Where to Watch Undercover High School in the UK

Undercover High School is currently streaming in Australia on Kocowa, and in the US on Rakuten Viki and OnDemandKorea, and its 8/10 TMDB rating reflects what viewers who've already found it know. A tightly focused run that doesn't overstay its welcome.

Part of the current wave of streaming-era originals, Undercover High School follows a path that stands out in a crowded field. Ace NIS agent Jung Hae-seong is demoted after a mission failure. He goes undercover at a high school to locate King Gojong's missing gold, meeting his teacher Oh Soo-ah, who sees him as her lost first love, stirring old heartbreak. Seo Kang-joon and Jin Ki-joo lead a cast that brings real weight to the material. It aired in 2025.

The kind of show you put on in the background and find yourself actually paying attention to.
