My Brother's Best Friend (A Niall Horan Fan Fiction)

My name is Skylar Styles. Yes, Harry Styles is my brother. He was coming home from tour for the summer and he is bringing his best friend. That's right the one and the only, Niall Horan. Yay! Not! I have known Niall all my life. Yet still he gets more aggravating by the minute. But this summer, he is different. Nice, polite and sweet. Oh Lord help me cause I might be falling for my brothers best friend.
