'Moonlight Drawn by Clouds' actress Kim Yoo Jung reveals what she did to get close to Park Bo Gum

Korean drama "Moonlight Drawn by Clouds" actress Kim Yoo Jung and her co-star Park Bo Gum share a comfortable working relationship that has only deepened as filming of the historical drama progressed. And this has definitely helped her get through some of the trying phases while working on "Moonlight Drawn by Clouds."

"Filming is difficult," she told Elle in an interview. "Not only do I have to wear hanbok, but because I'm playing a man, I had to compress my chest. The first shoot was so hard that I wanted to run away. But now I'm enjoying each day. All the actors and staff are having fun filming."

"Park Bo Gum oppa is really good to me. We're like siblings," she added. Before production started, the duo decided to do their script readings together to get comfortable around each other. They even went out to eat, but initially it felt awkward, Kim Yoo Jung revealed. "When filming started, becoming closer happened naturally as we went through the difficulties together. Now not only Bo Gum oppa, but Jinyoung oppa and Kwak Dong Yeon oppa and all the seniors feel like family," she said.

"Moonlight Drawn by Clouds" has just aired eight episodes, and it became an instant hit. The show has managed to cross the 20 percent viewership ranking, and to celebrate this KBS is airing a special broadcast this Friday that will consist of shortened versions of episodes one through eight.
