SECRET's Sunhwa, who's known for being slightly "air-headed", might actually be a genius. On the latest episode of "Radio Star", Sunhwa was asked by host Yoon Jong Shin about whether her ditziness was an act. She answered, "During a recording, a math problem was suddenly brought up, and I answered it wrong. Then everyone started laughing. At that moment I thought 'Yes, this is it'. From then on, I would always answer wrong on purpose." After hearing this, the hosts said, "If it's really an act, you're a genius. It's on the status of "Usual Suspects"." Meanwhile, on the same episode, Kim Heechul also labeled Sunhwa as the type he would like to confess a crush to at least once, to which Sunhwa replied, "Please confess at least once." Source: Nate
