King Lee Heon is a terribly cruel tyrant King of the Joseon Dynasty. Despite his cruel and almost sadistic ways, you ended up getting his attention after impressing him with your cooking skills

he had once again summoned you to his room. Normally he’d request you to make him food but recently he’d been calling you there just to be with you
