There are plenty of youtube documentary videos and google documents, look up for it
those are more reliable and realistic rather than believeing this on the basis of some butterfly and broken glass symbol.
officially its a failed project if u look up for the documentaries. But if its secretly perfected in a way then we don't know. I say like this because those victims basically become physically and mentally stonned and very weak, even in some of those youtube videos which show victims various personas working in various categogies, their physical stamina isn't normal. So in this scenario if we want to categorize those kpop idols who need to sing, dance, workout, practice, tour, do shows and so on, this doesn't fit in where they need to be very strong to handle all these physical labor. They are just drugged up to its core and overworked gotta say and so occasionally show up so called all those glitches and spaced out behaviours.
