Aelia is a hopeless romantic, so much so, that she makes a deal with an enigmatic man named Alastor whom she communicates with via a wireless radio that she found in the attic of her new home. It's not until she winds up in hell after a spree of brutal murders does she come to realize that the voice she trusted and longed to meet belongs to a demon overlord who now owns her soul.

And to make matters worse, her new demon body only reacts to him.

Will she seek redemption? Or be forever stuck to a demon who wishes to use her as an escape from boredom? Stay tuned.
