Niall, Nandos and Nightmares- One Direction Fanfic

Niall keeps having nightmares about the girl he left behind. The girl he was in love with. He can't help but let the guilt flood over him when he realizes that he left her there with her abusive father, long scars decorating her arms. He still loves her and she never leaves his mind, but he hasn't got any clue on how to find her. That's until he meets her once again, fleeing from her home in the streets of London.
