Lin Sui's MP3 contained a recording of Zhou Ye's fight, but on the night he played "Croatian Rhapsody", he heard the sound of blood dripping from the young man's fingertips. The heartbeat under the awning of the convenience store, the impromptu ensemble in the abandoned piano room, the secret formula in the iron box of chilblain ointment - all the throbs were in the summer of his senior year in high school, when he decided to give up his eligibility for admission, and shattered into keys that could no longer be put together.
Concept: ### **Concept** In the gap between reality, youthful ideals and love are like expired rice balls in convenience stores. Even if they expire briefly, they have warmed two lonely souls on a rainy night.
