@AIroH iam a huge fan of them, their songs are just so so good, and honestly i haven't been able to attend their fanmeets or concerts yet (not from skorea and broke hashahah) but i think it just works on how they normally works, real person behind those animated avatars, but the difference is just that I think they can somehow interact like hear their fans cheering for them, talk to them, and can hear them sing live, just how a concert is. So yeah we can't see the real them as they work just like vtubers, real person behind an animated avatar, so not really that ai. I am also a fan of 3rd gen and plave made me listen to kpop again :) hope you can try to listen and watch their chaotic mostly streams hahsha they're very funny and very talented boys, hope you enjoy (and possibly join us plli's) :)
