I agree that the public is being biased and only choose to believe what they want. I personally feel that the sudden termination of Hwayoung's contract without any conditions has some kind of dark reason behind this. If Hwayoung really brought burden or showed what they called the 'superstar attitude', why do they terminate her contract without and conditions? This could also be passed off due to her young age.
BUT, if Hwayoung was really bullied, how could she manage to stay herself inside T-ARA for such a relatively long time? The bullying may not have went on for long, and I don't believe she has been bullied.
And I think the most likely cause and reason for all this is an internal conflict or differences between CCM and Hwayoung, that they decided to terminate her contract without any conditions. I doubt there is anything further. And I truly hope so.
