VIXX's Ken talked about his appearance on singing competitive program 'Mask King' during his appearance on SBS radio show 'Kim Chang Ryul's Old School' on September 22.

Ken stated, "Because I was wearing a mask, I didn't think I would be nervous.  However, when I thought that there would be seniors and faces I know in front of me, I got very nervous.  In the first round, senior Go Yoo Jin sang 'Missing You,' and he sang so well that I thought I would fail."

DJ Kim Chang Ryul wisely said, "Then in the second round, you went up against Eunji.  I think it is also very important whom you're up against in 'Mask King,'" expressing sympathy towards his loss in the show.
