Liu Ze and Wang Tian, two teenagers who have never met each other, were each admitted to Jinshui No. 1 Middle School with the top scores in the city. The calm, introverted, rational Liu Ze; the cheerful young man Wang Tian, who has delicate sensibility. The two have very different personalities, but they are equally matched academically and have become each other's strongest rivals.
In the three years of high school, they went from not knowing each other to tit for tat, from secretly competing to cherishing each other. Liu Ze's rationality was broken by Wang Tian's sensibility, and Wang Tian's looseness was restrained by Liu Ze's rigor. They grew up in competition and gradually discovered the missing parts of each other. The confession that day was silent but deafening. There were only partial differential equations written simultaneously on the whiteboard in the classroom of Class 6. The two ends of the equal sign with wet ink happened to be each other's names, fulfilling the young promise.
Purpose: Youth, competition, anti-school bullying
