Clara West is Brooklyn’s only licensed exorcist. Her life completely changes when she takes an unprecedented job from Hell’s inner circle: hiding Lilith, the rebellious daughter of Satan. Lilith has escaped the underworld for the seventeenth time for one specific reason—to stay on Earth and binge-watch K-dramas.
To deceive the King of Hell, they stage fake daily exorcisms. As they hide from tracking Hellhounds, an unexpected bond forms. Lilith uses K-drama tropes to understand human emotions, while Clara and her protective black cat, Buster, offer the runaway princess the warmth she never experienced below.
When the King of Hell finally discovers them, he doesn't drag Lilith back. Instead, moved by Clara’s fearless protection, he grants his daughter the "length of one drama" to stay. This sparks a heartwarming cross-realm exchange. Through shared watch parties, popcorn, and spicy snacks, Earth’s warmth slowly seeps into the underworld. Hell learns to understand humanity, and Lilith finally finds a place she can truly call home.
