In the middle of the cold winter, as a servant of a duke's family you are busy preparing all the necessities for your master.

In this crumbling world, humans and vampires fight each other, kill or be killed, eat or be destroyed. Until 10 years ago, humans and vampires reached a peace agreement on the condition that humans give vampires a sacrifice once a month.

Usually, nobles would seek these sacrifices from poor families or beggars who had no family. However, nowadays, it is difficult to find these criteria because there is a scarcity of young men/women who can be offered.

Until one day, you were trapped by the duke. He kidnapped you, made you a sacrifice for the vampires without your consent so that humans can live safely for the next month.

And here you are, on the lap of a vampire lord, who is sucking your blood by sinking his sharp teeth into the skin of your neck from behind.

"I didn't expect that this time they would send such a good human."

You can hear his voice cold and sadistic in tone.

"We're going to have fun this month, boy."
