On the July 7th episode of the variety show, Ong Seong Wu and Lee Dae Hwi of Wanna One appeared as special guests. While talking about their connections to the cast members, Ong Seong Wu and Key spoke of their amicable friendship. 

"We met through another variety program," said One Seong Wu. "Even after hanging out just twice, Key 'hyung' really made me feel comfortable, as if we had met 10 times." However, the other cast of the show kept teasing Key by saying that the friendship was too unexpected. "Why didn't you tell us earlier?! Do you even have [Ong Seong Wu's] phone number?" said the cast, as they interrogated Key.

In addition to the two idols' friendship, Lee Dae Hwi and Hanhae talked about being friendly label mates at Brand New Music. "Hanhae 'hyung' is like the bible at our agency. When I was a trainee, the policy was: 'Diction and tone should always be like Hanhae's'." Hanhae, who was always treated as "the fool" on the show, appeared proud as his junior spoke highly of him.
