The members of Koyote confessed there was violence within the group. 

The February 8 airing of KBS2's 'Entertainment Weekly' included an interview with the long-running trio. 

Reporter Kim Tae Jin asked if the members ever got in a physical fight. Bbaek Ga revealed, "Jong Min hyung used to get beat by Shinji." Kim Jong Min agreed and said, "It wasn't just one or two times." 

To this, Shinji explained,"To be honest, I did seriously hit him at times," however, "I didn't hit him hard on purpose. I hit him lightly as a joke but that must've felt strong to him."

As for the secret to their long-running teamwork, Shinji coolly said, "Not being too successful?" She explained, "We have never won 'Daesang,' but received everything below that. I think we long-lasted like that without being at the top."
