T-ara FTW 1

I have started becoming in love with T-ara (A K-Pop group) lately! Especially after watching both of their Drama versions of their songs, Day by Day, Sexy Love, and Day and Night. I don't know every single member yet (none actually) but i must say i LOVE the girl with the pink hair! I still don't know her name yet, so if you know it, could you tell me? :3
