At this current moment, it seems better for her to stay with T-ara doing activities together, and probably having a downtime together as well. The amount of physical stress for their beyond crazy schedule (Japan and Asia tours) is already very high, TV appearance would probably add more physical and mental stress from what's leftover from the scandal.
But, my heart is still pounding over this kinda news for Eunjung. We know how much she is into acting. She was originally trained as an actress, then sidetracked becoming an idol. Still she was doing great as an idol actress. And in Star Life Theater she said how much she wanted to established herself as an actor, despite feeling very happy to be with T-ara.
Hope you'll get whatever is best for you, Eunjung. Be it with busy with T-ara or acting, be happy!
We'll always support you!
Sidenote: KKS should slow down for real. It seems the scandal only fueled his ambition to squeeze T-ara even more.
