Yoon Si Yoon is finally back from the military and he's hard at work filming his comeback fantasy sageuk drama Mirror of the Witch. He and his talented leading lady Kim Sae Ron recently took a break to pose for Cosmopolitan and talk about what it's like to work with each other on set. 

In the interview for the magazine, Yoon Si Yoon talked about working with talented actress Kim Sae Ron, saying, "I really like the expressions of actress Kim Sae Ron. Kim Sae Ron's expressions fill your eyes with innocence and sincerity, so when we film, she creates this realistic vibe that allows you to truly believe in the situation. We're filming a scene in which Kim Sae Ron departs, and I naturally get immersed to the point that I actually become sad."

Kim Sae Ron said about Yoon Si Yoon, "When acting with oppa, I feel like we are communicating with each other, which I like. I feel like we are acting together and we are naturally communicating, so I'm grateful." Sounds like the couple will have amazing chemistry in their upcoming drama!

Mirror of the Witch reimagines the life of famed Joseon doctor Heo Jun (Yoon Si Yoon) with a fantastical twist. In this version, he is a brilliant and ambitious man struggling to overcome his poor background. He does his best to help the people around him until one day he discovers and falls in love with cursed princess Seo Ri (Kim Sae Ron).  Princess Seo Ri is the daughter of royalty. When the queen (played by Jang Hee Jin) is unable to have children, she makes a deal with a wicked shaman (Yum Jung Ah) and conceives twins, a boy and a girl. The daughter is cursed to have a frozen witch's heart, and her family abandons her, keeping her existence secret. She turns from a young princess into a white-haired witch — until she has a run-in with Heo Jun. Kwak Si Yang, who you may remember as the handsome Cordon in Oh My Ghostess, will play second lead Poong Yeon. 

Mirror of the Witch will premiere on DramaFever after the conclusion of Ms. Temper and Nam Jung Gi. Add the series to your queue below!
