Best Friend's Brother- a liam payne fanfic

Kaitlyn is just a normal teenager juggling school, and volleyball, and having to deal with her parents constantly arguing. She has her best friend, Anna beside her to keep her grounded. But what happens when she falls for Anna's bad boy older brother, Liam? Is it the bad boy persona that turns her toward him? Anna isn't stopping the two from connecting, but she did warn Kaitlyn about Liam's "ways". Liam has been known to have gotten around with many girls; never settled for a real girlfriend. Kaitlyn is skeptical about any boy after what her ex did to her. And Liam is lonely, being the reason he's slept with so many girls. Could the two having feelings for each other change all of that?
