Song Qinghuan, a "crazy" girl with excellent grades and a hot temper, was forced to make up lessons for Gu Yan, a bad student due to teacher arrangements. In the early days, the two had a tit-for-tat confrontation over their learning attitudes. Song Qinghuan went "crazy" and yelled at others, blocking his game account and forcing him to study. Gu Yan resisted on the surface but was secretly worried. When Song Qinghuan was being challenged by classmate Zhao Ya, Gu Yan went "crazy" for the first time to defend himself, expose the conspiracy and declare his sovereignty, and the relationship between the two heated up. Song Qinghuan gradually showed her gentle side to urge Gu Yan, and Gu Yan was determined to counterattack in order to get admitted to the same university as her. The two worked together to fight against obstacles amidst mutual hostility and affection, and finally went in both directions, achieving dual growth in academics and love.
