Dui Dui, but a rival appears on the scene, and the whole idea threatens to fall apart.
