May I suggest Peter Pettigrew x Charity Burbage? I think that would be fun. I headcannon Peter as being really insecure hit desperately wanting someone to love him, then Charity, an attractive, kind, confident girl just kind of. Shows up? She pinches his cheeks and kisses his nose a lot. He melts every time. His friends tease him about it, but they’re all way worse about their significant others.
I think that in a good AU, Peter would become a healer, probably one that specializes in treatment of kiddos (wizard family doctor/paediatrician). We know that Charity is a professor at Hogwarts. I think they didn’t really know each other when they were students. They knew of each other, I think, but only had a couple of conversations in shared classes. Peter always thought she was pretty, but never did anything about it.
Later in life, they met and got closer through Remus when he became a professor, too, at some point in their mid-early 20s. They took it very slowly, starting as acquaintances, then friends, then, after at least a few years, started dating. Now, despite getting together so slowly, I think that they were close enough by the time they finally made it official that they were a bit quicker than usual when it came to becoming serious. The second they got together, they were exclusive. Maybe eight months later they move in together. I’m imagining they’re nearing 30 at this point.
When they get engaged, it’s Charity who gets down on one knee. They get married, like, a year after moving in together. Not a lot of people are invited, but it’s a pretty big event. They both like big parties and events, but they also have a strong sense of family and would want to keep their close friends/family there without people they don’t know well.
Anyways that’s my rant for tonight thank you so much for reading. Please accept my contributions.
