However, one family is exempt from this generalization: House Grail, whose main tenets are truth and integrity. The youngest daughter, Constance Grail, is just as moral as the rest of her family, believing in always doing the right thing and helping those in need. However, these ideals do not help her when her fiancé cheats on her with another woman. Framed by his lover in the hope of her downfall, Constance's pleas for justice are ignored. Everyone turns a blind eye except for the spirit of the infamous Scarlet Castiel, who possesses Constance and turns the tables on her accuser. However, this aid doesn't come without a price. Ten years ago, Scarlet was executed for the attempted murder of Princess Cecilia. But this was actually a setup; as blunt and harsh as Scarlet could be, she would never stoop so low as to use poison. She has no idea who orchestrated her incrimination, but Scarlet demands that Constance, as the only one who can see her, help her exact revenge on all those who wronged her. See less
