The heroine Su Wan is a "confused academic master" in the Chinese Department from a small southern town. She loves hanging out in the library, writing short essays, and occasionally makes mistakes (such as picking up the wrong books, memorizing the wrong class schedule); the male protagonist Lu Jiaoyang is the "iceberg academic god" of the computer department. He has won numerous competitions. He looks cold and talkative, but is actually careful and restrained, hiding an unknown tenderness. The story revolves around the two people's four-year campus life from the beginning of their freshman year to their senior year. It focuses on "slow-burning heartbeat, two-way healing, and daily sweet love". It is free of sadomasochism and focuses on pure feelings and common growth in youth.
