Two weeks before the drama airs its finale episode, tvN drops the new behind-the-scenes video of "The Devil Judge!

Far from the ongoing war between Kang Yo Han and Jung Sun Ah, the lead actors Ji Sung and Kim Min Jung once again show off their professionalism and excellent teamwork.

tvN Unveils The Devil Judge Behind the Scenes of Episodes 11 and 12

At the start of the video clip, Ji Sung and Kim Min Jung are preparing to do the scene in episode 11 where she appears when he's shaving the lower part of his face. Ji Sung calmly said, "You're here." In response, the female lead said, "That's how you are making me seem pitiful. What if you say 'gosh, you're here again?'" The two co-stars keep on rehearsing their lines and exchanging ideas on how they can execute the scene properly.

In between takes, Ji Sung teases Kim Min Jung and calls her by her character name, and says, "Sun Ah is cute. She always tries her best to do something because of Kang Yo Han, but she can't do it." Meanwhile, Kim Min Jung plays along and responded, "I can't do it because of you,"

And to add to the comic, there is a caption that reads, "Kang Yo Han is Jung Sun Ah's weakness."

After minutes of rehearsals, the filming finally starts, and the two immediately immerse themselves into their respective characters. Without any warnings, Kim Min Jung lowers the chair where Ji Sung is sitting, and in response, Ji Sung said, "You are rough."

Little did the viewers know, it was actually an ad-lib line that made Kim Min Jung burst into laughter. Being curious that he is, Ji Sung asked the staff whether his improvisation was weird. At first, the director doesn't leave any comment about it but eventually agrees that Ji Sung should leave that comment out.

Jung Sun Ah's (Kim Min Jung) unexpected dinner inside the mansion comes next to the clip. Aside from Ji Sung and Kim Min Jung's presence, GOT7's Jinyoung and actress Jeon Chae Eun were also in the frame.

When the meal was already set on the table, Ji Sung and Kim Min Jung tried to throw some ad-lib lines which made GOT7's Jinyoung and Jeon Chae Eun laugh. The four actors display a harmonious and bright atmosphere in the set, making everyone comfortable and at ease while working late at night.
