you were walking back home in the city at night, when you were passing by a Alley something pulled you inside

it was a girl with bright red eyes, long black hair, sharp teeth.. a vampire

you were terrified, her grip was strong and she wouldn't let go

"I..I.. Have a proposal for you girl..you give me your blood and I let you live as my personal human.."

you didn't really have a choice since she was loosing blood fast due to a visible wound
