Author's note : This is what Rin was doing when Len went to meet with Miku. :D This is Kaito and Rin in a pairng, don't like, go away. =3= Cause I didn't know who else to pair up with Rin. I still don't own Vocaloids, though... THE WORLD IS CRUEL!

After Len's phone had loudly rung, Rin burst out of bed. Today was their birthday! Wonderful.

"I wonder who's calling Len," Rin muttered to herself as she stood there, unnoticed by her twin brother, in her pyjamas. Len seemed pissed off at being woken up at 8am by someone so inconsiderate to call that early, but he brightened up after somebody's muffled words came through the receiver. It was definitely Miku.

"Hi Miku!" Len said quickly and happily. More muffled words came thorugh the phone.

Rin had to say, it was really FUN to see Len so happy to hear Miku's voice, then suddenly look dejected. Probably, he was hoping she was finally going to ask him on a date. Well, Len couldn't blame the teal-haired girl for calling early. She was always a morning person anyway. Rin understood very clearly (like all the OTHER Vocaloids did) that her twin brother really did love Miku. Which was why whenever Miku went out with someone, Rin would always ask that boy to either not be sweet, kind, or adorable. Some of the more stubborn guys would refuse, until the blonde girl brought up the subject of her roadroller, of course.

So it was no surprise that every date Miku went on with any boy at all was a complete failure. Heh. But sometimes, Rin did wonder how Miku could completely forget that Len was a living, sweet, kind and adorable boy that she could actually go out with.

Having all this said, Rin was already done changing out of her pyjamas while she was in the bathroom. She had gotten ready for the day, and had something special planned for the day. But first, she needed breakfast.

"Um...Kay... Anything else you wanted to tell me?" her twin continued on, and after a few more muffled words, he was hung up on. Rin could almost feel his sadness radiating from him.

"That was Miku again, huh?" she asked her twin brother. He gave only a nod as a response before plopping back onto his yellow bed and throwing his equally yellow blanket over his body.

Rin had been leaning against the doorway, but she was now standing up by herself, eyes narrowed at her brother, who was being lazy at the moment. She was hungry, and bored, and hungry.

"NO! Get up, Len, go make breakfast!" she demanded.

Len mumbled something unintelligible from under his blanket. Sometimes, he can be so... so... LAZYASS! Rin thought. Suddenly smirking, she stated purposely, "I guess... I'll cook breakfast again... I just hope the house doesn't catch on fire like last time..."

Yup, the last time she had tried to cook something, she had thrown the food with the packaging still on into a cooking pan, then poured oil all over it, spilling some onto the cooking fire. The fire jumped a bit, and Rin noticed that her jacket's long sleeves had caught on fire. She quickly threw the burning clothing off, and ran around the house screaming Len's name.

Rin sighed. Those were good times. At least, only because they both survived.

Len jolted out of his bed and ran into the bathroom, ran out 5 seconds later all dressed and washed up, and Rin swore he was floating down the stairs at the speed of a cheetah or something.

By the time she got down, he had already made 6 pancakes, and was now flipping them. He almost looked like a juggler.

"Rin, go prepare the table!" Len called from the kitchen. It had taken a lot of training, but eventually he had managed to teach Rin how to set a table without sending anyone to the hospital.

Rin gently set down two plates big enough for pancakes, a spoon and a fork beside each plate , and two glasses for orane juice onto the table. Len filled them up almost right after she set them down, and then threw the pancakes -3 on each plate- down. Since she had something planned for the day, Rin ate rather quickly and ran out the door after saying 'Goodbye'. She also noticed that Len was slow at eating stuff.

While Len stayed home, Rin ran off toward the ice-cream parlour, where she was sure Kaito was. It took a full half-hour to get there, but it WAS worth the run. Then again, she COULD have used her roadroller to get to her crush.

Yes, of all the guys the cupid could shoot with its arrow, it chose Kaito for Rin.

"Heeeeey Kaito!" Rin called as she waved wildly, coming into Kaito's view. The blue haired man, of course, was wearing a coat and scarf and holding an ice-cream. At this time of the year, Kaito didn't seem crazy to be wearing what he was.

Kaito spun his head around, and saw the cute blonde girl running toward him, her white rabbit-ear bow bouncing. "Oh, hey Rin!" Kaito answered her call. "Want some ice-cream?"

Rin declined. "Notice anything about me?" she asked. While she was in the bathroom that day, she had applied some lip gloss onto herself, just for Kaito, hoping he would notice it and stop thinking of her as a tomboy.

Kaito looked her up and down, before deciding to answer with a, "You have a flat chest."

That answer earned him a slap. "WHO THE HELL TOLD YOU TO LOOK THERE?" Rin's eyes would have been red if it were possible. They were practicly bulging out of their sockets.

"S-sorry! Sorry!" Kaito apologised as he held his sore cheek. He was smiling in amusement, though, at her reaction. "So, you want an ice-cream? I love it much more than anything in the world! Well, maybe except Miku."

Rin's glare faltered at the name 'Miku'. She looked down at the pavement. What a love triangle...

"Hey, you okay? You have tears dripping onto the ground, Rin," Kaito bent down slightly to meet her eyes with his own. Eyeing his face, she continued to cry, not caring if he was looking anymore.

"So you... love Miku... and ice-cream... more than," she sobbed sharply here, saying the next word with a cracked voice, "me...?" Tears poured from her eyes, the 2 streams joining together between her chin and throat.

Something about seeing the younger Vocaloid cry made him blush and think one word : cute.

Wait... I shouldn't be feeling like this... I love Miku... Kaito thought.

Flashback

On the day of Kaito's admittance of his crush on Miku, she smiled, and said, "Kaito, I love you too. But as a big brother, so I'm sorry."

Of course his heart was cracked a bit, but it didn't matter. He wouldn't give up.

Flashback Ends

Maybe... maybe he just loved Miku as a big brother would love his younger sister. Just like she loved him as an older brother. Rin started to walk away, cursing that today was her birthday, when Kaito grabbed her hand.

"Rin, wait! I love you!" Kaito grinned like an idiot proudly at his admittation.

Rin, of course, was confused. "I thought you said you loved Miku."

"Eh... I realised I loved her as a sister," was the reply from the ice-cream loving idiot.

Rin, of course happy with this fact, started giggling at Kaito. "Kaito, you idiot."

"Huh? What did I do?" Kaito asked, afraid that his death would be caused by a roadroller.

Rin kissed his cheek before running off, yelling behind her, "You stole my heart!"

Kaito held his cheek, ignoring his precious ice-cream that had melted during the whole event. (This shows he loves Rin more than ice-cream)

Meanwhile, Rin was excited about telling Len of her day. She started skipping, knowing that Len wouldn't stay home all day by himself. She passed by the park that was near their house, and started calling for Len. By chance, she happened to see Len and Miku about to kiss, with a mistletoe above them, then the two suddenly darting away from each other after hearing Rin's voice.

"Was I...interrupting something...?" Rin asked regretfully as the two slowly and embarrassedly nodded. Rin started backing away, intending to give them privacy. "I'll just... leave now," She winked at the two, to say 'Congrats to you two'.

Rin backed into Kaito, who had followed her all the way to the park. He was panting, but what else could you expect from a guy who got his energy from ice-cream?

"Kaito! What are you doing here?" Rin asked, aiming to distract him away from her brother and his should-be-girlfriend.

Kaito had no intention of going any further than Rin, though. "I just forgot to say something back at the ice-cream place."

"Oh. What?"

"Happy Birthday, Rin!"
