At the beginning of her second year of high school, Su Wanwan, an "art geek" with a severe partiality for subjects, was put into a special training class for top students by her class teacher. She also accidentally became the classmate of the cool and taciturn Lu Xingchen, who was number one in the grade. One is a "little confused" who hides romance in his drawing paper and always catches up on sleep in class, and the other is a "student god" whose notebook is full of formulas and is stingy even in laughter. The two people who should have had nothing to do with each other are bound by accidents: Su Wanwan's wrong sketch book contains the problem-solving steps of the academic god, Lu Xingchen's cold thermos cup is secretly replaced with hot milk tea, under the shared umbrella on a rainy day, the sound of the heartbeat drowns out the sound of the rain. When the art entrance examination meets the academic sprint, when the girl's secret love breaks through the teenager's thoughts hidden behind the scratch paper, they finally understand: the best student era is when the summer night wind blows, and when I run towards you, I happen to hit the scorching sun in your eyes.
