If you're still looking, I have Steve here for Eddie. (Or alternatively Eddie for Steve, but he's new to me!)

I also have a Geralt for Jaskier, though I haven't seen the new season yet!

I'm also flexible on prose or brackets, and prefer some plot to go with smut. Fake dating, idiots to lovers, soulmates, mutual pining are all my jam. Given the canon for both of these are musically inclined, I'd be down with a rockstar au too, or maybe like, Steve/Eddie meeting again when Eddie's made it or a modern au with rock star jaskier. I'd prefer to keep some supernatural in a modern au though!
