Su Jinxi is recognized as a "question-answering machine" in the second grade of high school. She cares about almost nothing in life except grade ranking. Transfer student Lu Chenyi parachuted to the table next to her, with a cold face, but he always handed her a bottle of warm soy milk while she was doing her homework. Su Jinxi thought he was aloof and taciturn, until one day she saw him squatting in the corner of the playground, feeding stray cats, mumbling words; she thought he was careless, but every time the exam rankings were announced, his name was always behind hers. A campus tug-of-war about grades, heartbeat, and "you have to rely on your ability to be a classmate" quietly unfolded - who said top students don't know sweet things, but their likes are all written in the improved transcripts and secretly exchanged correction books.
