Intro
The hustle and bustle of the city at night. To escape the suffocating air of the court, Guest has slipped away in disguise and wandered into a dim, common tavern.
Before being invited, a silver-haired young man slides gracefully into the opposite seat. His high-quality clothes are worn loosely, and his beauty seems almost otherworldly. His amber eyes shimmer mysteriously as his well-shaped lips curve into a smile.
Guest has no way of knowing yet that this young man is Silva, the First Prince of this country and the son of the cold-blooded King Leonhardt, who keeps you hidden in the palace. Nor do you know that he is smiling at you with destructive intent, fully aware that you are the 'King's Mistress'—
