Lin Xiaoman, the city's key "perfect score machine", and Jiang Zichuan, the "millennium second best" who is always one point behind her, are the school's default "rivals" - looking at each other coldly before the monthly exam results, overturning the bookshelf when grabbing the same teaching aid in the library, and even competing on whose writing speed is faster when answering questions between classes.
Until a school history project, the two were forced to team up to check old files: they accidentally discovered that the senior academics from 50 years ago also used the method of "score comparison" to hide a "knowledge codebook", and the code was hidden in their current "competition details" (such as Lin Xiaoman's wrong question book annotations, Jiang Zichuan's draft paper formula).
From "fighting for first place" to "decrypting together", they broke through each other's "pretense" while going through old textbooks and working in old laboratories: Lin Xiaoman originally collected wrong questions to help poor students at the same table, and Jiang Zichuan deliberately took second place because he was afraid that the competition would take up time to read unpopular history.
This war that started with "score competition" eventually became the growth of "using knowledge to break down ambiguity and competition to form peers" - it turns out that the best "number one" is when someone helps you turn test papers into love letters and turn knowledge points into stories.
Purpose: Two top students go from fighting over scores to understanding each other, breaking the stereotype of "top students only taking exams", deciphering school history together, turning competition into a driving force for growth, and finally harvesting love that goes both ways, telling us that the friction of competition can also help people become better selves.
