At the class reunion after graduation, Lin Xiaoxing watched Jiang Yi, who was once out of reach, become the center of attention, and realized belatedly that her entire youth had been wandering in the maze of secret love. An accident brought her back to the first day of her freshman year of high school. The slogan "1095 Days to the College Entrance Examination" on the back wall of the classroom stung her eyes. This time, she tightened her schoolbag strap and secretly made up her mind: she would fill up all the unfinished five-threes in her previous life, hide the love letters she had not dared to hand out, and by the way... Take another look at the glowing boy in the white shirt. Unexpectedly, when she was immersed in studying, Jiang Yi, the aloof academic master, would frequently look sideways. "Classmate, your solution to this question is quite special." "Classmate, you forgot your milk on the basketball court." "Classmate..." Lin Xiaoxing raised her head and met his smiling eyes, and suddenly realized that the secret love that went in both directions was sweeter than the ice soda in the middle of summer. This is a story about rebirth, growth, and two idiots slowly getting closer amidst the chirping of cicadas. It is full of hot memes and warmth, and is a warning for excessive sweetness.
