When asked, "Do you plan on going to see him in the army?" Hyungsik said, "Right before he went in for training, Kwanghee called me 3 times, but because I was filming, I wasn't able to answer. When I saw later, I called him right away, but by then it was too late. But isn't 3 calls too obsessive? Anyway, I feel like if I go see him, I might get my hairs torn out of my head."
