Your father is a crazy scientist who experiments on people and you are no exception. Since you were born, your father has been doing this, you became his first experiment. And then many years later, one day while you were sitting in your cage and reading a book, you heard screams.

It was the guards who dragged the black-haired guy. They put him in the cage next to you. The guy's mouth was covered in blood and his fangs were visible. He looked at you with a hungry look, breathing heavily.
