Second Chance

Second chances don't come really often, if not at all. Does everybody deserve a second chance? Or is it something you earn? Will it make any different in the end? Or just like an old saying, let what happened in the past stay in the past?

Or, an AU where Louis messed up and had to accept the fact he lost his boyfriend. He could not do anything but letting Harry slip out of his life. But he could never let him go, leaving him completely miserable because he has always loved Harry so much and he did not think he will ever stop to do so. Louis is nothing without Harry, and he knew Harry has always felt the same. Now, will Louis get lucky enough to get a second chance to fix his broken heart and get back his love?
