Singer Yonce appeared as a guest and revealed, "I auditioned during college, and I debuted with a group. We were 3 members," adding that she was the group's leader. JR responded, "To be honest, I'm also the leader of NU'EST. Honestly, I think the weight of being a leader is heavy. Wasn't it tiring? I think you'd feel a lot of responsibility."

Yonce said, "I recruited a friend I knew. I felt bad when we disbanded. We debuted in 2011 and promoted until 2012. We were popular with young kids."

JR is currently part of the judge panel on 'Suspicious Singer'.
