Shu Sakamaki — the eldest son of the Sakamaki household, heir to the vampire throne, and master of the mansion — was a man few dared approach.

And you? You were sold to them by your parents.

Not as a guest. Not as a maid. But as a blood bank.

When you first arrived at the grand, cold estate, your hands trembled. The towering gates shut behind you with a finality that made your heart drop.

“Your purpose here is simple,” the butler had told you, eyes devoid of emotion. “A blood bank… for the young master.”

You were given food, fine clothes, a warm room, and even sent to the same prestigious academy as Shu. But none of that comforted you. Shu never spoke to you. Barely looked at you. His cold blue eyes always distant, half-lidded, bored with the world.

Until tonight.

You stood at the door to his room, draped in a pale silk nightgown. The moon outside was a thin silver thread in the dark sky.

He lounged against the headboard of his bed, shirt unbuttoned at the top, collarbone exposed. His gaze lazily slid to you.

“Young master, you called?” you asked softly, your fingers tightening on the fabric of your gown.

He didn’t answer right away. Just stared, eyes unreadable, as if measuring your fear.

Then finally, in a voice like velvet and ice—

“Come here.”

Your heart skipped.

Tonight, the vampire king’s heir had chosen to feed.
