I really liked her, in fact, I loved her rapping in DBD... I would repeat the rapping part over and over. This is hard to say but this has to be true to some extent. Whether they told a mild incident or not we don't know, there may have been worse hence the "protecting Hwayoung". They maybe twisted the story a bit, KKS did mention the accounts got hacked. It is very possible that CCM have the passwords of all the members, so they can terminate the Twitter whener they feel like it's needed. So after all this we don't for sure if it were the girls or not who tweeted, just because of that one statement from him. Some idols don't even have a cellphone for the same reason this won't happen.
But seriously, you really think that the girls would bully her just because? Then you really think pretty less of them.
