Okay, let's see. Chapter one: Remus friends find out what he is. I own nothing.
Remus was lying in bed, munching on some chocolate. Just then, the door opened and James, Sirius, and Peter walked in. They all looked unusually serious.
"Hey, guys," he had said.
"Hi," James said after a pause. And then, "Listen, Remus, we're tired of you lying to us. We've all agreed. No one is leaving this room until we get some answers."
"What?" Remus had asked, the perfect picture of confusion and innocence, though his mind was working frantically. "I haven't been lying to you guys."
"Yes, you have," Sirius answered before James could open his mouth. "You just did. And we're sick of it. We're your friends, Remus, and you can tell us anything. At least tell us where you go each month."
Remus calm facade shattered. "Fine," he whispered. So this was it. After a year and a half of (almost) perfect bliss, he was going to lose the only friends he had ever had. "I go up to the Shrieking Shack each month."
Peter had gasped, of course. "Why would you go there? It's the most severely haunted building in Britain! Have you ever heard those noises?"
Remus wanted to say, yes, I've heard those noises. Those noises ring in my ears. I practically hear nothing but those noises, Peter. Instead, he said, "Ghosts don't make those noises. I do."
James and Sirius's expressions turned gleeful. "Awesome! Can we come too, some time?"
"No!" All of them were surprised by the strength of the word, even Remus himself.
"Well," James said, a little impatient, even more concerned. "Why not?"
"Because," Remus said. "It's dangerous." I'm dangerous.
"But if we come it'll be less dangerous, right?" Sirius said. "We can share the burden of whatever it is."
"NO!" That thought was too much. He would not let them share his problem. His... lycanthropy. "You can't come! I won't let you!"
"Why not!? Obviously, whatever is up there is dangerous and you're facing it all alone! You need our help!"
Remus was on his feet now, yelling at a stunned Sirius. A shocked james. A quiverring mass of Peter. "Yes, what's up there is dangerous, but I can't let you get near it! It would kill you! Or, if you didn't die, you would live a cursed life! A life like mine!"
"W-what do you mean?" James asked quietly, his eyes wide and shocked. Remus was never angry. Remus was always calm. Remus never cried. But he was now, tears coursing down his cheeks. But he kept talking, a strange, wild look in his eyes.
"A life like mine, Potter. A cursed life. Do you know what that means? It means that my parents had to go into hiding with me when I was three years old. It means that have never had friends. It means that I shouldn't even be here. It means that if you come up to the Shrieking Shack with me, I will kill you. I won't mean too, but I will. I won't know what I'm doing, so I will. I won't recognize you, so I will bite you. And, if you somehow survive, you will be just like me. A beast. A monster. A horrible creature that has to be locked away each month.
"A werewolf."
They had all stare at him, their scared, concerned faces morphing quickly into cold hatred. For him. They hated him. He should never have come to Hogwarts. He knew this would happen. He should never had made friends. He knew this would happen. He knew. He had always known. But he had done it anyways, and it had been the best time of his life.
