With the death of his mother—a woman who lived and died as a “mistress”—young Yukishiro Haruka is cast into the lion’s den: the home of the formidable Fujiwara clan. His father, the man who married into this powerful family, is long dead, leaving Haruka utterly alone and besieged on all sides.

The family’s matriarch wants to force him to acknowledge her as his mother. His nominal “auntie” schemes to use him as a pawn to secure the family fortune. His cruel half-sister wants to control him like a new toy. In a house where even the maids dare to mock him, Haruka’s only weapon is a natural, magnetic charm he doesn’t yet understand. He must learn to tread carefully, or he will be consumed by the very people who claim to be his family.
