After an office worker is reborn as Everia Oberon, a romance novel villainess destined for an evil life and a tragic death, she decides to skip the drama by retiring to the countryside. Having moved to a frigid region full of nonflammable wood, Everia calls on archmage Theoharis to warm her home with his azure flame… not realizing that she’s bound herself to a lifelong contract! Now that she’s master of a bloodthirsty (but breathtakingly handsome) demon dog, can she kiss the quiet life goodbye?
