Yeah, as has been stated many times, the problem is trust is lost due to all the blatant lying of the CEO. If he hadn't posted so many obvious lies and incongruent statements, everyone could easily think that most of the T-ara tweets, videos and reports were misinterpreted.
But because the company has been so sneaky, irresponsible and dishonest, I'm inclined to doubt even Hwayoung's post. Since KKS stated yesterday that he met with her parents and presented the public with a fairyland image that the parents are okay with all he's doing, I'm more inclined to think that he used his power to make Hwayoung post that. It'd just take a little talk with the parents about how he could affect the twins' futures, or even a little money. I'm sure it doesn't take a lot to persuade someone in such an unfortunate position (regardless of whether Hwayoung was a victim or not). Like everyone said since the beginning, no matter what's the truth, they can just sweep all this under the rug. That is, unless the public keeps pushing for the truth, I guess.
