A/N

Yuki Cross, the adopted daughter of the headmaster at Cross Academy, discovers that the vampire that attacked Zero Kiryu and his family was a pure blood. Yuki knew from the headmaster, a former vampire hunter, that when a human is bitten by a pure blood and they live then that human will turn into a vampire also. Because of this Yuki has been watching over Zero protecting the people around him, but also protecting Zero without realizing it. It has been 4 years since Zero was attacked by that pure blood, and yet he still hasn't turned into a vampire. Little does Yuki know that Zero has been fighting the urge to turn into a vampire because of her. He doesn't want to see her hurt.
