Disclaimer: I do not own Vampire Knight or any of the characters because that pleasure belongs to Matsuri Hino.

Author's Note: I have begun to revise this story because the beginning chapters were out of character and I felt that the plot needed more direction. The main idea of the story remains the same, but I will be making slight changes here and there in order to improve the flow of the story. Thanks for reading and I hope you enjoy it!

…Chapter One…

"So to find x, you have to multiply by this and then," Yuki trailed off and furrowed her brow as she attacked her last assignment of the evening. Despite an easy night of patrolling and only one small stampede of fan girls, she was fast approaching the early hours rather than late hours. Yuki rubbed her hand over her eyes once again before determinedly scribbling answers beside her equations. It was in the midst of this scribbling that Zero found her, lower lip caught firmly between her teeth and nose almost touching the page as she drooped over her work.

Leaning against the door frame to the kitchen, Zero took in the small dark haired girl propped up at the kitchen table. Her efforts to stay awake were failing and he watched as her large brown eyes came dangerously close to closing for the rest of the night.

"Yuki," Zero said as he nudged her elbow off of her homework page. "Yuki, you're doing your homework wrong again."

"Gah! Zero! Oh no!" Yuki started awake. She looked down at the equations with dismay and back up at the lilac eyes gazing down at her.

"Look, it's too late for me to help you now. We'll do it in the morning," Zero said, shaking his head at some of the answers she had written down.

"Okay, good night Zero," Yuki smiled sleepily as she wandered toward the bathroom to brush her teeth.

"Good night Yuki," Zero said as he headed to his bedroom. Yuki waved her hand as she closed the bathroom door.

Once in his room, Zero almost laughed aloud remembering that his adoptive sister had managed to get four as the answer to an equation asking for the square root of one. He caught a glimpse of himself in the mirror behind his door and half-heartedly ran his fingers through his silvery blonde hair before climbing into bed with a glare at his reflection. Zero was beginning to feel a familiar tightening in his throat but he stubbornly ignored it. He needed sleep if he was going to make it through a morning math session with Yuki tomorrow. He could deal with his other worries tomorrow night. He could wait. He had to wait.

…

There was a strange buzzing sound coming from Yuki's favorite stuffed animal. Yuki blinked down at the cuddly item with confusion, it had never made noises when she squeezed it before. Then she realized that the buzzing sound was coming from the table beside her bed.

"Oh!" Yuki tumbled out of bed and grabbed her robe as she dashed toward the bathroom. Her old yellow robe was only half on as she stumbled into the bathroom, struggling to reach her sleeve. She was met by a stern pair of eyes in the mirror as a fully dressed Zero stood brushing his teeth.

"Good morning!" Yuki smiled as she reached for the pink toothbrush dotted with tiny yellow flowers. Zero merely grunted in response and rinsed his mouth.

"Don't forget that we have to go over your math again," he said as he left the bathroom.

"I won't," Yuki answered, her smile drooping slightly.

…

"Okay Zero! I'm ready to finish my math now," Yuki announced as she took a bite of toast and dropped into a chair at the table.

"Okay, it looks like you made a mistake here and here. This is what you have to do," Zero leaned over Yuki's shoulder to point out her mistakes and froze. He was too close; he could smell the peachy scent of her shampoo. Zero clamped his mouth shut and all but ran around the table to sit across from Yuki instead. Letting a controlled breath out through his teeth, Zero continued to talk Yuki through her homework from a safer distance.

…Chapter End…

Author's Note: I know it was short, and I apologize for that. Once we get into the plot more and I have more time to write, the chapters will get longer! Please leave me a review and tell me what you thought!
