[All] Mark who gave a hip-hop performance on the Summer stage of Gayo Daejeon

Mark on stage at SBS Gayo Daejeon Summer!
On this stage, I showed off 1999 in a Hip Hop Challenge version with real ballerinas!
I was disappointed that I only saw short versions of the challenge videos and encore videos.
It's fun to see them do this on the Summer stage of the Gayo Daejeon.
