I know most KPOP idols probably know what they are doing and do it for money, but I don't think this stops them from feeling uncomfortable. (It's also weird to be paid to act gay and crap with your members, but that's a whole other thread honestly.) Anyway, imagine being shipped with someone you consider to be your sister/brother and having people refer to you as a couple, writing 18+ fanfics about you doing disgusting things with each other, and creating weirdass fanart. It's become so normalized in KPOP that it's just awful. And if it turns out to be true, the kpop industry literally reject the idol and just shun them out. Fans like imagining them dating each other, but when it turns out to be true, they freak out. I just don't understand how tf they think.
It's not only in Kpop too, it happens to literally everyone. Streamers, actors, anyone.
Harmless FRIENDSHIP shippers are fine though
