Iris is a  schoolgirl who wakes up to find that she is to marry a cold strange man,  also a vampire named Dylan . Not ready to accept her fate she tried to run away but was stopped by her father. It was because of a promise made by her ancestor a hundred years ago that she had to marry when she would turn 18. She was not an ordinary girl but a spirit who has reincarnated after 100 years . Along with the vampires there are werewolves who are after her as she is the only person who can give birth to a powerful hybrid but at the cost of her own life. Spirits will not live more than 25years.
