Zhou Xuan, the school bully who grew up in an orphanage, had a bass in his piano case that was not worth 3,000. Zhou Xuan only had Fang Kangxue and the bass in his life before. Wen Juefei, the top grader in a scholarly family, has electric guitar tabs and melodies that no one dares to hear hidden in the middle of his textbook. On the day they met on the rooftop, he heard that her strings were not accurate and he took the initiative to help her tune them. A man who spoke with his fists met a man who resisted the world with silence - the fire on the rooftop started burning. A 17-year-old girl and a 16-year-old boy, the secret love in youth likes one hidden in the heart of fire and the other hidden in the thin snow in May.
Concept: Two children abandoned by the world picked each other up on the rooftop.
