hmmm my mind went super blank with fic tropes fuck uuuuuuuh. COFFEE SHOP! be it au or plot related asdfsdfdagd
F: Hate it. Will immediately make me nope out of a fic.
Not trying to trash the slice of life genre or anything, but it's one of my least favorites. Most (actually, all) of my fandoms tend to be sci-fi/high fantasy worlds where the setting itself interests me just as much as the characters, so a fic centered around stripping out all the cool magical stuff that brought me into it in the first place is a hard sell.
For a similar reason, I've never been a big fan of AUs that stray too far from the source material/universe in general. More of an alternate timeline person than an alternate universe person.
