On the March 2nd episode of MBC’s ‘Quiz to Change the World’, Jo Kwon and Hyorin appeared as guests and shared an interesting story regarding their pre-debut.

During the episode, there was an awkward atmosphere about the two idols and MC Lee Hwi Jae said, “You guys look awkward. Did something happen? You didn’t even greet each other like a broken up couple.”

At this, fellow 2AM member Changmin explained, “Jo Kwon once punished Hyorin when she was a trainee.”

Jo Kwon then clarified, “Hyorin was one of the top trainees of JYP Entertainment in the past. We just intentionally did it so that she won’t get any arrogant.”
