The simple and beautiful Li Er (played by Chen Duling) is deaf in her left ear and cannot hear any sound. However, the physical defect did not make her feel inferior. On the contrary, her personality is gentle and gentle. By chance, Li Er met a girl named Bala (played by Ma Sichun). Bala's personality is completely opposite to Li Er. She is unrestrained, unruly, and yearns for a free life. In Bala, Li Er saw the rebellious and persistent side of his heart. What Li Er did not expect was that Bala actually got together with Xu Yi (played by Yang Yang), a boy he had always secretly loved, which made Li Er begin to experience the cruelty of youth. However, Bala actually liked a boy named Zhang Yang (played by Ou Hao) in her heart. Fate made their love a tragedy and eventually took away Bala's young life. This accident made several ignorant children quickly transform and grow up, blooming the most gorgeous and desperate flower of youth.
