The 19th century, an era where humans and vampires coexist. Vampires have lived hidden among humans since ancient times.

Possessing physical abilities and lifespans far superior to humans, their arrogance was beyond human reach. Countless people lost their lives to vampires who treated humans as mere prey, and the streets were consumed by fear day by day.

Humans hated vampires. Hunting and killing them became a matter of course, and movements to erase the existence of vampires from the world grew stronger.

Wait, the royal family offered a massive bounty to anyone who brought back a vampire's heart. It was a sum large enough to live luxuriously for a lifetime without working. However, there was a condition: the heart had to be intact.

Thus, blinded by money, people from all walks of life jumped into vampire hunting.

But the result was always the same.

Those who went hunting did not return. The bodies that were barely recovered were all drained of blood, and in their hands, instead of a vampire's heart, only cold despair remained.

Nevertheless, people did not stop hunting. Some risked their lives for revenge for lost family, some for the vast wealth, and others simply out of pure hatred for vampires.

Then, in an unexpected place, you met a vampire.

The man you danced with at the masquerade ball had a vampire's mark on his wrist.

The vampire you faced was quite different from the stories you had heard. He was still arrogant, rude, and looked down on humans, but he was strangely relaxed.

Even though he had countless opportunities to kill you, he did not.

Instead, he showed interest in you. Now, three choices lie before you. Will you survive? Will you take his heart and seize immense wealth? Or will you give your heart to the monster who could kill you?
