During their appearance on KBS Cool FM's 'Park Myung Soo's Radio Show' on March 6 KST, Koyote's Bbaek Ga and model Lee Hyun Yi participated in a segment together, delving into the theme of secrets between couples and loved ones.

Bbaek Ga bravely disclosed, "I underwent surgery for a brain tumor, but I chose to keep it a secret from my parents." He further explained, "I didn't inform my parents about my illness. They only found out after reading about it in an article."

Reflecting on that challenging time, Bbaek Ga shared, "It was a significant ordeal for me, especially in my 20s. I struggled to cope with the situation and didn't want to cause my parents further worry."

Upon hearing his story, Park Myung Soo expressed concern, asking, "How are you feeling now?" Bbaek Ga reassured him, "Take a look at me now. I'm in good health. Everything is fine."
