What happens when a human boy switches bodies with a dead girl? All Hell breaks loose.

Oh Sehun's a young writer prodigy whose love for the living is practically non-existent. He hates his parents, his teachers, his classmates (and the school's entire ogling female population), his neighbors and their obnoxious pets (that walks and talks and clings), passing pedestrians, dogs, cats, flowers (?) and happy living beings. Bah. They drive him nuts.

For a dead girl who's been dead for almost 5 years, Lee Jieun is still stuck at the tender age of 18. Favored by the Devil, she's a perky, witty and clever soul who stood out like a sore thumb in Hell. So when she finds a human whose time on Earth is ending soon, she offers him a deal and gets herself tangled in a game of the living and the dead.
