Koyote's Shinji shared advice for junior co-ed group KARD.

On the May 14 airing of MBC Every1's 'Video Star,' B.M and J.seph, the male members of KARD, made a surprise appearance to show support for Koyote. 

The two members performed "Disco King" with Shinji, and shared, "Koyote is a legendary co-ed group. We adjusted our schedule for this collaboration performance (with Shinji)."

Shinji, who has been promoting as a member of Koyote for over 20 years, shared advice for her hoobaes, stating, "I think you have to fight whenever there is an issue. I think you last long if you fight and makeup often. Things get out of hand if you just let it build up. And also, no dating within the group and always be precise with money."
