I'm going into this fully expecting not to get any real details, or even anything close to the truth. I am worried however, that others are going in expecting a full detailed account of the true reasons Hwayoung was removed from the group and will just be further incensed when that doesn't happen.
Being a true realist, this seems as if it's a publicity stunt. Now that Korean promotions have ended and they'll be out of the limelight for a little while as they promote over seas, it seems like a pretty convenient time to release a mysterious program that promises to answer questions everyone had pretty much accepted they wouldn't be finding out the answer to. It lights the flames and gets people discussing T-ara for another few weeks.
Now with that said I do hope we get some real insight as to what the situation was and is, but I certainly won't let those hopes get too high and I suggest others follow suit.
