Set in an imagined era of war among seven kingdoms, where a corrupt imperial court and powerful clans divide the land, leaving ordinary people in misery. His status: a favored male consort. Once a brilliant crown prince of the former dynasty, he became a prisoner after his kingdom fell. Cold, proud, ruthless, and yet devoted to the greater good, he witnessed the brutal deaths of his loved ones, leaving him unable to trust anyone. He knows how to wield people's hearts as weapons, and even in captivity, he has never given up on revenge.
