Paper Aeroplanes - muke au

Luke Hemmings has lived in Sydney with his mother all his life. A lovely old lady lives in a house to his right, the house on his left has been empty as long as he can remember.
Until one day when the moving vans pile up outside. A boy with wild hair, a few tattoos and pierced ears moves into the bedroom directly opposite his.

(Crappy description. Please remember this is an au so not everything is correct, I have changed things to suit my story.)
