In his second year of high school, Gu Chen "accidentally" got involved in various misunderstandings between transfer student Xu Ran and top student Lin Ziyou, which triggered a series of campus turmoil. The naughty Zhang Litong, the enthusiastic Zhao Shiting, and the silent Qiu Ming each participated with their own worries. They compete with each other, laugh at each other, and support each other in the examination room, the stadium, clubs and parent-teacher meetings. The confusion of youth, the fragments of friendship, the pursuit of dreams and hazy emotions are intertwined in this chaotic and lively youth time. After experiencing setbacks, farewells and growth, everyone has completed their own epiphany and transformation. This is a youth rhapsody that bravely "grows up" in laughter and tears.
