Kousei Arima was once a piano prodigy, renowned as the “Human Metronome” for his flawless technique and mechanical precision. Under the strict guidance of his mother, he dominated competitions and earned widespread acclaim. But when she suddenly passes away, the shock leaves him unable to hear the sound of the piano, forcing him to abandon the stage entirely.
Now a junior high school student, Kousei leads an unremarkable life, spending his days with his childhood friends, Tsubaki and Ryouta. Though he has turned away from performing, music remains a distant shadow in his life—until he meets Kaori Miyazono, a spirited and unconventional violinist. With her free-spirited playing and boundless energy, Kaori pulls Kousei back into the world of music, challenging him to see it in a whole new way. Through laughter, heartbreak, and a little white lie, she paints his world in color once more.
