"Japanese T-ara staff tweet: I was a translator/assistant during T-ara's magazine shoot. Back then (around February), Hwayoung definitely did not talk to anyone. She was always calm. She didn't talk to the makeup artists or the other members. She only focused on her work. She always smiled at the staff. She left a good impression." twitter(dot)com / kittychocola / status / 229791579714490368
