So, this ad is for Nicoleta's bf/soulmate. I think that he would be part of one of the other royal vamp families but maybe he was a second or third son? So he wasn't in the running to really rule anything. In my mind, he wasn't looking to be in any place of power anyway. So instead of taking part in all of the royalty related training, he trained to be a warrior. I think he would be older than Nikki, how much older is up to you since Vamps age differently. But since her family was killed, he has come to Hogwarts with her as a bodyguard parading as a student.

They would have to act like they were just loose acquaintances or maybe even friends but she wouldn't want to let on that they were actually together, so their relationship would be secret around the school. I see him acting like someone who is completely harmless so no one would suspect him, maybe he is goofy and light hearted, maybe a party boy? I don't know, I'll leave this up to whoever takes him! But it can lead to all kinds of fun since Nikki does tend to be jealous even if she knows she has no need to be. Buuuuut I can see them sneaking around to have time together as well. Even if in the halls of Hogwarts she puts him firmly in the friendzone. This is just a loose idea and I'm open for further interpretation or plotting, just shoot me a DM on Discord (kacie#5138) The face I've used here is Marlon Teixeira because they have a few gifs and things together.
