An ordinary high school life record, Li Mumu, who has excellent grades but never likes to do homework, is still the most troublesome student of class teacher Luo at the beginning of his second year of high school. She looks like a good girl, but she is actually righteous, playful, and unwilling to be trapped by the rules; the transfer student Chen Ye breaks into Class 3 with a rebellious spirit, and also breaks into her originally lively but stable life. From the No. 71 Bus after evening self-study, to the wind beside the playground, to the radio station, report cards, and the moments when they were called on by the teacher again and again, Li Mumu and Chen gradually became people who can share secrets and bear their emotions from competing with each other and testing each other. At the same time, Lin Yu, who had an ambiguous relationship with Li Mumu, also left a real and restrained regret during this period of youth.
