When they live performed “ Twin”, HanGeng was not allowed to perform on the stage because he had a problem with his visa and he couldn’t choose channels to be appear on. He cried and asked his manager that he would use mask to cover his face when he performed on the stage. HeeChul’s not satisfied about that so when they performed he took off HanGeng’s mask. HanGeng tried to avoid from the camera but HeeChul hold him and keep him performing.
