At the beginning of the second year of high school, transfer student Su Wanxing had just entered Xinghua Middle School. She formed a "liangzi" with Lu Zhaoyan, the top grader and the ace of the basketball club - she accidentally stepped on his basketball shoes engraved with the date of his championship. What was originally thought to be a start of incompatibility, gradually breaks down through unexpected intersections: Su Wanxing helps Lu Zhaoyan tutor Chinese in partial subjects, and Lu Zhaoyan steps forward when she is pestered by gangsters. The two share headphones in the playground after evening self-study, and secretly pass hand warmers in the corner of the library. When a young love quietly grew, it was met with a "score warning" from Lu Zhaoyan's mother, and Su Wanxing's hidden secret of "re-reading as an art student" was unexpectedly exposed. Should you choose to suppress your emotions and focus on your studies, or should you choose to fight against obstacles side by side? When the summer night wind blows through the hair of young girls, they will eventually understand that the best youth is to run towards the light with the person you like.
