The main cast members failed to be present at the show, but they revealed infinite affection for IU, who took the character Jang Man Wol in "Hotel Del Luna." And at the show, Jeong Dong-Hwan said he decided to appear without looking at the news mentioning it was IU's lead film.

Jeong Dong-Hwan said, "I am either caring or not at the scene. But I think I came up with a very warm father feeling." "I don't know what to do on Chuseok or New Year's Day. That's why I often work, so I kept seeing her through the play," he said, adding that he had been communicating with IU steadily. "It's not easy to look at Samuel Beckett's "Waiting for Godot" at a young age," Jeong said. "If IU was the main character, I would like to be a wheat egg."

Later on the show, a surprise phone call with IU happened, and she was asked about her relationship with Jeong Dong Hwan, IU said, "He is my father in the 4th episode of 'You Are the Best!'" and added, "But when I appeared in the 4th episode, I was so sincere. If there was a tearful act until the end of the drama, I would post a photo of my teacher and act as a tearful actress," she said. "After that, my teacher gave me a lot of advice and invited me to the performance, so I continued flying the kite," which warmed the mood.

As for Mina, who chose IU as a role model, Jeong said, "Isn't she from the survival program? It was my original work then. I also talked to Mina at the dinner table. She really worked so hard on the show and her friends worked hard, too, but her visible passion looked so good than others that I wished that she would do well," he said.

The "Hotel Del Luna" casts showed off their loyalty by taking care of IU who couldn't join the team on the show. The guests on the show who all had special ties to IU, revealed various anecdotes related to her and once again polishing viewers' minds even after the end.
