Jung Hyung Don questions whether Oh Hyuk really lives alone or not while visiting the singer's house

On December 21, MCs Jung Hyung Don, Defconn, and Yoo Se Yoon visited the home of singer Oh Hyuk for the first time on tvN's 'Livin' the Double Life'. 

Defconn commented, "Oh Hyuk didn't really open up about himself. I'm actually curious what he has inside his refrigerator."

Upon entering the singer's home, Jung Hyung Don said, "The very first thing I do as soon as I enter a person's house is, I use the bathroom." Afterward, Jung Hyung Don sat down on the couch and said with a serious expression, "I'm not sure if I should be saying this right from the start..."

Jung Hyung Don then asked Oh Hyuk, "Are you sure you're living alone? There's more than one toothbrush." Yoon Se Yoon also discovered two wines glasses in the cupboard, and questioned, "Why are there two wine glasses?"

Oh Hyuk looked rather uncomfortable and answered quietly, "I don't know, it came as a set."  Seeing his expression, Jung Hyung Don added, "That's right you need two because you're single."
