just looking at the way the company is acting right now....freaking out and denying everything, I think yes it will be extremely hard for them to leave
they will probably blackmail them to stay
they said they wanted to start going solo in 2020 (but the company said NO...
they also cried on stage during MAMA 2018 saying they thought about disbanding (remember this?)
and now it happened again
they went on video, cried, saying this was the beggining of a hiatus....and now they are going back again
these guys are obviously forced to stay together
