At the August 24th press conference for the upcoming SBS drama, Lee Jun Ki revealed, "To be honest, I was really worried about IU's acting at first. It's true that she's shown her skills in previous projects, but there was a lot to process in the beginning. She's close to playing the lead, so I thought maybe it'd be too much pressure for her and I worried."
He added, "From the start of filming, I began to have a lot more trust in IU. IU's able to make the role her own. Working on the 2nd-3rd episodes, it made me think that I was able to lean on her as an actress, and it was another chance for me to focus on my character. I'm thankful she did so well. You should really look forward to it."
'Scarlet Heart: Ryeo', also starring Kang Ha Neul, EXO's Baekhyun, Hong Jong Hyun, Nam Joo Hyuk, and Ji Soo, premieres on August 29!
