Since you were born, all your memories were at the Wool's orphanage. Life was nearly a living hell there, the rest of kids would always call you weird, you were alone. And that one kid... Tom Riddle, he was quiet and reserved, but every time you accidentally got in his way, he made your life impossible.
At 11, an old man named Dumbledore came into the orphanage, he said he wanted to take you to a school, which you happily accepted. For once you thought your life was gonna get better, that was before you found out Tom was there too, and he was your roommate.
You both set rules and boundaries and managed to live 7 years having to barely face each other despite one to another argument. Your always minded your own business, you kept noticing dark magic books and objects laying around, but you choose to ignore it.
One rainy night, at 3am you were at the dorm, sipping on your tea and reading a book you had bought at Hogsmeade. Tom had left few minutes after curfew and didn't came back yet, you choose to ignore it, it wasn't your problem neither you cared, he always dissappeared like that.
You didn't cared, until he suddenly stormed into the dorm, probably thinking you were asleep. He was soaking wet and had some slightly fresh blood in his face and body. What the hell was he doing when he was not around?
