On the first day of her freshman year, Cheng Shishi saw a boy on the playground. He was wearing a camouflage uniform with a low brim and walked slowly and slowly, as if the whole world was moving at his own pace. She didn't know his name, she didn't know which college he was from, and she didn't know that he would become the most important person in her four years of college. All she knew was that her heartbeat was beating half a beat faster.
Li Mu never felt that college was anything special until he bumped into a flustered girl under the ginkgo tree. She bumped into him, spilled the water, blushed and said sorry. He remembered her name - Cheng Shishi.
From the playground to the library, from the poetry conference to under the cherry blossom trees, from "what a coincidence" to "see you tomorrow", they slowly, clumsily and cautiously approached each other on the days when the maple leaves in A University turned red, green, and green again. Campus story, two top students, secret love comes true, from school uniforms to wedding dresses. This is a story about waiting and certainty. All the waiting is for that sentence - "I like you, starting in September last year. Earlier than you."
