Ji Chang Wook didn't force himself on Ha Ji Won.
On the 33rd episode of MBC Monday/Tuesday drama "Empress Ki" (script Jang Young Chul, Jung Kyung Soon, director Han Hee, Lee Sung Joon) broadcast on February 25th, Ta Whan (played by Ji Chang Wook) didn't force himself on Ki Seung Nyang (played by Ha Ji Won).
On this day, Ta Whan tried to have his first night with Ki Seung Nyang as Tanasili (played by Baek Jin Hee) drank. Ta Whan laid her down saying, "Until when are you going to be like this. I want you."
However, Ta Whan was getting closer to Ki Seung Nyang and then hesitated. Ta Whan said, "I will wait until you recognize me first. Even though you're behind me I miss you a lot" as he expressed that he would wait.
Ki Seung Nyang took a breath and said, "You just have to think about regaining the throne." At this, Ta Whan said, "You're the one that made me like this. Don't make me wait too long" and sent Ki Seung Nyang to her chambers.
