A crazy emperor with possessiveness engraved in his bones married a sickly and cruel prime minister's daughter. On the surface, the two of them are the emperor who forcibly marries a commoner's daughter, but in fact they are madly in love with each other, running in both directions. Externally, they join forces to kill all those who stand in their way; internally, they test each other, bite each other, and possess each other. In the end, they discover that she is crazier than him, and he is more ruthless than her. They are a match made in heaven, and they will part ways until death.
