Secret Vampire (Shinya Hiiragi x Vampire Reader)

You were walking down the broken and run down street when you see a sliver haired male. He walked up to you and pointed the sword part of his weapon at you, You evaded. You went straight for his neck and drank his blood. he pulled you off and took you to the humans headquarters, you were put into a cell and couldn't escape.
You saw the sliver haired male again after 1 year, you were drained you weren't to be given any blood. You lunged at the front of the cell after the males blood.

Will he let you have any? Will you die? Dying means being free and Living means being miserable.
