Actor Seo Kang-jun is showcasing a one-man show with 'life character' Jung Hae-sung.

Recently, Seo Kang-jun has been praised for his detailed acting while playing the role of National Intelligence Service ace agent Jung Hae-sung in the MBC Friday-Saturday drama 'Undercover High School', which is currently airing. We took a 'zoom-in' look at Seo Kang-jun's performance as he freely transitions between dazzling action, emotionally resonant human scenes, and delightful comedy.

▲ Action: Breaking the limits of space

Seo Kang-jun presented a variety of action scenes through 'Undercover High School'. He climbed onto a car while racing to retrieve a statue that was being illegally trafficked and utilized water bottles in a restaurant to easily fend off problematic customers. He displayed refreshing action as he stormed into an illegal gambling den, showcasing a superhero-like presence.

In particular, in the 11th episode, Seo Kang-jun, who was falsely accused of murdering Director Kim (played by Lee Seo-hwan) and was being transported, showcased his skills as a National Intelligence Service ace while fighting inside a cramped van. It was action acting that broke the limits of space, possible only because of Seo Kang-jun.

▲ Human: Emotions completed with detail… Overwhelming acting skills

Seo Kang-jun's emotional acting is always refreshing. He builds the narrative by constantly altering his gaze, expressions, and voice. The scenes where he comforts Dong-min, who was suffering from school violence, and scolds irresponsible adults resonated deeply. He expressed the complex emotions he felt while suspecting team leader Ahn (played by Jeon Bae-soo), who was as close as family, and eventually dispelling the misunderstandings.

Seo Kang-jun, who met his father's skeleton for the first time in 20 years in a hidden space within the hospital, depicted the scene in detail with a cold, rigid expression, eyes filled with uncontainable anger, and trembling lips as he suppressed his emotions, captivating the screen even without dialogue.

▲ Comic: Clever dialogue tone… Perfect balance of pacing

Seo Kang-jun's role in maximizing the charm of the comic action drama was also significant. He skillfully maintained a perfect balance of pacing with a clever dialogue tone, smoothly carrying the narrative.

Among them, the election campaign song for the student council membership, called 'Byeongja Byeongjeong (the pride of Byeongmun and Jung Hae-sung)', expanded in popularity as a challenge. A meme even emerged saying, "Why is Seo Kang-jun pushing himself so hard?" reflecting both his acting and dance skills.

Meanwhile, the final episode of 'Undercover High School', starring Seo Kang-jun, will air today (29th) at 9:50 p.m.
