For Jin Totsuki, playing the piano was his sole reason for living. Despising his right pinky finger, which was left paralyzed from his father's abuse, he spent his days playing piano at a nighttime establishment where high schoolers shouldn't even be working.
Amidst this, a woman appears before Jin—Kofuyu Harumi, his father's ex-girlfriend. When this lonely boy plays the piano "for someone else" for the very first time, the entire world is shaken by his raw genius.
A drama of rebirth and glory forged by two scarred souls, opening the path to their future!
