In the golden autumn of 2012, the bell rang for the 50th anniversary of Qinghe Middle School. After ten years of absence, 32-year-old Su Nian, Lin Yu, Chen Hao, Xu Wei, and Lu Yang - five souls who had left a profound mark on their youth in the small town, followed the call of the school anniversary and returned. Su Nian, a calm and self-possessed civil servant from the Education Bureau, has an unknown softness hidden under his black-rimmed glasses; Lin Yu, a gentle and elegant professor at a double first-class university, has an unspoken persistence behind the perfect appearance; Chen Hao, a smooth and shrewd porcelain man The manager of the Brick Company, who attaches great importance to love and justice but cannot hide the nostalgia in his heart; Xu Wei, a bright and lively theater actor, has a lively chatty soul under the cold mask; Lu Yang, a sunny and pragmatic foreign trade translator, whose innocent heart has never been smoothed away by the years. Returning to a campus with a new look but old shadows everywhere, the lush years from 1999 to 2002, intertwined with sweat, laughter, secret love and family pain, swept away like a tide. The unspoken confessions and unresolved misunderstandings quietly awakened in the delicate atmosphere of reunion. Facing the reality and confusion of their thirties, can they muster the courage to write a new chapter for the "unfinished tense" of youth under the reflection of the old time? A nostalgic feast about the pain of growing up, the gift of time and the possibility of love begins here.
