The story begins off with a girl in rehabilitation because of anorexia, then she ran away. The background of the story was somewhere in Britain, Essex or Sussex if i'm not wrong. Then the girl went for a swim in a university pool and met a boy who worked as a pool boy there and they became friends.
The girl lived with the boy eventually and the girl sent some her music in tapes/cd's to a local radio for them to hear. The rest are vague memories, all I remember is the boy taught another girl piano or something in her house and the three of them became friends.
It's a musical movie too I think, the movie is not old. I reckon it's from 2010-2015. The quality is quite new.
