I have posted this on other forums, but I would like to state my point of view here as well.
It was Core Content Media's CEO Kim Kwang Soo who kicked Hwayoung out. I believe you would know that Kim Kwang Soo is a very powerful and influential man in the Korean entertainment industry. If the bullying did happen, the best way to salvage this outbreak is to make Hwayoung stay and deny the bullying. Kim Kwang Soo definitely has the capability to do that; in fact, he could have easily done that. Hence, I believe the conflict has nothing to do with Hwayoung and the rest of the members of T-ara. The way I see it, the problem lies with Hwayoung and Kim Kwang Soo. Something must have happened between Kim Kwang Soo and Hwayoung, and he's determined to ruin Hwayoung's career, even at the cost of T-ara's.
Either this or he really needs to set up a public relation department and go for critical thinking lessons.
