In 21st century Korea, half-demon Jaekyung barely makes a living managing a plain restaurant.
One day, a man, extremely good-looking but with a tacky style, shows up and says he will take away Wonyoung, who is Jaekyung’s precious family.
Moomyung (meaning unidentified) always emits a scary aura and behaves in a scary way, plus he has already attached himself to Jaekyung’s home, and idly loafs around.
Jaekyung thinks Moomyung is deplorable and Moomyung is just dumbfounded that half-demon Jaekyung defies him without fear…
At the same time, Jaekyung, who ends up often having erotic dreams after Moomyung appeared, is confused because he now even sees overlaps of dream Moomyung in real life.
The childish romance of a half fox demon and a great demon!
