Hi guys! :D This is just a random brothery fluff story of the Kaiba brothers. Seto is a little ooc here... I hope you enjoy anyways XD

Mokuba woke up groggily, it was 2am, but he was struggling to sleep, because it was one of those uncomfortable, hot, stuffy nights where it was difficult to sleep. Plus, he was worried about his brother, Seto. He'd been working in his office all day and he was still there when Mokuba went to bed and he didn't look even close to finishing whatever he was doing. In fact, he had been working like crazy the past few days, only getting a couple of hours sleep each day. Sometimes he got no sleep at all, making him more stressed and irritable than normal, which wasn't a pretty sight.

Mokuba crept towards Seto's office and peered inside. He couldn't see his brother. Had he actually gone to bed? But, then why was his computer still on? Mokuba tiptoed over to the side of the desk, to find Seto resting his head on his arms, with his eyes shut.

"Seto...?" Mokuba said, taking a small step closer.

At the sound of his voice, Seto opened his eyes and rose his head, slowly. It took him a few moments to focus.

"Mokuba? What are you doing here? You should be in bed, it's late." Seto said.

"Sorry, I was just checking on you, seeing as YOU should be in bed, as well." Mokuba replied.

"Don't tell me what to do." Seto growled, speaking in his usual stubborn tone.

"But Seto! You've working so hard for the past days. You've bearly eaten and slept for ages!" Mokuba argued.

"Go back to bed Mokuba."

"Not until you do."

Seto paused for a few moments, then he raised his hands in defeat.

"Fine. You win, Mokuba. Although, I sometimes wonder where you get your stubbornness from..."

The two brothers headed to the door, when Seto stopped suddenly.

"Before I go to bed, I need to put away my duel disk and deck." He said

"Do you HAVE too?" Mokuba whined.

"Yes."

"But why?"

"Because I say so."

Mokuba looked up at his brother with large eyes. Seto let out a small sigh, but his expression softened.

"Look... it'll only take a few minutes. I promise, I'll go to bed straight after." He said, his voice surprisingly gentle, for someone so cold-hearted.

"Fine..." Mokuba sighed, watching his brother walk downstairs. He sat at the top step.

10 minutes passed, what was Seto doing? Mokuba wandered downstairs. He ended up finding Seto asleep on the sofa.

Mokuba prodded the side of his face, "Big brother?"

Other then slight grunt, he got no reply. Seto was completely sound asleep. Mokuba had little to no chance of waking him. But at least he was sleeping. Mokuba, starting to feel sleepy himself, quickly grabbed a cushion from an armchair and carefully lifted Seto's head and tucked the cushion underneath him.

As Mokuba headed back upstairs, he paused at the doorway.

"G'night, Big bro."
