Seo Kang Joon Lives a Double Life in Korean Drama 'Undercover High School'

After three years of hiatus from acting, fans certainly miss Seo Kang Joon's appearance . But don't worry, Seo Kang Joon will return to greet viewers through his latest drama entitled 'High School Undercover' which will start airing tomorrow, February 21, 2025.

Interestingly, Seo Kang Joon will be living a double life which further proves his acting is no joke. He will play the character Jung Hae Seong who is actually an agent of the National Intelligence Agency. 

Under the same name, he goes undercover at a high school to track down Emperor Gojong's missing gold bars. This happens because he made a mistake so he was demoted and became a field agent. 

In living a double life, Jung Hae Seong must be able to hide his true identity as an agent of the National Intelligence Agency. However, Jung Hae Seong experiences a crisis when he meets Oh So A (Jin Ki Joo).  She is a Korean history teacher who teaches in Jung Hae Seong's class and is also his homeroom teacher. 

Coincidentally, Oh So A feels that she has met her first love Jung Hae Seong. But logic says that it is impossible if her first love is still a high school student. Will Jung Hae Seong's double life finally be revealed because of Oh So A? 

Seo Kang Joon is expected to show off exciting action scenes as a National Intelligence Service agent, but on the other hand, he is also expected to be able to show his humorous and childish acting as a high school student. Especially after meeting someone from his past. 

The attention of potential viewers is also focused on the romance that will be depicted with the 'melodramatic gaze' implied through the poster that has been released. Previously, Seo Kang Joon has managed to captivate viewers through various types of drama genres, from action to romance. 

Such as in the series 'Grid', 'When the Weather is Fine', 'Wathcer', 'Something About Us', and 'The 3rd Charm'. Don't miss the Korean drama ' Undercover High School ' which marks Seo Kang Joon's 3-year comeback, will premiere tomorrow, February 21, 2025 at 9:50 p.m. KST.
