Sixteen-year-old Cang Shu is an exemplary student and a beauty, which is why everyone simply assumes she and the school's prince, Cui Xin, are the perfect match. But Cang Shu has no interest in boys, and to quell the pesky rumors, she claims the person she likes is Qi Lin, the student with the worst scores in their grade!

By chance, the high-spirited troublemaker Qi Lin overhears Cang Shu's inadvertent confession and expresses her own romantic feelings. Although Cang Shu could clear the misunderstanding if she wanted to, Qi Lin's genuine eagerness and affection lead her to just request that they remain friends for now. The two girls are polar opposites, yet their differences only make their hearts grow fonder.
