Kagamine Rin was an average girl with average goals, the only problem was... she was rich. Her parents often went on long trips overseas and took her with them, but she was growing up. Rin was now fourteen, which to her father meant she had enough knowledge of the world to live on her own, but her mother was apprehensive. They quarreled for days, trying to decide what was best for the young girl and in the end decided to send her off to boarding school. This is the story of that young girl's first and only love, the one that she would spend forever with.

~Hearts Racing~

"Rin, can you carry these handouts to Kamui-Sensei?" A voice called from the front of the class.

"Coming!" Replied the young girl from the back of the classroom.

Rin grabbed the large stack of handouts and proceeded down the hallway to the west wing of Crypton Academy. Carrying so many handouts proved to be a difficult task, the papers would take a dive to the ground and Rin would have to go back and pick them up. Nearing the west wing she had the papers stacked so high she could barely even notice that she had actually reached her destination, as they were piled up to her face.

"Here, let me take half and you can take the other" called a voice from behind the wall of handouts. Shortly after, half of the weight of the handouts was lifted, putting Rin at ease. The girl who had so willingly helped her proved to be a true beauty too.

"Do you mind me asking your name?" She asked in a sweet voice, one that could have only belonged to someone as gorgeous as her.

"It's Rin... Kagamine Rin." Rin was at a loss for words, the girl's beauty was too much for her to even comprehend. 'Why do I feel like my heart's beating faster?'

"Well Rin, It's a pleasure to meet you! My name is Hatsune Miku, and I'm looking forward to being your Onee-Sama" The girl, Miku, Flashed Rin a smile which made her almost melt right then and there.

"O-Onee-Sama?" Rin questioned, wondering why the elder girl would want her to call her sister.

"Yes! The girl that you most admire and look up to, I want to be your Onee-Sama... I admit, the urge to protect you is growing great" Miku had an air of seriousness in her voice, but all the while kept that sweet smile and cute composure.

"O-Okay then... so does that mean that I would be your little sister?" Asked the blonde, still puzzled as to how a situation like that would work.

"Only if you wanted to be, of course."

Rin had been here for a month and had heard lots of talk about Miku, all the girls in the academy seemed to be infatuated with her. They described her beauty as unrivaled, she would look good with just about any girl in the academy. The problem was that this mysterious girl of whom Rin had just seen for the first time was supposedly stubborn. She wouldn't take anyone in that didn't meet her standards, which apparently were very high, as she had come from a rich family, just like Rin. That seemed to be the case throughout most of the academy, parents were too busy with their various companies to take care of their own children so they sent them off to boarding school, with Crypton Academy being number one in the nation.

"I-I guess we could become like that..." Rin managed to stammer out, trying to compose herself.

"hehe, wonderful! You're just so irresistibly cute, I'm surprised none of the other upperclassmen have taken you in by now." Said the teal haired upperclassman.

They had reached the end of the west wing and ended up doubling back, as they had passed their destination some time ago, but it didn't matter to Rin, with this girl she felt like she could just let go and be herself, after all, she had just shown her a great amount of kindness taking her under her wing like that.

"I believe we're at your destination, Rin-chan" Said her newly acclaimed Onee-Sama.

"Oh, you're right, you'll have to excuse me for spacing out like that" Rin sighed, feeling like a complete moron.

"It's perfectly fine, we all space out sometimes" Miku said, trying to cheer the younger girl up after making her mistake.

"Thank you for helping me, O-Onee-Sama" Rin stuttered when saying Onee-Sama, not used to calling anybody by the more than friendly nickname.

"It's quite alright, I'm sure we'll be seeing more of each other soon, in fact..." Miku sat the papers down on Kamui-Sensei's desk, Rin following suit, "How about you and I have a picnic? today after mealtime, I'm really interested in getting to know you better, you're such a sweet girl, Rin" Rin's heart skipped a beat when Miku dropped the honorifics on her name, gasping like an excited schoolgirl, but that's what she is, isn't it?

Miku noticed the change in environment and quickly adapted, knowing just the moves to pull to make her newly acclaimed "Onee-Chan" become more than just so.

"Judgin by your reaction I'm guessing you'll be there, meet me under the cherry blossom tree, and don't eat, I'll prepare something lovely for you." Miku leaned closer to her prey, whispering in the younger girl's ear "See you then" then giving her a light kiss on the cheek before disappearing down the hallway without another word.
