The video started off with a segment where the cast has a chance to find out more about their guests - Irene was up. She said, "I used to take a lot of photos of nature but on a recent family trip, I realized I didn't have many photos of my parents. Now, I take photos and videos much as possible of them whenever I can. I also talk to my parents a lot, I think I spoke with them on the phone much as four times a day when I was a trainee."

After that specific moment, they moved onto the next question of "What did I make trendy while promoting as Red Velvet?" The cast quickly tried to guess the correct answer. Min Kyung Hoon joked, "Electronic cigarette?" to lighten the mood. Then Lee Sang Min guessed "Public bath key?" while looking at Irene's wrist thinking it was a key. Irene responded while lifting her wrist, "This? It's a hair band." Heechul asked her to tie her hair up with it and when she tried to, the members of the show stared in awe and couldn't help but say, "Wow...you're actually so pretty..." to make Irene blush.
