Or maybe they hiding something like drug traffick or other thing ..
Drug trafficking, isnt really a hiding thing when it comes to them, alot of people knows that sum of them are involved in it, along prostitution rings, alot of their friends and connections are pedophiles, rapists, pimps, junkies.
Some people have leaked audios of them talking about such things.
I think that
@Berrywon88 's opinion about the military is valid, they could be hiding many things but more so physical ones, (bru theyre so carefull, but their own staffs leak crap for some cash, or just becuz they hate their guts).
Not to mention, all of them are involved in heavy occultism, some more then others tho, some r real ass junkies, and alcoholics.
Beside ya'll didnt notice that they're really not like other artists, its really obvious that they were put there to fulfill a given rôle, i know some celebrities wanted at first to be like famous and loved art, music thats why they got involved, but in bts's case most of the members give a flying fuck about music, they're like human machines trained to smile, play a persona that was given by the elites, not even hyve can middle in it, sway their ass, lie, and promote certain agendas, some were born into it, and most of them's backgrounds is 90% fake.
Alot of what they call "memories" are scripted, to fit the scenario and the persona that was given to each one of them, btw alot of celebrities do it too, but koreans too the biggest cake.
Even the switch in personas is scripted and planned, Jeon's rebelion for example, he was the perfect fit to such rôle, and people eat that up, ya'll think if the elites didnt allow it, he would do it, ooh hell naah, they have serious crap on his ass that can ruin him for good, he was mean to be the asian version of bieber from the very beggining. So yeah sorry for the long ass post.
