Yoon Hyung Bin has publicly apologized to 4minute's HyunA through the popular variety show A Man's Qualification. Because of his gag character as Wang Biho, he had to verbally pour out joke-like attacks onto celebrities. These verbal attacks were all scripted of course. Yoon Hyung Bin expressed, "I'm honestly not like that in real life. I have no choice because it's all done for the sake of producing laughter." He continued, "Amongst the celebrities whom I jokingly attacked, there's a celebrity who teared." The tear's owner is HyunA. He revealed, "The verbal attack was 'you withdrew once, can you withdraw one more time.' After the recording, HyunA really started to cry. I felt really sorry." This segment was taken out from Gag Concert and was not shown. In this case, it's understandable to see this situation from the perspective of Yoon Hyung Bin and HyunA. Wang Biho is just a gag man who was following the script, but it's reasonable for HyunA to get slightly offended by the attacks. And it looks like it has ended pretty well.
