‘Undercover High School’ has released three new posters.
The new MBC Friday-Saturday drama ‘Undercover High School’ (planned by Namgoong Seong-woo / written by Lim Young-bin / directed by Choi Jeong-in / produced by Neo Entertainment and Slingshot Studio) tells the story of a National Intelligence Service agent who disguises himself as a high school student to track down the whereabouts of Emperor Gojong's missing gold bars.
The released posters showcase the unique characteristics of the characters played by Seo Kang-joon (Jung Hae-sung), Jin Ki-joo (Oh Soo-ah), and Kim Shin-rok (Seo Myung-joo). They exude an aura that is hard to approach, showcasing their strong presence in their respective roles.

First, Seo Kang-joon is seen passing through the students. The phrase “I am Jung Hae-sung. I just transferred here” piques curiosity about what he will encounter as he enters the school. Tasked with a mission, he finds himself entangled with both students and teachers, facing unexpected situations along the way.
Jin Ki-joo, with a gentle smile, says, “Nice to meet you. I am Oh Soo-ah, your homeroom teacher.” As a temporary teacher, Soo-ah prides herself on her love for the children and approaches school life with passion. However, even the always bright and positive Soo-ah carries unspoken emotional scars.
Kim Shin-rok's intense moment also captivates attention. With the line “Let’s see how you play,” he looks down with a fierce gaze, exuding charisma and authority. What events will unfold in this chaotic school, and what impact will his sharp gaze have? The tension rises.
Thus, Seo Kang-joon, Jin Ki-joo, and Kim Shin-rok continue their school life, each carrying their complex stories. Viewers are eager to see what kind of activities they will engage in and are looking forward to the intertwining stories of the three characters.
The production team of ‘Undercover High School’ stated, “The second poster captures Hae-sung standing in front of the school, Soo-ah as a member inside the school, and Myung-joo reigning above the school. Although all three are in the same space of Byeongmun High School, they occupy different positions and hold different meanings.” They added, “Hae-sung is depicted from a high angle as if someone is watching him, Soo-ah is shown at eye level from the students' perspective, and Myung-joo is portrayed from a low angle, expressing the characteristics of each character.”
‘Undercover High School’ will premiere on February 21 at 9:50 PM.
