believe it or not I've never thought about this question before!
scoups - jeonghan
jeonghan - dokyeom
joshua - being a capricorn idk (jun?)
hoshi - wonwoo?
jun - im completely normal 8junist in the year 2023 why do you ask
wonwoo - okay I'm realizing I like so many wonwoo dynamics as they are "irl" but I guess dino or jun would be top Ships in a fic sense. But also I did witness the meanie renaissance of late 2020 and I would be lying if I said there wasn't great fic that came out of it
woozi - hoshi soundcloud boyfie is sooo superior I think they're so cute together
dokyeom - minghao
mingyu - oh man.... this is like the opposite of how I see wonwoo in that I rarely have strong thoughts about their actual content but every fic pairing for mingyu is so unhinged and compelling bc people love to kick this man around... maybe dokyeom though cuz I do like a too-close-for-comfort pseudorivalry thing

minghao - take a guess
seungkwan - I can deny many self-professed soulmateisms but not verkwan
vernon - minghao!!!
dino - wonwoo
