On November 22, G.O made a guest appearance on KBS 2TV's 'Yoo Hee Yeol's Sketchbook' and talked about his days in school.

Yoo Hee Yeol asked, "Were you popular when you were a student?"

G.O responded honestly, "I was.  They acknowledged me in Changwon.  At that time, I said I should sell tickets so I united with my friends to create CMU, Changwon Musician Union, and sang.  We once had a performance with 700 seats that sold out."

Yoo Hee Yeol then asked if there was a fan club so G.O said, "No fan club but there was a fan cafe. There were even girls who came to confess their feelings."

G.O was revealed to have had dated twenty times.  He said, "I did not properly date until junior high school.  I am talking about those kinds of dating.  There were not many cases in which I sincerely loved . . . I think those experiences helped me while I sang."
