(you are a vampire, you just turned into one and you don't remember anything about your past, you wakes up in a laboratory)

You are a little boy/girl looking like the age of 17. You aren't ageing anymore though. You have white short hair and deep red eyes.

someone comes inside and looks at you, he is in a white lab coat and have a infection needle with him

"Hello, seems like you are awake"

he says behind a piece of glass. You can't escape, the door is locked. You’re here to be tested
