A few days ago, I started watching “Royal Secret Agent”, a Korean Drama because I was curious. Normally I steer away from not-so-serious dramas because the humor can be quite slapstick but as I waded through the first two episodes, the plot is not too bad. This is about a civil servant in the Joseon Dynasty who reluctantly becomes a UC (like in Line Walker 3) and goes around uncovering corrupt officials.
Accompanying him are a female inspector and his manservant who sometimes unknowingly gets him into trouble. The female inspector poses as a courtesan so that she can infiltrate courtesan houses and get information from the patrons. The UC and female inspector start off disliking each other but soon learn to work together and are beginning to have feelings for each other.
