It was a sunny morning and all the kid at the orphanage was outside playing. Mokuba, unlike Seto, was inside sleeping or, more exact, he just woke up.

The raven-haired child yawned cutely then looked around, Seto wasn't there. Mokuba sighed and looked at the clock, "It's only 10:00…I could sleep some more or…" Mokuba stopped talking when he heard some talking.

The 5 year old opened his bedroom door into a slit and started to eavesdrop.

"You know, it's really sad. I can't believe Mappy left. He was the best friend anyone had." said a boy with blue hair. Another boy with green hair nodded, "And what's worse is that him and Viker were like brothers. Viker's been so upset, he's crying you know, emotionless Viker's crying."

The blue haired boy looked down, "It always happens here you know; it's not that good to get close to anyone. You never know how attached you get before they leave and forget you…" The boys stayed silent.

Mokuba stopped listening, he closed the door completely and fell down slowly with his back against the door, 'I can't Mappy left…oh god, Viker' Mokuba's eyes widened, Viker was in an even worse position. He just lost his closest family.

Mokuba sighed; he looked outside of his window for a few seconds then he did the normal morning process.

Seto laughed, "Syde, that can't happen, it's not possible, not logical."

A boy Seto's size but he had glasses and short messy hair, "Seto, it's true. Just cause you're like the smartest person here doesn't mean—"

"Hmm em." A raven-haired child cleared his throat, "Syde, can I take Niisama away from you for a moment?" Syde nodded, he left to go talk with some girl.

Seto smiled, "Good morning Mokie." The brunette rubbed Mokuba's head which had no effect what so ever.

Mokuba put his hands on his hips, "Promise me Niisama; promise me you will never leave me, kay?"

Seto blinked, "Mokuba, you do know I already made that promise when Jero left, right?"

The 5-year-old sighed, "Yes but you just promised. You can easily break a promise without breaking the law if you didn't pinky promise it."

Seto bit his lip; he opened his mouth then closed it again. Seto scratched his head, "I'm lost Mokuba...what are you talking about? Law, there's a law about promising things?"

Mokuba frowned, "Yeah, you're super smart, shouldn't you know that already?" Mokuba shook his head, "That's not the point now Niisama." He stuck out his pinky, "Pinky promise that you'll never leave me and then I'll know you mean it."

The 10 year old brunette brushed hair off his face, he looked at Mokuba again who still had his pinky out and was pouting.

Seto smiled, he wrapped his pinky around Mokuba's and said, "I pinky promise that I'll never leave you."

Mokuba grinned; "Yay!" the child hugged his older brother.

Seto chuckled, "So Mokie, can you tell me more about these laws since you seem to know so much about them."

Mokuba nodded and began explaining.
