The boy thought that closing his eyes meant it was dark, just like being blinded by a ghost in a game, but now he keeps counting silently, and only the sound makes him no longer feel bored. His encounter with music changed his life. This opportunity took him out of the window in his heart and experienced the world outside the window. Through the improvisation of real subjects and actors, handheld photography, actors and space interact with each other, stimulating more wonderful and accidental moments. The heroine of "The Beginning of the Year", Zhang Rongrong, also has a fresh and bright performance in this film.
