B1A4 appeared on the February 27 edition of SBS's radio program 'Cultwo Show' and talked about their dorm life.

DJ Jung Chan Woo brought this up first, "I heard that B1A4 are living in dorms.  Which one of the members has the most toxic smelling feet?"  CNU said, "I don't think any one of us are that severe."

The DJ continued, "Then does one of you not have smelly feet?"  Sandeul said, "I don't know."  Jung Chan Woo replied, "I heard that CNU exposes himself the most, but why does he do that?"

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.
