CCM's level of management isn't exactly what you can call sane at all. In fact, one might say they're probably among the most incompetent entertainment talent agencies in the Kpop industry. Even the Big Three are likely to crack a few jokes about them occasionally.
If you checked their previous record, SG Wannabe, Lee Hyori and SeeYa were all under CCM years before T-ara even debuted - all of them left CCM after just a few years, while SeeYa's Nam Gyuri left, followed by the group's ultimate disbandment last year.
Plus, look what happened to Co-Ed. CCM practically dug their graves and buried them there.
Upon Nam Gyuri's departure, KKS actually made the news more bigger than necessary, going as far as slandering her in public with some of the most despicable and villainous lies. KARA's lawsuit a while back also made KKS even announce that they should be BLACKMAILED and FORBIDDEN from the entertainment industry. As long as that nutcracker is in charge, T-ara and CCM as an organization aren't going to stay happy.
KKS is more concerned with beating SM and dethroning SNSD as Korea's top idol girl group, even if it means he has to change members of T-ara. He doesn't give a sh!t about the well-being of the current members.
