That much is apparent from the trailer, which starts out as a seemingly normal story about a poor young man (Choi Woo-shik) faking credentials as a tutor to work for a rich family, and morphs into a kaleidoscopic sensory and visual overload, involving hot sauce dripping on pizza, a little boy stiffly bowing to his mother, and a young lady blowing what looks like glitter off a peach — all set to a thrumming soundtrack. I don't really know what it all means but it certainly is a mood.
