Before the Rain Stops, Please Hear Me Out

Five years ago, Sakuma Ritsu suddenly lost hearing in his left ear, and the cause could not be found. From that day on, he could see the "remaining sound" lingering on the rainy day, but chose to pretend not to see it. Until that afternoon of heavy rain, a girl wearing a yellow raincoat who had lost her name and memory stopped him: "You can see me, right?" She only remembered an out-of-tune melody and a sentence stuck in her throat that had to be said no matter what. In order to help her retrieve her last words, Ritsu took her hand across the railroad tracks and walked into the forgotten old music classroom. But when the fragments of memory were pieced together, Lu was shocked to discover—— The person standing outside the music classroom door five years ago was himself. "No response and no hearing are always two different things." Before the rain stops, can you still hear those words that were five years late?
