CNU said, "I think I do it because when I'm with members, I feel comfortable like I'm with family. �There are even times when I don't wear underwear. �One day, we finished our schedule and came home where I, in an exhaustive state, stripped off all my clothes and was on standby to take a shower. �However, I was tired so I fell asleep. �I woke up to see a shocked Sandeul."

Sandeul said, "When you go to a sauna, there are naked people sleeping sometimes. I was so surprised. �I thought it was a sauna. �I was shocked so I covered him with a towel," making everyone laugh.
