Nee Kanda, we'll always be friends right?' A small boy asked the slightly taller male.

"Che. Of course Moyashi-"

"It's Allen BaKanda!"

"-I'm not letting you go anywhere." Kanda declared.

Both boys smiled at each other and promised to never leave each other.

xXx

"Kaaaaanda!" Allen jumped on Kanda's back.

"Hm? Moyashi?" Kanda didn't make a move to remove Allen but put his book down instead.

"I made it into the same high school as you! Isn't that great! We get to be together!"

"Heh, yeah. You're going to hate the classes though, Moyashi."

"It's Allen Ba-Kan-da! A-L-L-E-N! It's only two syllables, or are you to dumb to remember that!?"

"Che.' Kanda got up and started walking with Allen on his back to their own secret hideout. Glad that his Moyashi was going to the same school.

xXx

"Moyashi...what do you mean you're leaving?"

'I'm sorry Yuu but it's not my choice...Master got me into a university across seas along with his job...I have to go with him..." Allen looked down at the ground in shame.

"..."

"I'm leaving tomorrow...stupid master didn't tell me till last minute...Yuu i'm so so sorry." tears dripped down his face, "I really don't want to leave."

Kanda embraced Allen in a tight hug, not wanting to let go of his small Bean.

"It's alright Aren...you'll come back, right?"

"Yeah. I promise Yuu. I'll be back here in no time."

The next day arrived, Allen and Kanda were outside hugging for the last time for who knows how long.

"Oi! Hurry it up you two! I'm not missing the damn plane! It's bad enough that I already gotta drive to the airport!" a angry redhead called from the car.

"Well then Yuu...I'll be off."

"I'll see you later Moyashi."

"Sure thing. BaKanda."

Both boys smiled brightly at each other, making another promise. 'We will see each other again.'

As the car drove away from the now empty house, Kanda started crying silent tears. And a old promise raced through the lone boys mind. Only increasing the tears down his face.

"I thought we promised to never leave each other, Aren."
