During the show, they revealed that the two stars first met back when BTS were rookies. Jungkook explained, "We were called to Shinhwa sunbaenim's waiting room when we were rookies, because we introduced ourselves too loudly. The sunbaenims provided advice for us, and told us that our greetings should be more precise. That was when I first saw Minwoo sunbaenim, and I was scared."

Minwoo added, "BTS's introduction was kind of unprofessional. It's important because its the way the team will be known, but after our advice, they did well."
Jungkook then expressed admiration, and said, "Minwoo is a sunbae that I greatly respect. It's difficult to last as a singer, but I realized that it can be an admirable job when I saw Shinhwa sunbaenims."
