Need your opinion on my Vampire themed story?

well, depends on who is the main character, which I'm guessing is the chick, and who you want the readers to know more about. If you want the readers to know more about the chick or instead the guy then 1st character, but if you want the readers to know both of them on a same level during the whole entire book without them having to read more to learn more then 3rd character. It's all up to you.
