The second teaser video of 'Undercover High School' featuring the chemistry between Seo Kang-joon and Jin Ki-joo has been released.
The new MBC Friday-Saturday drama 'Undercover High School', which airs on the 21st, 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 second teaser video released on the 6th features the chaotic first meeting between Jung Hae-sung (played by Seo Kang-joon) and Oh Soo-a (played by Jin Ki-joo).

Soo-a is momentarily captivated when she sees Hae-sung drinking, but her mood quickly shifts to anger when she sees him appear as a new transfer student. Hae-sung retorts, forgetting his duties as a student, saying, "Aren't you also not that great?" The bickering between the two from the start makes their meeting very interesting.
However, Soo-a begins to harbor suspicions about Hae-sung, saying, "It's not just that he's strange." She goes out at midnight to find something, and the urgent tone of Team Leader Ahn Seok-ho (played by Jeon Bae-soo) saying, "What if you get caught by the teacher?" suggests that something has gone wrong during the operation.

Attention is focused on Hae-sung's thrilling undercover operation, which is filled with twists and turns.
Meanwhile, as the two grow closer, they slowly ignite a sweet yet dangerous romance. The pink chemistry between Hae-sung and Soo-a, which goes beyond the teacher-student relationship, is expected to enrich the drama.
While the first teaser showcased Seo Kang-joon's impressive performance, the second teaser depicts various moments of Seo Kang-joon and Jin Ki-joo's playful interactions, raising viewers' anticipation for the romantic comedy.
Meanwhile, 'Undercover High School' will premiere on February 21 at 9:50 PM.
