The first poster released on the 16th (today) shows Seo Kang-joon showing off his comic book-like visuals as the ace agent of the National Intelligence Service, Jung Hae-sung.

First, Seo Kang-joon is standing in a dark hallway wearing his school uniform, staring straight ahead with a determined expression. His figure holding a gun and radiating heavy charisma in the middle heightens the tension. Also, the face hidden in the shadows brings out the duality of the NIS agent disguised as a student.

Seo Kang-joon receives special instructions as an NIS agent and becomes a high school student and goes to school. While carrying out his mission there, he also gets entangled with the students and spends colorful days. In particular, unexpected events unfold in front of him without pause, which will increase the fun of watching.

The production team of ‘Undercover High School’ said, “The first poster that was revealed put together the contrasting elements of a school uniform and a gun to capture the concept of a National Intelligence Service agent who infiltrated a high school in one picture”, and explained, “The image of Agent Jeong Hae-seong standing resolutely in the hallway in front of the classroom announces the start of the Undercover High School operation.”‘Undercover High School’ is a drama that contains the adventures of an National Intelligence Service agent who disguises himself as a high school student to track down the whereabouts of Emperor Gojong‘s missing gold bars.
