MBC's drama "Undercover High School" has released a new behind-the-scenes video. This comedy action series features a National Intelligence Service agent who goes undercover as a high school student. Seo Kang Jun plays the lead role of Jeong Hae Seong, who is on a mission to find Emperor Gojong’s missing gold. In the making-of video, Seo Kang Jun and his co-star Jin Ki Joo showcase their professionalism and chemistry. Jin Ki Joo expresses her thoughts on a scene where her character, Oh Soo Ah, comforts Jeong Hae Seong. Seo Kang Jun listens carefully and offers advice, encouraging her to follow her instincts in the scene. The director supports their discussion, agreeing that not holding hands in the scene makes Soo Ah appear more fearful. Before filming begins, the cast shows their camaraderie, with Park Se Hyun taking fun polaroid pictures of them.

"Undercover High School" airs every Friday and Saturday at 9:50 p.m. KST.
