The September wind carries the fragrance of sweet-scented osmanthus and quietly sneaks into the reading area on the third floor of A University Library. Su Wan ran her fingertips across the yellowed pages of "History of Western Philosophy" and suddenly heard the sound of paper rustling behind her. When she turned her head, she saw the boy's knuckled hand pressing on the notebook she had left behind. The setting sun penetrated through the blinds, cutting out a mixture of light and dark on his angular profile. This unexpected encounter, like a pebble thrown into a calm lake, created ripples in Su Wan's seemingly regular university life. When Lin Xi, a passionate club senior, and Gu Zhi, the gentle captain of the debate team, appeared one after another, the destinies of the four young people began to intertwine. They shared songs on their headphones on the sun-drenched boulevard, argued over a high-level math question in the late-night study room, and exchanged long-hidden thoughts on the snowy playground. Love is like the undefeated camphor tree in A University. It takes root and grows amidst misunderstandings and reconciliations. However, it is also faced with the difficult choice between reality and ideals at the crossroads of graduation season.
