A delightful romantic Korean contemporary fantasy tale - a quest to track down a demon of darkness before it devours the mortal realm. Two bickering immortals. One chance to save the world.

Kim Hani - the once-terrible gumiho known as the Scarlet Fox - spends her days working at a café 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 briefly emerges from hiding, 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 . .
