I think the samelike i wrote in another post, i think they act normal and their age off camera ..
Their roles are just a part of their jobs I'm convinced that jn and jm and jh act nothing like their btss personas irl
Yn isnt faking much so the sarcastic egotistical a**hole vibes I get from him are authentic and jk isnt faking much either imo and I believe he actually is as nice as he seems..I mean I dont think jkay is a a**hole like yn and rmm and is probably the most genuine member
I think those two(yn and jk)are the ones who show the most of their true personality out of all of them
