As the school year begins and plane tree leaves fall, Lin Weixi, a freshman in the Chinese department, bravely steps into an unfamiliar campus. An accidental spill of milk tea brings her face-to-face with the cool, gentle gaze of Jiang Yiqing, a top student in the computer science department. At the class meeting that follows, sunny campus heartthrob Shen Haoyu, brimming with energy, becomes the first ray of warmth in her college life.
One is a programming prodigy who seems cold but is warm inside, expressing his deep affection through silent devotion: the name captured in a dazzling light show, his patient explanations in the library late at night, and the long journey he makes to be by her side when she's sick. Every detail conceals a tenderness no one else sees. The other is a passionate journalism student who expresses his sincerity with openness and determination: a hot breakfast in the morning, rushing around to care for her when she's hurt, and a guitar serenade when he confesses his love. Every gesture carries his heartfelt sincerity.
Their companionship during midterms, their protection through winter, the flutter of spring field trips, and the choice brought by a midsummer confession: over four years of youth, the two young men leave indelible marks on her life in their own ways. Will she choose a steady love beneath the cool moonlight, or lean toward a passionate romance beneath the blazing sun? This contest of love and growing up will finally find its answer in the season when the plane trees flourish, an answer that belongs to them.
