As B1A4 joined the cast of the show and started to introduce themselves, Jinyoung greeted Lee Sang Min happily and said, "You hit the lotto today." Lee Sang Min looked confused and asked why. The B1A4 member bluntly said, "I heard you really wanted to see me," which flustered Lee Sang Min and cooly said, "Uh...I don't know all about that."

Jinyoung explained, "You chose me as one of the three composing idols who you acknowledge." A clip was then played of when Lee Sang Min chose Jinyoung, G-Dragon, and Zico as the three songwriting idols he recognized on the show in a past�episode. Kang Ho Dong then asked, "Did you watch that episode? How did you feel?" Jinyoung said, "Yes I watched it and I felt good."

Lee Sang Min complimented Jinyoung and said, "He's really good at making music and he makes them by himself. He does everything without a team or anything. He produced the most songs when it comes to just exclusive producing (producing alone)."
