If I'm Louder {Larry Stylinson AU}

It's cliche, really. Harry Styles, the music nerd. All the girls find him cute, but they never go for him because he's...well...unpopular. He doesnt mind it, though. He likes being an outcast. Louis Tomlinson, the popular guy. Has all the best friends he could ask for. Almost all of the girls in school want him. He loves the attention, but its not exactly the attention he wants. Everyone has that one best friend that you're inseparable from...in Harry's case, it's Louis. Or, well, it was Louis. The two boys could never be seen without each other, until one summer when something happened with Liam and Louis. Harry has no idea what it is, and Liam refuses to tell him. All he knows, is that it's caused Louis to act like a jerk, and he really wants his best mate back...
