aibou-doodle: Seto Kaiba will share my caffeine-withdrawal pains. Haha! Although, day one and I'm feeling good!!

Disclaimer: I don't own Yu-Gi-Oh! And Seto Kaiba is extremely thankful for that fact.

Warnings: Mild swearing. And lack of caffeine.

Day One

Seto awoke the next morning at 6:30am. He went through his usual morning routine of washing and getting dressed before he walked down to the kitchen at 6:52am. Mokuba was already sitting at the counter eating some sugar-coated cereal and reading a gaming magazine.

"Good morning, Seto!" Mokuba said. Seto only grunted in response and moved over to the cabinets and began taking out a mug. He opened another drawer and took down a pack of his favourite blend of coffee.

"Ahem." Mokuba was scowling at his older brother, with his hands planted on his hips. "Seto, you can't drink coffee anymore, remember? We made that bet last night!"

Seto blinked and looked down at the coffee. He growled and shoved the packet back in to the drawer. "Damn," he muttered. "What do I drink instead?"

"Water."

He felt his eyebrow twitch. "Water?" he repeated.

Mokuba nodded. "Yes! It's healthier for you. How much water can you say you drink in a day?" Silence. "Exactly. No wonder you get headaches -- coffee dehydrates your body. So from now on you will drink water. Understood?"

"Ugh, understood," Seto grumbled. He ruffled Mokuba's hair before he left the kitchen. "I'm going to work. Be good in school."

"I will!" Mokuba waited until he heard the front door open and close before he moved from his spot. The younger teen bolted up the stairs and went to his bedroom, where he turned on the computer and opened up his email. "Now, to make sure Seto doesn't cheat." He cackled evilly.

"Good morning, Mr Kaiba!" An overly cheery voice greeted him as he walked towards his office, and Seto held his firm belief that anyone who sounded that happy in the morning did not deserve a response from him.

Corry clucked her tongue in disapproval but carried on. "There are four more contracts waiting to be signed so I put them on your desk. The manager of Human Resources called and said that they need more employees in the office downstairs if you want the new model of the Duel Disk out by summer, and Mr Pegasus called -- he wants to know if you would partner up with him to create a new trading-card game."

Seto sighed as he opened his office door. "I will sign the contracts and send them out to you before lunch, email Frank and tell him that I'll give him as many employees as he needs if he can get the Duel Disk finished before summer, and tell Pegasus that I'm not interested in another card game and that if he steps foot in Kaiba Corp I will get a restraining order on his ass." He stepped in to his office. He was about to close the door when he jerked it open again. "Hey, Corry!" he whispered.

She raised an eyebrow but whispered back, "Yes, Mr Kaiba?"

"What are the chances of you getting me a coffee now?"

"None," she said with a snort of laughter. "I got an email from your brother a few minutes ago. He's asked me to make sure you don't cheat with your Lent."

Seto growled and slammed his office door shut.

That was just fine. He didn't need the coffee anyway.

Definitely not.

"Ya made him do what?!"

Yugi looked up from his desk and saw Joey walk in to the room with his mobile held against his ear. He was laughing at something the person had said and there were almost tears running down his face. "How do you know he'll follow through with it?" Pause. Joey grinned, "You're pure evil. Let me know when he's coming back t' school -- I wanna tease him about! 'Kay, bye."

"Who was that?" Yugi questioned as soon as Joey had put the phone in his pocket. The blond sat down at his desk, still chuckling before he replied.

"That was Mokuba," he explained, the grin still on his face. "He told me that he has a bet going on wit' Kaiba."

"What did they bet?"

"Mokuba bet that Kaiba couldn't last forty days without coffee."

Yugi blinked and then burst in to a fit of giggles.

Tap tap tap tap tap. Reach for coffee mug. Clasp thin air. Growl.

Tap tap tap.

Bang head against desk.

"Welcome home, big brother! How was -- are you okay?"

Seto glared dully at Mokuba as he collapsed face-down on the couch. He sighed miserably and his arm dangled off the edge. "Coffee," he muttered.

Mokuba's eyes lit up with amusement. He stifled a giggled behind his hand and asked, "Lent not going so well?" There was no answer. "You know, you can just admit that you can't do it--"

"Never said I couldn't," Seto interrupted. "Oh, and I'm hiding your video games."

"Eh? Why?"

"Because you got my secretary to gang up against me."

"You asked her for a coffee!"

"Details, details."

A/N: Yeah, it was short. I will update next Wednesday, and it should be longer since I'll be cramming in about a week of caffeine-withdrawal drabbles in to the one update! Stay tuned.
