iKON's Koo Jun Hoe exposed Song Yun Hyeong on MBC Every1's 'Video Star'.
On October 16, all members of iKON guested on a talk show together for the first time. During the show, the members revealed that Song Yun Hyeong has the habit of undressing in the elevator. To this, Song Yun Hyeong explained, "No, it's because I want to wash up fast after sweating. I want to shower fast as I can so I undo several of my buttons."
Koo Jun Hoe then revealed, "Yun Hyeong hyung is very healthy. He loves girls the most in our group."
