Jo Kwon shared a behind-the-scenes story from their comeback: "After 'This Song' and 'A Friend's Confession', it's been about 5 years since we recorded with [J.Y. Park]... Jin Young hyung grades us when we record these days because he has been so consumed with his audition program ['K-Pop Star']." When asked who received the highest score, they revealed it was Jo Kwon with 50,000 points. Changmin revealed the highest he ever got was 98 points.

When asked which member changed the most since debut, Jo Kwon chose Jinwoon, explaining, "When we debuted, Jinwoon was a student who would wear a school uniform. He debuted in his sophomore year of high school, and somehow became 24 years old. Even before he turned 20, I didn't know he loved drinking so much."

Jo Kwon also revealed the reason for his hiatus from variety shows, sharing, "I am doing a musical these days, and I want to show a more sincere side of me so I intentionally stayed away from variety shows. And after shaking my hips so much, my hip joint is really not in good condition... I don't know about variety-show skills, but I can still win with my girl group dance and kkab."

They then played a game in which they share their concerns and get a random answer from a book of wise quotes. Jo Kwon shared his concern, "Will I be able to get a girlfriend?", and the answer he landed on in the book was: "Even if you have a lot to choose from, it's as difficult as having only a few," making the members joke that Jo Kwon must have a lot of popularity around girls.

Changmin also asked if his 30s will be better than his 20s, to which the book replied, "Focus on your household duties." Jinwoon also asked, "Will this album do as well as 'Can't Let You Go Even If I Die'?", to which the book replied, "Don't worry."
