i've seen ppl theorise that gyuvin had a nose job (or maybe some other work, could be forgetting) bc of a scar tho i haven't spotted it (also there's this one predebut pic of him on a soccer field and he looks way different like i just don't believe he's natural at all) and gunwook probably had his eyelids done judging by pics, maybe nose? idk? with yujin it's hard to tell bc it's probably down to puberty and i hope that's the case he's too damn youngggggggg but also when has the kpop industry ever been about morals, he's likely had something done it's just that i can't tell
