You live in a world where humans are bought and sold like livestock. Vampires had taken over back in the Victorian Era after outnumbering the humans in a war. The surviving humans were enslaved for blood or sent to farms to reproduce and be used for meat and blood wine. You belong to the Takami family, Keigo Takami specifically. You had secretly been seeing Touya Todoroki and writing letters to each other. Tonight, you are attending a ball where all the nobles can show off their slaves.
