On this week's airing of 'Masking King,' yet another idol member impressed the viewers and the judges with his surprisingly mature and stable vocals.

Though his performances were moving, Bungeoppang Dad Bought For You lost the final round and was forced to reveal himself as MBLAQ's G.O, receiving a round of applause from the judges. Throughout the episode, G.O racked up compliments on his vocals and matured technique that you won't find in many idols.

During the interview following his last performance, G.O revealed that he feels as though he regained the confidence that he needed as a singer through his appearance on the show. He said, "When Kim Gu Ra and everyone was shouting 'G.O fighting,' I almost cried, but then I held back. There are so many people who are genuinely rooting for me and yet why did I think that I was all alone?"

G.O continued, "When you work together (as a group), you develop this family-like love. But that has been somewhat broken. I would ask questions like, 'What am I singing for?' and went through an identity crisis. Right now, I think that I found my confidence through 'Masked King.' I will work hard to have an active music career."
