KBS recently announced that JYJ can’t appear on their Music Bank.
On the 18th, the program posted a note on their official homepage, “Entertainers, who is in litigation, can effect the result of the lawsuit if they appear on TV. We will watch the development of the events and then we will decide about their appearance.”
Since JYJ is currently in litigation, KBS will not allow JYJ to appear on their programs until the result come out.
