Chapter 1 - The Knowledge of You

It was nearly 2:40 a.m. as Seto Kaiba entered his large bedroom and slammed the door shut. The rain outside was pounding against the large window overlooking the courtyard along the opposite wall, and he could see a lightning bolt followed by the sound of thunder. Hanging his trenchcoat up in the nearby closet, he walked across the black marble floor and plopped down on the blue covers spread out on his bed. Sitting up, he let out a sigh, turned on the small lamp on the night stand next to the bed, and stared into the covers.

Staying up this late into the night usually wasn't a problem for Seto. He almost always stayed up until three o' clock. But this night was different, as were the past several nights. Tonight he would be granted with a miserable rest only to wake up and be even more miserable. This past week had been absolutely brutal on Seto. Not because of school, or the company, or some dumbass trying to ruin his plans. This hit was personal to Seto...so personal, that he had been only getting two or three hours of sleep a night because of it. He was worried about his younger brother, Mokuba.

For the past week, Mokuba had been staying in a hospital room, an oxygen mask and a few other machines the only things keeping him alive. The doctors had been forcing Seto out every night, telling him that the moment Mokuba's condition improved, they would immediately call him. But every night it was the same; the news was worse rather than better. He was falling behind in work, but he didn't care. Mokuba's life meant everything to him. To lose him...

Seto shook his head, the tears threatening to rise subsiding. He couldn't lose that kid. He wouldn't. The thought of Mokuba lying in bed, so lifeless and cold, chilled Seto to the bone. On a normal day, the kid would come home from school and be the first good thing that happened to Seto all day. He always did his homework before helping his brother out with the company, for he had high hopes of one day owning the multibillion-dollar corporation. "But now that dream may never be fulfilled, along with his other hopes and dreams..." Seto thought bitterly. "Now...now he may not even..." He couldn't even think about the doctor's prognosis without puke threatening to rise in his throat.

"Dammit!" he shouted, leaning back into the bed and closing his eyes. "There has to be something I can do! I'm his big brother, for fuck's sake! I can't just sit here and wait for him to get better! There must be something, anything, I can do to help him out! I have all this money and power at my disposal! He shouldn't be this sick!"

It had all began about two weeks ago. Mokuba had called Seto up from school stating that he felt a little dizzy and wanted to come home. After some negotiation (Seto didn't like it when Mokuba missed school), he finally agreed to take his younger brother home. Driving him back to the mansion, Seto had taken care of him by letting him rest and making sure he ate something. Figuring this was just a small thing, Seto had hopes of his brother's recovery the following day. But the next day, that hope became worry. Mokuba was in an even worse condition, and he decided to call off of school to take care of the kid. He had promised the kid he would protect him and take care of him, and god strike him down should he fail that promise one more time. But it was like this for two more days, Mokuba waking up every day even weaker, before Seto had had enough. He hated the thought of relying on doctors, for he didn't trust them a single bit, but Mokuba's health always came before his own ideals. Taking him to the hospital, Seto explained to the doctors how his condition had deteriorated over the past few days. The doctors promised to take extremely good care of him and to keep an eye on him.

Over the next week, Mokuba's health just continued to drop to the point where he needed a breathing mask and some support machines to even function. The doctors were baffled; they told Seto they had never seen anything like this. The image of Mokuba lying on the bed, the machines' beeping heard in the background, was now engraved in Seto's very being. And it was this image that brought tears into his eyes again.

Wiping them away quickly, he slowly stood up out of bed and walked over to the window. It was still pouring outside, and he leaned against the wall to watch the precipitation. "Mokuba's dying..." he finally thought. "He's dying in a hospital bed, and I'm here in our nice, cozy mansion watching from afar. Those doctors better figure out a way to help him out. I can't afford to lose that kid. He's the only thing that brings me happiness in life. Without him... God, I can't even think about it."

Letting out another sigh, Seto walked back to the bed and laid down, watching the rain pelt the window. Closing his eyes, he urged sleep to come, to force the images of Mokuba dying out of his mind and fill it with a comfortable blackness. He needed sleep; there was no point in denying that fact. The doctors were even starting to worry about his health since he stayed at the hospital so late in the evenings. But he wasn't even slightly worried in his health, not with Mokuba on his deathbed.

"Stop thinking like that!" Seto thought, turning over in bed. "He's not dying!" But Seto was intelligent enough to know better than that. No matter what he told himself, the truth was still there. Mokuba's life was slipping by fast, and there was nothing he could do about it. "Just go to sleep...maybe they'll call tomorrow..." Rolling back over to face the window, he looked outside once more to see the rain letting up slightly. Closing his eyes slowly, he let out a sigh and soon fell into an uneasy sleep.
