4minute's HyunA and Secret's Sunhwa competed for the "Worst at Hangul*" title on the upcoming episode of Bouquet. October 9th is Hangul Day, so to celebrate, the girl idols took part in a competition called "Worst at Hangul Competition." Various girl groups competed but HyunA and Sunhwa rose to the top.  This is no surprise because Sunhwa is known to be a little ditzy. The MC Oh Sang Jin was shocked to hear the girl group members' odd answers to the quiz. This episode will air on October 10th. Source+Photo: Newsen *Hangul=Korean language
