Fictional Fans

Fic that's about a person dealing with their significant other's friends/family, with the focus on that more than on the ship. I particularly like the variant where their SO is part of an especially close-knit group of friends, found-family or the like, so the poor love interest has to deal with suddenly being dropped among these weirdly codependent and protective-of-each-other people, and then manages to win their way to the inside -- e.g. someone paired with a member of a Stargate team or superhero team or a person who has a canonical best friend who's up in their space all the time.

I can't really come up with recs off the top of my head; I'd have to think about it. Most of the times I can think of that really hit my buttons were back in Stargate fandom, though it's a thing in MCU and some others as well.
