Hello! I'm looking for a story, I can't remember the name or author but I remember the main character was a male OC who was some kind of vampire royalty. He came to Hogwarts and fell in love with Draco and mated/bonded with him. He also had another mate who was also a male OC and mated with Harry later in the story. I also remember that the vampires in the story used high elves as slaves/servants instead of house elves. I'd appreciate any help you can give! Gomapseumnida!
