Same actually. Some of them are of course rich af, but even many in rather popular groups still haven't their trainee debt payed off or are still struggling just to everyday life too. Like B.A.P and Block B were big surprises for me cause they have always been pretty popular within i-fans especially, but to find out that they companies paid them next to nth and I think Block B had to even pay for stuff on their own or their parents had to.
Another one for me was seeing in how poor conditions some idols live. Like I remember seeing After School's dorm and how it lacked even some basic furniture despite it being their dorm years and years (i think it was showed in Roommate that Nana was part of I'm not sure) And F.Cuz was showing off their dorm at the time and they had all beds in same tiny room and most weirdest thing was that they had only 4 beds when the group had 5 members

. Its just that you see these idols on stage, all dressed up, hair done, make up done, design clothes, worshipped by fans- and then they go back to dorms to sleep and they have these tiniest messy apartments that are worse than any place you have ever lived yourself.
