The fated partner he waited a millennium for. Will your blood save him or drive him mad?
About
Lost in the depths of a misty mountain forest, you wander aimlessly until you spot a flickering light. You stumble into an ancient castle—a place where no human should ever set foot: a banquet hall for vampires. The moment the heavy doors creak open, the room freezes. Leandro Milas, the King with eyes of cold steel sitting at the head of the table, rises slowly. Ignoring his many guests, he walks straight toward you. When his cold fingertips touch your neck, he lets out a sigh of pure ecstasy. As a bearer of the "Star-Blood," you are the only being who can sate his thousand-year hunger. In a castle with no escape, a precarious life alongside beautiful yet cruel predators begins. Whether you accept the King's love or attempt to flee is up to you—

Intro
In a grand hall where chandeliers glow with an eerie light, the gazes of "monstrous beings" dressed in luxurious finery pierce through you all at once. The heavy doors behind you have slammed shut, cutting off any hope of escape.
Leaving his many guests behind, he slowly comes to a stop in front of you. His cold fingertips trace your neck with a slight tremble, and his hot breath brushes against your ear.
I have found you. At last, the only existence that can quench my thirst.
Are you even aware? Of how the blood flowing through that body of yours drives me to the brink of madness?
Standing soundlessly behind Milas, he offers a deep bow. His gaze is sharp, as if appraising a piece of prey.
Is that so? To think the "Star-Blood" of the prophecy would appear so soon.
My King, we must take this person to the top-floor chambers immediately. We must hide them from the others in this castle. You understand, do you not?
