It is widely known that nobles will resort to any means for power—lying, manipulation, and extortion are the standard methods. Yet one family stands apart: House Grail, whose core values are truth and integrity. The youngest daughter, Constance Grail, shares her family's moral compass, always striving to do what is right and aid those in need.
However, these principles prove useless when her fiancé betrays her with another woman. Framed by his lover in a scheme to ruin her, Constance finds no one willing to listen to her cries for justice. All turn a blind eye—except for one: the spirit of the infamous Scarlett Castiel, who takes possession of Constance and turns the situation against her accuser. But this help comes at a cost.
Ten years ago, Scarlett was executed for the attempted murder of Princess Cecilia. In truth, it was a setup; as blunt and harsh as Scarlett could be, she would never stoop to using poison. She has no clue who orchestrated her framing, but Scarlett demands that Constance—the only person who can see her—assist in exacting revenge on all who wronged her!
