Lai Dui Dui is a young college student who dreams of becoming a successful artist. However, she has little talent or ability when it comes to other subjects: she hates math, English and other issues and it is reflected in her horrible rankings. She is in serious danger of falling if she does not do something about her studies. Attending the same college is Jiang Zuo, an A-level student who has no friends when it comes to all things academic. The two actually crossed the street before high school. But due to the conflict of prosopagnosia (a condition that means Lai Dui Dui can not recognize the face), she could not remember that he was No one. Jiang Zuo is trying to escape the attention of his wealthy ex-girlfriend, so he agrees to help Lai Dui Dui if she pretends to be his girlfriend. She agrees, but the decision has had countless consequences. It turns out that Jiang Zuo used to have feelings for Lai Dui Dui and that these feelings may come back by spending more time with her.
