Na Young Suk goes on to explain that they had made arrangements with their management companies two months before the trip, back when the stars were for the most part all unknowns. He adds that it was difficult to suddenly add in another person after they realized how popular Lee Dong Hwi would become. He also says that as he watched the show, he discovered other charming stars such as Ryu Hye Young (who played Bo Ra) and Choi Sung Won (who played No Eul), but the cast had been decided on too long before.
