Heartbreaker (Larry Stylinson AU)

Harry Styles is the school player. Every girl wants him - and some guys as well. But Harry leaves nothing but broken hearts, sometimes takes someone to dump them or cheat on them.
Cupid, the god of love, doesn't like how Harry works with love. So he sents one of his Heartbreakers down to eath - Louis, his best one.
Louis always takes his job serious. Soon he makes Harry fall in love with him. But what happens if Louis begins to feel things for the curly haired lad? Things that he isn't supposed to feel? Will he keep following his job? Or give everything up?
