What do 你 mean 由 "dead" If 你 mean vampire "dead" then it is a slight possibility but not any time soon She cant die die because the whole series revolves around her unless she dies towards the end :p
I don't think she will become a vampire anytime soon. She is one of the stars of the show, it makes it 更多 interesting if she stays human. She cares about two vampire brothers. If she becomes a vampire, I think it would spoil the show...everybody slowly becoming a vamp.....
