During Lin Xia's tortuous high school career, she formed an "unreliable clique" with Zhang Rui, Xu Anran, and Ye Zhiqiu. They experienced campus elections, exams, club farces, family conflicts and youthful crushes, and gradually understood each other and grew up amidst constant conflicts and misunderstandings. Lin Xia and Xu Anran's acquaintance, understanding, and mutual healing also unfolded in the growth team. The appearance of Song Jianan plunged Lin Xia into an emotional maze, and the boundaries between friendship and love gradually blurred. In three years, everyone went their separate ways under the test of parting, dreams and friendship. The regrets of the past became witnesses of growth. Finally, in the graduation season, they harvested the true meaning of youth and relief.
