I'm Oliver You, Tom Riddle

Backstory

Male OC half Veela through his mother's side, just turned 11, and is at Hogwarts School for Witchcraft and Wizardry the same year as Tom Marvolo Riddle. He is sorted into Slytherin despite his protests to be put in Hufflepuff (But it's closer to the kitchens! And it's warmer! I'll freeze to death down there!)

They become friends. Tom takes pity on Male OC because Male OC is always shivering, despite wearing several layers of clothing and sitting as close to the fireplace as he can without actually catching on fire. He suggests sleeping together at night and sitting close together on the sofas/chairs to keep Male OC warm.

Eventually they get into the habit of constantly being close over the first year, sleeping together, napping together (Male OC naps while Tom studies), just being around each other.

Then the year ends and everyone must return home for the summer. Male OC doesn't want to, but barely protests. Tom doesn't want to return to the orphanage either, but wisely states that it'll only be for a few weeks, and then they'll be back. Too also promises that Male OC can still share his bed and seat and whatever else he wants to.

Over the summer, Male OC's single father grabs his sons chin while they're eating dinner one night and turns it so Male OC is looking at him and notices that his son is becoming quite the pretty little thing. He leaves it at that, leaving Male OC wondering what just happened.

September returns, and life is back to normal at Hogwarts.

Male OC found out over the summer of his fourth year why he doesn't have a mother around; his father raped her, she dumped the monster he forced upon her on his doorstep, and left with no regrets. His father told him that soon enough, he'd have to start paying to live there, all this charity work is starting to drain his bank account. When Male OC asks what kind of work at the table, his father grabs his ass, hauls him into his lap and says that they'll just have to "figure something out". Male OC doesn't want to go back for the next summer, but refuses to tell Tom, he's been getting more and more protective, as of late. Male OC decides to simply ride it out until their Seventh year is over, then he and Tom can run away together, no one will ever see them again. He just has to convince his Tom, who has become almost obsessed with the Dark Arts, that it would be the best for the both of them.

Our story picks up at Hogwarts. Things continue as normal, Male OC and Tom becoming more and more attractive as the years go by, which brings us to their Fifth Year.
