When asked, "Your favorite girl group is?", Ji Hyun Woo answered correctly, "A Pink." To the question, "Your favorite member is?", he knew just what to say, replying, "Eunji." When asked, "What is their recent title track?", the actor showed off his knowledge about A Pink, "Chu", to which A Pink's Eunji asked, "What Chu?", he specified, "Mr. Chu."

Shin Sung Rok, who also became known for being a KakaoTalk emoticon doppelganger, shared, "I also use those emoticons a lot." Lee Se Young hilariously revealed, "I get confused whether it's Sung Rok oppa or the emoticon." When asked what he would like to say to the person who first came up with his KakaoTalk emoticon doppelganger nickname, he said to the camera, "I'm really curious about what you look like. I really want to know what you look like."

When asked, "While filming, is there anything you worry or have concerns about?", Eunji shared, "[Lee Se Young] unni has big eyes so it's burdensome [to me]. When I smile, my eyes slightly disappear. But [Lee Se Young] unni's eyes sparkle even when she smiles." Lee Se Young added that she is jealous of Eunji, "It's like this. When Eunji smiles, the way her eye [shape] bends is so charming." Shin Sung Rok also chose Ji Hyun Woo's eye smile as the feature he's jealous of and Ji Hyun Woo chose Shin Sung Rok's jawline.
