A good friend of mine from college (he studied abroad in the US and then served in the South Korean military after returning home) told me that, during his service, he was completely isolated from all of his fellow soldiers because he was one rank above them (because he was a college graduate), which meant that they had to be extremely formal with him, which made socializing impossible. (He was still a nobody in terms of rank, but still a step higher than his peers.)
I imagine that BTS will have a similar experience by design.
