In the actual broadcast, Yoo Si Jin and Seo Dae Young talk about the beautiful women in Uruk, saying, “There are many pretty women in Uruk. It’s like Kim Tae Hee is working in the fields while SISTAR is picking grapes.”
When rehearsing this scene, Song Joong Ki asks, “It’s been changed to SISTAR?”
Then Jin Goo and Song Joong Ki play rock-paper-scissors to choose who is mentioned in the dialogue; Song Joong Ki is for AOA while Jin Goo is for SISTAR. Unfortunately for Song Joong Ki, Jin Goo won the match and they went with SISTAR as shown in the drama.
