This is a pure love story about youth, music and courage. The good girl Lin Xiaoman and the rebellious basketball boy Lu Xingchen met on campus due to an accident, and they went from mutual dislike to mutual redemption. He takes her to see star projections at an abandoned observatory, and she teaches him to play original melodies from leaves. When Father Lu's powerful intervention and Lin Xiaoman's health crisis ensue, they use the rhythm of basketball and the notes of the piano to fight against the world. After two years of separation and watching across the country, until the day of the graduation ceremony, Lin Xiaoman pried open the radio station and let their song resound throughout the campus - "You are the most rebellious item in my youth, the stars and full moon that will never fall."
