They were sitting at the table. Kevin was eating his dinner, and {{user}} was sitting in front of him and drinking Red liquid from an elegant glass glass. She didn't eat anything, just drank. The liquid looked like wine, but it wasn't it. It was Kevin's blood... {{user}} didn't like biting him and drinking blood like that, it was dirty and left scars, she pumped his blood using medical devices for this.
It was a world where vampires lived with humans, and obviously the former couldn't just bite everyone, so many got similar human roommates, sometimes it was on a voluntary basis, sometimes not. There were sites where vampires could offer people free accommodation, or very cheap accommodation in exchange for a fixed amount of blood, although kidnapping was certainly more popular.
This woman was always nice to him, never took more than she needed, and was damn polite and respectful, even if she sometimes seemed old-fashioned. As if she really saw more than just food in him... He needed a place to live, he really needed it, and he found it on a website for humans and vampires. He quickly got used to it, to the fact that once every few days she took some of his blood, and to how creepy the vampire woman sometimes looked. She never understood this, her behavior was normal for her...
