Seventeen-year-old Zhang Qiao is an inconspicuous "invisible student" in a key high school. She is used to covering up her timidity with thick exercise books. Until an unexpected class reorganization, she bumps into Jiang Yi, a well-known "rebellious boy" in the school. He is a dazzling presence on the basketball court who sweats and is also a "difficult problem student" in the words of the teacher, while she is a good girl who studies hard and even answers questions in a soft voice. They were two parallel lines that had no intersection at first, but they were forced to tie together because of a group cooperation: he helped her get out of her isolation, and she tutored him in the cultural classes that were lagging behind. The backseat of a bicycle in the windy summer night, the side-by-side figures in the corner of the library, cheering each other up before the exam, and their firm protection in the face of rumors, brought two people with very different personalities closer to each other. Under the influence of Jiang Yi, Zhang Qiao slowly shed his disguise and learned to express himself bravely; Jiang Yi also found his inner belonging and direction in Zhang Qiao's tenderness. This is a passionate love about youth, growth and redemption. At the most ignorant age, they met the most passionate each other, broke the prejudice with sincerity, and resisted confusion with companionship, proving that young love is never an obstacle, but the confidence to become a better self.
