In The Key Of Love

A girl and boy meet when they play the same notes on this very special piano. The boy passes away at the beginning of the film so the film is made up of the girl reliving her memories with him every time she plays a note on this piano. At the end of the film, she looses her hearing due to the same accident that killed her lover, so she no longer can hear the notes on the piano which means she no longer can relive her memories with him.
