Beneath the pagoda trees at summer's end, the setting sun spreads across the sky. Three first-year high school girls each hide a love they cannot put into words.
Yan Wanxia falls for the young teacher Ouyang Jingzhan at first sight, her feelings fervent and obsessive. As her gaze follows him everywhere, Jiang Muye's sudden kiss crashes into her world. The two secret affections pull her back and forth; obsession disrupts her studies, while jealousy and hurt roil day and night. They nearly cross the line, leaving only ashes after the flames burn out.
Mo Sangyu also falls for Ouyang Jingzhan, but knows clearly that there can be no future between teacher and student, so she quietly locks away her feelings. Watching her friend sink deeper, she worries that rumors might affect the teacher. She briefly develops a fondness for her classmate Fu Hong, but it quietly blooms and ultimately fades into something ordinary.
Baili Juyi, sensitive and starved for affection, grows attached to the gentle Pei Qiugui. Beneath the office lamp after evening study, she uses questions as an excuse to savor a few moments in his company, carefully treasuring this secret attachment. Only when Pei Qiugui becomes engaged does she put her feelings away, bury them in her books, and turn them into the strength to keep moving forward.
Between corridors, sunsets, desk lamps, and textbooks, three unspoken crushes burn with sincerity and intensity. The first stirrings of young love are a fire lit in haste: passionate and real, but born at the wrong time.
One is consumed by a blaze, one lets her faint light fade, and one hides her feelings and gathers strength.
The flowers never bloom, yet the fires in their hearts remain. Carrying their longing, struggles, and regrets, they slowly grow up amid the chaos of their first year of high school.
