The story revolves around five high school students who accidentally come together in the same urban key high school. Lin Xiran's rigor and Gao Yaolin's persistence, Xia Zhiyin's aloofness and Du Xinyan's free and easy, and Zhou Yuchen's acumen all work together to weave a complex network of relationships. Under the interactive advancement of the five main lines of study, friendship, love, family and dreams, the characters experience conflicts, misunderstandings, mutual support and self-awakening: there is the collision of performance anxiety and life confusion, the struggle between parents' expectations and the true self, the emotional entanglement ranging from friendship to secret love, the collapse and reshaping of secret exposure, and the brave restart of dreams after their dreams are torn apart by reality. The three volumes switch between multiple perspectives, showing the pain, humor, warmth and pain of growing up. In the end, the five people each move towards a new life, but they leave an indelible mark on each other in their youth.
