The artist went by 'Racing Car' on the February 11 episode and performed against 'Gypsy Woman' in the second round. As soon as the slow, melodic instrumental of Lee Juk's "I Didn't Know That Time" came on, the panel could not hide their surprise by the music choice as the singer showcased his rough and low voice prior to his solo stage.

However, everyone was pleasantly surprised by how 'Racing Car' was able to carry out the song and a panel member even commented that he switched up the singing style a bit. The YG artist received a round of applause but the second round was the end of the road as the 'Gypsy Woman' outlasted 'Racing Car'.

No one expected to see who was behind the mask. It was none other than iKON's Koo Jun Hoe! During the interview, the iKON member expressed how big of a fan he is of the show and mentioned many international fans desired to see him perform on 'Mask King'.

How do you think he did?
