Eng Sub 25 Top: Secretly Greatly Korean Movie

Early in the film, Ryu-hwan (as Dong-gu) is trying to maintain his idiot persona. He pees in the town square while waving at his landlord, Mrs. Moon. The English subtitles perfectly capture the villagers' horrified sighs vs. Dong-gu’s cheerful "Hello!" This sets the tone: this is not a serious spy thriller (yet).
