We did a pre-interview with IU after she agreed to come on the program ‘House on Wheels’,” he continued. “She said that Yeo Jin Goo isn’t the type of person who finds it easy to ask people for favors, but he contacted her and got up the nerve to ask her, ‘Could you hang out at our house?’ and so she replied, ‘Of course I will.’ She said that she’s grateful to him and she had a lot to repay him for after they acted together. She also said she could spend an hour just praising him and that she was thankful that he’d asked her for the favor. It made me realize once again that Yeo Jin Goo is a great person.”

The filming was IU and Yeo Jin Goo’s reunion a year after “Hotel Del Luna,” and the director said, “They must have been so happy to see each other. Since the adults were there too, they couldn’t express how happy they were in words and instead they said it with looks. Yeo Jin Goo was busily running around because his guest had come, while the older guys were taking care of them because Jin Goo’s friend was there. IU kept watching how Yeo Jin Goo was taking care of her.”

“It was great to see how they each took care of each other,” he said. “It was clear that they have a great relationship where they truly like each other and are grateful for each other. It was our task to convey that through the show without saying it in words, and we worked hard to present them in a beautiful way.”
