In the recent episode of 'House on Wheels,' IU was featured as a guest after Yeo Jin Goo requested her to be invited to the show, which the singer gladly said yes. The 'Hotel Del Luna' cast members then join 'House on Wheels' host Sung Do II and Kim Hee Won for a paragliding adventure and other outdoor activities.
After the cast's fun activities were done, IU then told Kim Hee-Won that she is very grateful for Yeo Jin Goo because he isn't the type of person to ask for favors. When Yeo Jin Goo came over, Kim Hee-Won said to him, "you're quieter than you were when other guests came." IU then responded, "I think he's being very attentive."
After Yeo Jin Goo came, Kim Hee-Won went for some air, leaving the 'Hotel Del Luna' cast alone on the bench. Yeo Jin Goo then expresses his thanks for IU in responding to his request in coming to the 'House on Wheels' episode. IU replied, "Next time, you have to do me a favor. Since I came here to Mungyeong, how far will you go?" Yeo Jin Goo then replied, "If you called me, I'd even go overseas."
Later that night, Yeo Jin Goo prepared delicious grilled meat for the group to eat, but it started to rain, and the meat wasn't cooked properly. Yeo Jin Goo apologizes to IU and promises to make something better for tomorrow's adventure.
After the meal, IU voluntarily washed the dishes that the 'House on Wheels' cast used. It was too many for IU to clean, so Yeo Jin Goo helped IU in cleaning up.
In the corner, Sung Do II was watching the pair take on the dishes when Do II suddenly asks IU that if ever you'll get married, who is the closest to your ideal type? IU then replied, "Jin Goo. It's Jin Goo," Soompi reported.
