The 4minute girls returned on the Music Bank stage on June 4th to perform their latest hit song, Huh. What caught the attention of fans however was that Gayoon was donning sunglasses, which was a first since they begun performing this song. If you recall, only Jiyoon wore sunglasses during their previous performances, so it was a surprise for fans. But if you recall again, Gayoon was sporting a bandage over her right eye when she voted in local elections two days earlier. It was said that she had injured her right eye and was currently undergoing treatment for it. But with only one good eye and wearing sunglasses on a semi-dark stage, it must be some feat for Gayoon to go through the entire performance without any major mistakes. We wish her a speedy recovery though! http://www.youtube.com/watch?v=fdNJdSew7ko
