Actor Seo Kang Joon stars in the TV series ”Undercover High School” and the fourth teaser video has been released... ”I never knew he looked so good in a uniform” (video included)

The fourth teaser video for "Undercover High School," which depicts the daily life of Seo Kang Joon, who never knows where he'll go, has been released.
MBC's new Fri-Sat TV series "Undercover High School," scheduled to premiere on the 21st, is about high school students who are searching for the whereabouts of Emperor Gojong's missing gold.
The TV series depicts the chaotic high school life of a National Intelligence Service agent who infiltrates the school disguised as a police officer. The fourth teaser video released on the 17th shows Jung Hye Seong (Seo Kang Joon)'s chaotic cancellation.
The book contains the story of a man who is a member of the National Intelligence Service and must disguise himself as a high school student in order to carry out a mission, leading an unfortunate (?) double life.
First of all, Hye-sung, who exudes coolness, is depicted relentlessly pursuing someone, befitting an agent of the National Intelligence Service, which is quite eye-catching.
However, this is only temporary, and the sight of him going to school in his uniform gives us the impression of strong determination.
From her first day at the new school, Hye-sung attracts the attention of her classmates and makes a spectacular entrance.
Meanwhile, Ahn Seok-ho says, "Never cause any trouble with students."
The urgent voice of the team leader (Jeon Bae Soo) joins in, drawing attention. However, Hye Sung is standing in front of a suspicious building with her classmate Lee Dong Min (Shin Jun Han).
She has troubles with her teacher Oh Soo Ah (Jin Ki Joo) and spends her days in a state of unrest. Furthermore, Hye Sung is dragged out by the troublemaker Park Tae Soo (Jang Sung Bum).
Thus, Jeong Hye-sung faces the inevitable fate of becoming a high school student overnight. How does Hye-sung, who has suddenly found herself at school, interact with the students and teachers?
It will be interesting to see how the two of them get entangled, and whether he will be able to find the whereabouts of the missing gold without revealing his true identity until the very end.
Expectations are also high for the colorful acting displayed by Seo Kang Joon, who will be playing the role.
I am.
