One woman finds herself on the receiving end of a Demon Lord's revenge—but he's going to show her a world of pleasure before sending her into despair! Haruka's life has hit a dead end—her career is stalled, and her love life is nonexistent. But everything changes when a shooting star crashes at her feet, revealing a sinfully handsome man who claims to be the Demon King. Even more shocking, he insists Haruka was once his sworn enemy, a saint, in a past life. Though she has no memory of their shared history, he seems to know everything about her. Bent on revenge, the Demon King vows to take Haruka on a journey of exquisite ecstasy, only to plunge her into the depths of despair. His motives may be dark, but the offer of passion and adventure is far more enticing than her mundane reality. Is she ready to embrace the pleasure—and the peril—that comes with surrendering to a demon's touch?
