His Duchess is a Ghost

On her wedding day, Alena was murdered. As she took her last breath, she learned from her assassin that her own groom was behind her death. Consumed by a burning desire for vengeance, Alena made a dying vow that she would never leave unless she dragged her groom to hell with her. Miraculously, Alena's desire came true. She became a ghost - a ghost with a mission. She must fulfill her vow of vengeance, or she would transform into an evil, mindless phantom, doomed to wander and haunt the mortal world forever.
