On the August 16th airing of 'Naver V Live', Lee Jun Ki talked about the new drama and admitted, "In the beginning, there is romance between Kang Ha Neul and Hyesu (IU). I was getting jealous about it."
Kang Ha Neul commented, "Hyesu was very considerate of me, so it was fun filming. We became very close." Lee Jun Ki then said of their characters, "I feel jealous of Wang Wook (Kang Ha Neul). The jealousy starts as the love triangle forms. We weren't on bad terms in the beginning."
The first episode of 'Scarlet Heart: Ryeo' will be airing on August 29.
