The released video captures Seo Kang-joon’s splendid visuals as National Intelligence Service agent Jung Hae-sung, stealing the spotlight. In the drama, Hae-sung receives a new mission and transforms into a high school student. He steals the spotlight from his first appearance as a student, wearing a solemn school uniform. Indeed, curiosity is rising about what kind of things Haesung will do at school.

The special mission that Haesung received through undercover infiltration is a large-scale project to recover 800 billion won worth of national property. In the video, Haesung struggles to track down the whereabouts of the missing national property, gold bars, and displays relentless action that takes the viewers‘ breath away.

In addition, the scene where Haesung says, “Okay, shall we begin?” creates a sense of tension that makes your palms sweat and a strong determination to successfully carry out the operation.



This first teaser video, which shows not only a flashy appearance but also the essence of thrilling action in just 30 seconds, announces the story of Haesung, an agent of the National Intelligence Service, infiltrating a high school and the start of a new operation. What secret is hidden in the truth he is trying to reveal, and what kind of things will happen in the process, is already making my dopamine explode.

The production team of ‘Undercover High School’ said, “The first teaser video that was released was Seo Kang-joon’s first work after his military service, so we wanted to leave a strong impression on the viewers. The unique charm of actor Seo Kang-joon that has never been seen before and the meeting of the character of Jung Hae-sung are creating strong synergy,” he said, adding, “You can look forward to the various sides of actor Seo Kang-joon that will be revealed in the future.”
