They'll do anything to outsmart each other. Anything, except fall in love.

In this delightful Korean contemporary fantasy, a fallen trickster god must pair up with a coffee-slinging, shapeshifting fox to track down a demon of darkness before it devours the mortal world.
Kim Hani - the once-terrible gumiho known as the Scarlet Fox - spends her days working at a cafe and trying not to let a certain customer irk her.
Seokga - a trickster god thrown from the heavens for his attempt at a coup - spends his days hunting demons and irking a particular gumiho.
When a demon of darkness escapes the underworld, and the Scarlet Fox emerges from hiding before quickly vanishing, Seokga is offered a chance at redemption: kill them both, and his sins will be forgiven.

But Hani is prepared to do anything to prevent Seokga from bringing her to justice, even trick her way into his investigation. Anything, that is - except fall in love . . .
