Childhood friends Wang Huanyu, Wei Xing, Han Shuai, Guo Ting, and Shi Wenke grew up on “Universe Street” in a seaside town. In their senior year of high school, they faced uncertainties about their future. The academically-inclined Wei Xing and Shi Wenke clashed with the low-achieving Wang Huanyu, Han Shuai, and Guo Ting. Despite growing pains and youthful ignorance, they matured together, finding strength in their bonds. Through kinship, friendship, and first loves, they navigated joy and sorrow, discovering their paths and pursuing their dreams with determination.
