"Who would've thought a dark heart could love so much" (Previously know as A Million Years) Vampire!Harry AU Harry has been alive for over a thousand years. He has been thrown around and stomped on by everyone he has ever cared about. It doesn't help that anyone or anything he grows attached to ages and dies unlike him. He is a monster. Louis is a very odd 21 year old. He is very ignorant and naive. He doesn't know the difference between danger and curiosity. But he doesn't care.
