Entertainment companies did it to 2pm and they’re going to do it to Exo. Nichkhun and Jokwon were forced to unfollow Jaebum when he left the group. SM Entertainment isn’t going to stop at nothing if they feel like their getting the lower end of the stick. Just word of Kris leaving is doing so much damage to the entertainment group, they’re going to try and break Kris. But all in all, I am 99% sure that the members didn’t unfollow Kris on their own free will, the managers or the reps told them to.
