During the show, Kim Chung Ha revealed, "I used to be a backup dancer for B1A4 before debut. It feels cool to meet them like this on a variety show." She continued, "Jinyoung sunbaenim wrote many songs for us during 'Produce 101'. I told him about how I used to be a backup dancer then. He was surprised and said he also told CNU sunbaenim about it as well. I've also met with CNU sunbaenim at a broadcast and he recognized me and talked about my backup dancer days. I felt grateful."
