On January 24, Wooyoung, Jo Kwon, GOT7's Jackson, and INFINITE's Sunggyu guested on MBC's 'Radio Star'.

The MCs asked Wooyoung about his drunk habits and Wooyoung revealed, "I don't think I have drunk habits... I just get really excited. I keep on climbing things. [I think] because I feel like I need to show something."

Hearing this, Jo Kwon commented, "[When we were younger] Jinyoung hyung (J.Y. Park) insisted that we go to clubs. So the two of us went when we turned 20 years old. I danced crazily but Wooyoung did not know how to party. Bu that changed completely when he entered his mid-20s. He got into it (clubbing) at an older age. Now, I can tell that he has fun."
