If you write about a vampire and someone guesses his secret, what would you say about his becoming one?Sorry I keep asking questions like...

In light of the additional information you have provided,
and assuming that the girl is also in love with the boy, the usual ways these stories
wind up is either the girl loves the boy so much that he lets him bite her so that she,
too can be a vampire, the girl leaves the boy, even though she loves him, the boy tells
the girl he is a vampire, but then leaves her for her own good, or they both kill
themselves like Romeo and Juliet, choosing death as opposed to living
apart.

Ho hum. Been there, done that. Why don't you get
really creative and make up a totally different story and ending? I will offer some
possibilities, and you can take it from there! Use your imagination and write something
really out-of-the-box:

1. The girl just so happens
   to be a chemistry nerd and decides to go to work to find a formula that can turn the boy
   back into a normal person.


2. The girl happens to be a
   biology nerd and finds a special type of substance that the boy can drink that takes the
   place of blood - some sort of compound that satisfies his need for blood, without being
   blood.


3. The girl and boy both become astronauts and
   colonize another planet, where vampirism cannot survive in the planet's atmosphere, and
   they live happily ever after.


4. The girl wakes up and finds
   it is all a dream and no one is a vampire, neither the boy, her mother,
   etc.

You get the idea! Good
luck.
