Your Lie in April (Japanese: 四月は君の嘘, Hepburn: Shigatsu wa Kimi no Uso) is a 2016 Japanese youth music romance film directed by Takehiko Shinjō, written by Yukari Tatsui [ja], starring Suzu Hirose and Kento Yamazaki and based on the manga series of the same name written and illustrated by Naoshi Arakawa.

[2] Kōsei Arima is a piano prodigy who has won many awards due to his precision, timing, and ability to switch between tempos easily, earning him the moniker "the human metronome".

When, as a seven-year-old, she slapped him after a victory that she deemed unwarranted, he declared his refusal to play the piano ever again and wished that she died.

Indeed, Saki died the following day; this caused Kōsei to experience a mental breakdown during a recital, making him unable to hear sounds from the piano.

She plays the violin in an unorthodox manner, refusing to follow the cues and instead creating her own flow that nevertheless impresses the audience.

Hearing that he wishes to play music with her again, Kaori decides to undergo a risky surgery scheduled on the day of Kōsei's contest.

He learns that Kaori had been admiring him since they were young children and had decided to study violin so she could someday play music with him.
