Kousei hasn’t played the piano in two years. A musical prodigy from a young age after being put through hell by his late mother, he finds himself unable to play following her death. His childhood friend, Tsubaki, tries to coax him back into the world of classical music, saying that his part-time job as a karaoke transcriber is a sign that he still loves music. He stubbornly refuses, declaring that he was turning his back on his piano-playing days. That is, of course, until Kaori Miyazono enters his life and changes everything.
