An "awkward" photo of IU and Super Junior's Heechul from his radio show "Kim Heechul's Young Street" has been gaining interest on the internet recently. Having made a guest appearance on the radio show recently, the two took a simple picture for which IU is wearing a baby pink jumper with her hair cutely tied up in an "apple" hairstyle. Heechul's fresh face and his classical "V" pose would make it difficult for anyone to realize a 10 year age difference between the two singers. However, what caught the most attention out of this photo was an unusually awkward vibe from their facial expressions. Both are known to have very bright active personalities, however their smiles are stiff and rigid, as if they felt awkward taking the picture. The administrator who uploaded the photo explained that the two were a bit awkward during their song break, however later exchanged friendly conversations like two good friends when they were on air. Netizens commented, "Hee-nim must get nervous around the current big trend, IU", "Hee-nim has such a young face�. I can't believe they're 10 years apart", "IU is so cute. She looks like a rabbit."
