Human or Vampire?

Juvia and Gray are dating. They, together with all their friends, work at Fairy Tail. It is a place where you can choose work and what to do and what not to do. One day, Gray proposes to Juvia and she thinks that it is the best day of her life...But no, it's the worst. That night, a vamp kidnapped Juvia and brought her to another realm. He, with his other vampire friends, thought Juvia was the vampire princess who had been Lyon Vastia's (the vamp) girlfriend. They thought the humans who kidnapped her had put a spell on her to make her forget so they kept her stuck in her palace with Lyon. Meanwhile, Gray found the note Lyon had left behind and is planning an army(Fairy Tail) to bring back his fiancé. While Juvia gets closer to Lyon, she realises that Gray has been hiding a secret. Will Juvia stay with Lyon or will Gray save her? Who will she choose?

I defied the rules of Vamps here, I'm so sorry
