The Wrath of the Queen of Hell Ep. 8

Escaping an arranged marriage, the Master of the Jade Hall from the Underworld is reborn in the body of a princess betrayed and murdered by her fiancé. After a drugged night with the Regent Prince, Jade sheds her timid persona and takes the palace by storm. Instead of being the delicate flower the prince imagined, she wields a whip in one hand and a knife in the other, sending enemies fleeing. The prince may think she's meek, but even the ghosts in the palace are terrified of her wild side!
