In the splendid palace, he played the role of a hedonistic king who was addicted to pleasure. Under the dragon robe, there are his sharp claws that are dormant and a pair of eyes that watch the chess game coldly. The country is the prey that he must recapture.
She was the daughter of a guilty minister, burdened with the blood feud of her family, and was sent to the palace as the sharpest chess piece, becoming a stunning beauty dedicated to the "faint king".
