As D.O. looked nervous, Chanyeol started off by saying, "The first impression wasn't very good. D.O. had really bad eyesight that when he looked at people, it appeared as if he was glaring at them." D.O. then explained himself, "My astigmatism is really bad. I can't wear contact lenses because they're so uncomfortable and I couldn't wear glasses at the time so I was looking at people like this (makes an evil looking glaring face)."
