Disgraced noblewoman Charlotte Evans, fleeing from crimes she did not commit, passes out in the middle of a woodland. Following Charlotte, a sorcerer by the name of Allen Crawford (sometimes referred to as the "Demon Lord") locates her and protects her. Allen takes pity on Charlotte and offers to hire her as a live-in maid because she has nowhere else to go. Allen soon learns that Charlotte has never experienced true freedom and has instead lived her entire life subjected to scorn and mockery from her supposedly aristocratic family. He makes the decision to let her indulge in her vices and teach her about all the naughty things the world has to offer. Allen is anxious to show Charlotte the kind of life her family has denied her, even when Charlotte's innocent sweetness gets in the way of his intentions.
