Behind - Larry Stylinson AU

Harry was slower than the other kids. In everything, really. He couldn't learn as fast, his brain wouldn't keep up. Harry knew he was different, no matter how hard he tried to be the same. He was in separate classes and he was stuck behind everyone else. Even at age nineteen, graduated from school, he can't go to college with his best mate Niall. He's stuck in the back, and he hates it. No matter how much Harry tries, he just can't catch up, he can't be accepted fully. But as a new friend Louis realizes, maybe he can make Harry feel accepted without the whole world being on board.
