Shigatsu wa Kimi no Uso follows Kousei Arima, a former child piano prodigy known as the Human Metronome for his flawless timing and disciplined performances. Raised under the pressure of a strict mother and relentless training, he spends his youth winning competition after competition until his mother's sudden death leaves him unable to hear the sound of a piano. The trauma drives him away from the stage, and he retreats into the quiet life of a junior high school student, spending time with his friends Tsubaki Sawabe and Ryouta Watari while trying to live with grief and the silence that now surrounds music.
His monochrome routine begins to change when he meets Kaori Miyazono, an eccentric violinist with a forceful presence and an uncompromising way of seeing the world. She pulls Kousei back into music as her accompanist, and through a little lie the two grow closer as she tries to bring color back into his life. As Kousei confronts music, loss, and the future he has been avoiding, the series becomes a story about performance, healing, and the fragile bonds that can restore a person's will to play.
