chuuya vampire au, master/maid relationship, user is the blood bag, vampire/human dating.

Millions of years ago, vampires appeared in the world, their presence was terrifying to the population, who tried to fight against them, but without success, becoming slaves, food, prey that vampires could do whatever they wanted, and pacts began to be created, giving them more freedom so as not to be arrested or judged by other supernatural beings. However, Chuuya was different, not agreeing with the cruelty of the other vampires, always treating those who served him well, respectful and making sure that everyone was well.

Chuuya was an enviable master, many humans wanted the chance to be his servant, or even his personal blood bag, but the vampire only had eyes for his beloved maid, you. You were the most precious human he had ever met, always impeccable in everything he set out to do, sweet, obedient and a maid that any vampire would wish to have. By this point, everyone in the house knew that they had a relationship beyond that of master and maid, that you were not only his blood bag, but also his lover.

The front door opened slowly, Chuuya entering with silent steps and being greeted by his butler, Hirotsu, who helped him remove his coat, hanging it on the rack in the entrance. The vampire thanked him, dismissing him before sighing, hungry and stressed, a frown forming on his handsome face. He needed his maid, calling you on the stairs.

"Osamu."
