On the December 7th broadcast of Mnet's 'Superstar K4 Top 12 Talk Concert', 'Superstar K4' winner Roy Kim was a guest on show along with finalists DickPunks, Jung Joon Young, Hong Dae Kwang, Kim Jung Hwan, Yoo Seung Woo, Honey G, Yeon Gyu Sung, Ahn Ye Seul, Gye Bum Joo, Volume, and Lee Ji Hye. The guests gathered together and shared some behind-the-scenes stories of their time on the show.

DickPunks' Kim Tae Hyun opened up about Roy Kim's interesting habit and revealed, "After we worked out together and hit the showers, Roy Kim would start stripping off his clothes and dance." Member Kim Hyun Woo also shared, "There are a lot of people who saw Roy Kim dance, but among us the dance became notorious."

Roy Kim responded, "After I workout and enter the shower, it is only natural for me to take off my clothes, that's all there is to it. Why do you talk about me dancing?", hilariously pleading with DickPunks to keep quiet.
