"What is your problem?!"

The high pitched sound of a girl echoed through Class 1-V. It was lunch time and the shrill cry had caused what little people that were left in the classroom to go silent.

Kaiko sighed, resting her chin in her hands as she watched her best friend struggling against a green haired teen's grip on her ribbon.

The green haired boy smirked and gave the white ribbon on a young blonde girl's head a hard tug upwards, making the blonde screech angrily.

"Obviously you Shorty. You dared to ignore me this morning and this is your punishment."

"Don't call me that! I told you already, it's Rin! Rin! Rin!" Rin clawed at the boy's hand, hoping to get him to let go.

The green haired boy laughed at her attempt, "Like I care, now abou-"

"Mikuo! What are you doing? Let go of Rin."

Mikuo scowled, but reluctantly let go of Rin's ribbon and turned to face Rin's twin brother.

"Oh? Back already? I thought you and Miku-nee were having a lunch date on the roof today."

Len blushed at the comment, and quickly slapped a scowl on his face, "It's not a date! And I thought I told you to not bully Rin!" The classroom that had previously been quiet was now slowly coming back to life as the students began conversing amongst themselves again now that the 'usual entertainment' was put a stop to.

After being let go, Rin had quickly stood next to her brother with an angry glare directed towards Mikuo. Mikuo had watched her scramble to Len's side with an annoyed look, "What? Running to your baby brother for protection?" he asked tauntingly.

"Wha-? I'm not running to anyone! I just can't stand being near you!"

Mikuo looked at her coolly with a raised brow, "Oh really?"

Len sighed heavily and ran his hand over his face while Kaiko, who was still sitting at her desk, looked at Mikuo sympathetically.

"Okay you two, that's enough for today." The four directed their attention to a tall red head, who was calmly walking towards Mikuo, slinging his arm around his best friend. "You're gonna scare poor Kaiko."

Kaiko gave her cousin an incredulous look and opened her mouth to say something; but unfortunately, Rin had beaten her to it.

"Akaito-kun! Thank god your here, do something about him please? I just want to have lunch without him picking a fight with me for once." She turned to the red head with pleading eyes, "Pretty please Akaito-kun?"

"Hmm..." Akaito rubbed his chin thoughtfully, "Well...I guess I could...but..."

"I'll lend you my English notes for a week."

"Deal." With a grin, the red head started to drag his best friend away, "You sure know how to be persuasive Rin-chan! Come on Mikuo, Neru is waiting for us."

Rin sighed, and turned to give her twin a hug, "Thanks for coming to the rescue baby brother; I thought he was going to rip my head off."

Len snorted and tried to untangle her arms off him, "Yeah right, he wouldn't do that."

"He was! Kaiko, you saw how hard he was tugging!" she turned to the blue haired girl.

Kaiko nervously shifted in her seat at the sudden attention she was receiving, "Actually, I agree with Len-kun. He wouldn't do anything to really hurt you..."

Rin started at Kaiko, "Why are you always defending him?" she asked suspiciously, "Kaiko...do you like that guy?" Kaiko's eyes widened at the accusation, and shook her head violently, "No! That's not it! It's just..."she bit her lip and gripped the bottom of the sweater of her uniform. She glanced at Len, who took a seat diagonally from Kaiko and gently shook his head 'no'.

"Ah. Well, Rin-chan, I don't like him like that. But I think he bullies you because he...he..." she glanced at Len again, who gave her a pleading look, "he...probably wants to be your friend?"

Rin gave her a confused look, "Kaiko...that doesn't really make sense."

"Yeah Kaiko, you should think of better lame excuses." A deep voice said with a hint of amusement.

Kaiko jumped at the voice, "N-Nero-kun?"

The blond haired boy grinned at Kaiko's uneasy look before turning towards Rin with a flirtatious smile, "Mikuo just likes attention, he's like a little kid. Unfortunately Rin, you are good at overreacting to his messed up ways."

Len snorted and shook his head, "I think that sounds more like you and Neru to me."

Nero laughed and pushed his bangs to the side, "No, no. Though, you're right about one thing, my sister is kind of like that...Well, as they say, 'birds of a feather flock together'...or something."

Rin sat heavily in the seat next to Len with a frown, "I don't care what kind of animal they resemble, he's driving me crazy!" exasperated, she turned to Len with a pleading look, "Can't you ask Miku-sempai to do something about him? He's really getting on my last nerves."

Len looked at her sister oddly, "Me? Why do you want me to ask Miku-sempai?"

"Well, you are dating her aren't you?" Nero asked leaning on Kaiko's desk with one hand, while towering over the girl.

Len's jaw dropped and his face reddened considerably, "Why does everyone think that? We're not d-dating." Nero snickered while Kaiko simply smiled at his defensive words.

"Can we please get back to my problem here?" Rin whined as she gripped at her almost forgotten lunch box.

Kaiko tilted her head slightly to the side, "Well, I don't really think there is much we can say that could help you...but have you tried asking him why he's being so mean to you lately?"

"Lately?" the other three asked at the same time.

Turning towards the blue haired girl, Nero looked at her as if she was an alien, "What do you mean 'lately'? The guy has been being an ass towards Rin since middle school. Don't tell me you never noticed that your best friend has been bullied for so long."

Kaiko flushed at the comment and ducked her head apologetically, "Oh. I...well I..."

Rin smacked Nero's arm lightly, a scowl on her face, "Leave her alone! We haven't been in the same class since our last year of elementary school. She never saw anything."

"Oh yeah..." he rubbed his arm with a faraway look.

"You mean he's been bullying you since middle school? How come you never told me?" Kaiko looked slightly hurt at the information.

Rin scratched head, embarrassed, "I didn't want to worry you..." Kaiko smiled gently, "I see."

Rin sighed and rested her head on her arms, "Besides...I think it only really started in our second year of middle school...I mean, we used to get along so well when we were kids, we were practically best friends. I really don't know what it was that made him change like that."

Len sighed and shook his head while Nero and Kaiko exchanged knowing looks.

'Rin is way too dense.'

Akaito rubbed his arm which throbbed from Mikuo's constant punches, "You don't have to be that mad."

Mikuo glared at him and moved to give him another good punch, Akaito quickly put his hands up in a 'wait a moment!' gesture.

"Hey, come on...I have something good for you that would totally put you back in a good mood."

Mikuo slowly dropped his fist and stuffed his hands in the pockets of his pants.

Akaito, sensing that he was safe for now, grinned.

"So, I had to go see Hiyama-sensei in the teacher's room, and guess what I saw?"

Mikuo nodded for him to hurry it up, "Well...I saw next week's cleaning duty chart, and guess who's paired together." Akaito said in a sing song voice.

Mikuo slowly smiled, "Oh yeah?"

Akaito nodded, "Mhm, Kagamine Rin and Hatsune Mikuo. Starting Monday."

Mikuo laughed, "Well that sure did put me back in a good mood...but..."

"Ow! Why'd you do that for?"

Mikuo shrugged, "For ruining my fun time."
