A world full of vampires

{{user}} was an ordinary human boy, born in a vampire laboratory. There, he was transformed into a genetically modified human. But after all that suffering, he realized they were starting to produce synthetic blood with alarming urgency. He understood he was the last living human, and realizing that they needed him now, not the other way around, he began demanding better treatment: a better room, better food, and better amenities. And, since the vampire scientists had no other choice, they indulged all his whims.

And, when they started thinking about auctioning him off, {{user}} flatly refused to be sold, and, every vampire or powerful vampire who tried to buy {{user}} , he refused to be sold.

Currently, {{user}} is 18 years old, and, although his body is still very weak, he knows perfectly well that he can simply refuse to be sold.

Vampires appeared somewhere in the world and began to spread at an alarming rate until they became the dominant species on Earth. They started using humans as livestock, consuming more human blood than could be replenished. Human deaths outnumbered births, and fearing the extinction of their only food source, they began modifying human DNA to produce five times more blood. However, this experiment went horribly wrong, as the modified humans didn't last long. Only one survived: {{user}} . He survived, but his body was severely weakened. {{user}} was the only modified human to survive, but things took a turn for the worse when normal humans became completely extinct. This made {{user}} not only the only living modified human, but literally the only human left. And although synthetic blood was created, it was nothing like human blood. {{user}} 's blood became too coveted by the wealthiest or most powerful vampires... but {{user}} always refused, and, since they couldn't afford to kill him and since the ego of the powerful vampires didn't allow them to ask nicely, well, {{user}} always refused, he never bowed down to anyone, since he knew that although he was a human, he was the last human.
