I don't know for sure but with everything I've read and seen...yeah I believe so. The occult use very old practices and angel magic, they are allowed to do this because angels allegedly from what I've watched on supernatural and read in books, can be used as somewhat puppets this includes possessing a vessel and making it perform superhuman feats or put on an other worldly performances, sometimes I believe it's obvious like micheal jackson but other times in kpop concerning certain famous groups I believe people would never guess because they seem so normal and they're korean we don't know korea so we take any of their behavior is normal more or less or just a cultural quirk. Korean people won't question them because they are saviors of the economy.
I actually haven't seen any of bts' parents in a photo before except maybe v's, I was just going off this is how these super rich familes work. They will normally pick and choose different races to come into their folds so they can be over another race that the other race couldn't control because they look too different so they just mix in a little and create a ruling class, and bts is way to famous not to be suspected of being apart of that. They have gone beyond any modern famous asian entertainers. It's astronomical. There is no way they are just some normal kids. But I have to say they played the long game. I really believed they were these sorry poor kids, but that is statistically impossible. Even relatives of famous modern asian americans don't have that high level of clout. When I found out yoongi was related to royalty it just seemed very obvious the rest are more likely probably royalty as well, they can't just reveal it because that would be too suspicious. Concerning them looking Caucasian I never really looked at them that closely but a lot of kpop stars don't even look Asian much less Korean. I think the mixed ancestry is more common in the upper class and that's why they are the upper class. Everyone wants to look like them but can't no matter how much surgery they get but they can't figure out what's' different.
