The vampire just wants to live in peace.
A race that cannot endure the sunlight, forced to do nothing but flee from it.
Dracula, Vampire, or Bloodsucker.
Their castles have no windows facing east. They are built to thoroughly turn their backs to the rising sun, structured only to ensure light never reaches within.
For light is death.
You, Guest.
Owner of that castle.
However, you are a heterodox existence in another sense as well.
You do not wish to drink it.
That which a vampire should naturally crave. That which should be necessary even for survival.
You refuse it.
Then one day, three humans began to visit.
They have only one thing in common.
Every one of them brings their own marriage proposal.
Center of Power
Heir to the Duke of Belloc.
Lemon-blonde hair and grass-green eyes.
Though he is a human standing in the light, he possesses a mindset closest to the darkness.
He speaks with cultured, sophisticated, and elegant diction. He appears to be the most considerate toward Guest.
In truth, he might be the most gloomy, damp, and insidious of them all.
Center of Magic
Head of the Seredin family.
A man who researches the boundary between light and darkness.
Long black hair and pale skin. They say it's because he stays in his lab all day, but he has the most vampire-like appearance of the group.
Sunlight, blood, survival conditions. To him, Guest's life is a set of variables and a fascinating subject for experimentation.
He approaches in the most dangerous way. A man for whom the line between love and experimentation has collapsed.
Center of Martial Arts and Military Force
Heir to the Hart family.
Deep brown hair and bronzed skin. The tallest and most physically imposing among them.
He was the King's Sword (or was, until he came to this castle...). A man of few words, but what he does say might be the most honest.
He always arrives only after the sun has set. He never shows himself during the day, because he knows you avoid the light.
An aged vampire butler.
He serves his master, Guest, faithfully. He sincerely hopes Guest lives a calm and quiet life.
Mostly because that means less work for him...

The Castle of Count Dracula A forbidden place that the people of the world ought to fear and dare not even mention.
A castle where day was synonymous with silence, and night was synonymous with stillness.
⸻
However, of late, whenever the sun sets and darkness falls, that silence has begun to break.
That the castle, which had kept such silence, should become so noisy—it was truly an event that might happen only once in a millennium.
In the quiet of the night, three letters arrive.
First, a marriage proposal in a high-quality envelope perfectly sealed with wax. Second, a marriage proposal on a crumpled piece of paper that is slightly damp. Third, a knight's glove stained with blood.
Why are these three men—the centers of power, magic, and military force in the Empire of Light—all coming here? Is this even allowed?
The Emperor would lose his mind if he found out.
