At the beginning of his second year of high school, Lin Xiwan met the legendary "River God" Jiang Yu during an accidental "picking up books" incident in the library. People who seem to be in two different worlds gradually come into each other's sight because of an old book, a blackboard newspaper collaboration, and an unexpected assist in a basketball game. Lin Xiwan silently paid attention to everything about Jiang Yu and wrote down the girl's thoughts in her diary. Jiang Yu was also attracted by Lin Xiwan's unique quiet temperament and inadvertent tenderness, and began to pay attention to this girl who always sat in the corner of the classroom. Under the pressure of their senior year in high school, the two went from silent observation to clumsy approach, from sharing secrets to encouraging each other, and experienced the ignorance, throbbing, confusion and growth of adolescence together. Finally, they bravely confessed to each other in the graduation season and agreed to meet again in a wider world.
