Harry is co-owner of a bakery and all is going well until a coffee shop opens next door full of new ideas, the co-owner of the coffee shop Louis and he get off on the wrong foot and before long a full on prank war begins, but do they hate each other as much as they make out to?

Louis is an accident-prone Taxi driver who believes his friends are out to get him when a certain curly haired boy is involved. Harry works opposite the taxi’s main office and Louis’ had his eye on him for a while but what happens when they fall into each other’s lives finally?

When Harry Styles goes to his uncle's in Florida for the summer, he's reminded by the company his two dating friends, Liam and Zayn, how hopelessly single he is. The trip he expected to be fun turns slightly sour on his first day there. Until he meets Louis Tomlinson, that is. And even though Louis is more different than Harry could imagine, Harry slowly begins to feel like Louis could very well make his seemingly lonely trip the best vacation of his life.
