Bond By Blood; In love With A Vampire

He is a vampire. She is a witch.
He has lived for thousands of years.
She is only thirty.
But her blood is both a cure for vampirism and a deadly poison.
Lif felt her world breaking apart when she learned of the secret or rather a curse behind her mother's bloodline. They were witches and they were cursed. She found out that none of the women in their family had lived past thirty- two years. Having realized that she had only two years left, she decided to live her remaining years to the fullest, enjoy her life while she could without regretting later. So she went to a club and get herself drunk, and that was where she met him; a cold blooded vampire who was haunted by his past.
Fate entwined their paths — but love might not be enough to save them from the curse and guilty they both carry.
What do you think would be the end of them both?
