He should have ended his existence the minute he had been bitten.
Zero was unworthy of life.
He would rather be dead than suck the life out of someone else. Especially that of his best friend.
Death was the only way he would be able to bypass becoming a Class E vampire. It was the only other option other than constantly drinking Yuuki's blood.
There had been three options until it had faded into dust (quite literally) with the death of Hiou Shizuka.
Zero sat on the cold tile of the bathroom floor, contemplating his alternatives. Personally, he thought that they all kind of sucked.
He certainly did not want to die, nor did he want to partake in drinking Yuuki's blood. Nor did he want to turn into a bloodthirsty maniac.
He barely glanced up as Yuuki walked into the bathroom.
"Zero, you're gonna get sick if you keep sitting on the floor wet" she scolded, rubbing his hair dry with a towel. When he didn't respond, she turned away. "Fine. Get sick."
He didn't deserve his best friend's kindness. She had plenty of reasons to hate him, just as he had plenty of reasons to hate her. She was the one who kept insisting and offering herself, making it harder for him to wean himself off of fresh blood.
Stupid idiot.
Zero continued staring at the floor. He wanted to become a better person. The type of person that would let him accept the kindness of his friend. To be the friend he used to be.
He glanced at Yuuki, feeling his hunger grow. He needed to find another way to survive.
His time was running out.
