Im a diehard Kamilia.
My bias is Kara, not essentially their music, because there are a few songs i can't stand, like pretty girl, but everything else. Gyuris rapping, Nicole on Heroes, Jiyoung on IY2, Hara on IY. And lets not forget KARA Bakery, I fell in love with them even more because of that show. So, i think KARA is my bias because there personalities.
But anyway, right behind KARA is T-ARA, because i love all T-aras music, and i think they are each hilarious on variety shows. I don't know why KARA is in my heart more than T-ara, probably because they were there first.
