Perhaps Maybe I Dunno (Zarry AU)

Harry Styles is bold and unapologetic. He gets what he wants whenever he wants it, so when he meets a mysterious boy at his grandmum's house, he can't help but rise to the challenge.

Zayn Malik is a hard-working and serious boy who's more concerned about his future and his family than parties and nightclubs. So when he meets his neighbor's newly-arrived grandson, a reckless and irresponsible boy named Harry, his first urge is to get away from his as fast as he can.

Perhaps they can find a way to live next to each other. Maybe they can even be friends. Or, I dunno, will they become something more?
