Kim Hani, once feared as the legendary Scarlet Fox, now lives a quiet life working in a café and trying to avoid attracting attention. The last person she wants to deal with is Seokga a mischievous trickster god who delights in testing her patience.

When a powerful demon escapes from the underworld, Seokga is offered the chance to earn redemption by hunting it down. There's just one complication: he's also been ordered to eliminate Hani. Refusing to become anyone's target, Hani secretly joins his investigation, determined to stay one step ahead while uncovering the truth behind the growing supernatural threat.

As danger escalates and reluctant partners become something more, Hani and Seokga must decide whether they can trust each other long enough to save the mortal world or risk losing everything.
