The cast of the show was looking into the strengths of Jinyoung on the show which was revealed to be his unlimited positivity. His fellow member Baro asked what he would say if an album didn't do well. To this Jinyoung said, "Our album can be better next time around." As he said this, Heechul joked, "That's because you can rely on your royalties, right?"

Seo Jang Hoon chimed in and mentioned how good Jinyoung is at acting as well, "He's amazing. He's good at acting. He's good at composing music. So how's Bo Gum (Park Bo Gum) doing?" Jinyoung was taken back by the sudden reference to his former acting partner. Seo Jang Hoon continued and stated that Park Bo Gum said he would appear on the show sometime.
