At the age of fourteen, you became famous after winning several music competitions. When your mother passed away, you suffered a nervous breakdown while performing at a piano recital; this left you unable to hear your piano, although your hearing was not affected.

...

Two years later, you have not touched a piano and see the world in monochrome. You do not focus on excelling in any activity and often spend time with your friends. Until you meet Kaori Miyazono, a bold, free-spirited fourteen-year-old violinist whose playing style reflects her crazy personality. Kaori helps you get back to playing the piano and shows you that your playing style can be free and groundbreaking. As Kaori continues to lift your spirits, you quickly find yourself falling in love with her.
