He knew making excuses was a sign of weakness, but the boy figured that maybe just for that particular case he's allowed to make excuses. He was sure he had beaten the Dragon Woman, and he was sure the gigantic door that led to his twin was already opened somehow.

He was sure he had seen her back.

He was sure of all of it. He had fought, and won. He had found his princess, and just one step away from embracing her. Just one step away from hearing her angelic voice, just one more step to touch her pale skin, just one more step…

And yet…

"Mata meguru…"

'It repeats…'

Len closed the book he was holding and placed it on its original place in the library. The bookworm was ultimately disappointed by the story he had just read. The maker of the story was one of his favorite, specialized in making stories from old times, and most of the endings ended in tears and death, but even though Len hated that kind of ending, the stories touched him. He could feel the feelings of the characters in the stories, and that made him always waited on the author's next works.

But, the book he had just read was a defect; a failure among literature. The story was titled 'Synchronicity', a story that took place in ancient time when the world's happiness is guarded by a singer that put dragon to sleep. As long as the singer kept on singing, the dragon shall remain asleep, and the world's safety was guaranteed. The plot was good, the art was perfect, and yet, the story had no ending.

The story was cancelled, and thus the ending was never revealed. The library held one copy of the finished work and at the end it's explained by who's probably the author's assistant that the story would not be continued.

"It'd be good if the songstress can be freed…" he said nonchalantly as he walked away.

It was only a wish from a reader.

A wish that happened to be the exact same wish the boy in the story made. The wish that was screamed with soundless voice as he reached out to his sister, the wish that could not be granted even if history repeat itself as the book read again and again.

'You're right. It'd be good if that's the case, isn't it?'

The blond haired boy stopped on his track. When he came to the library he was sure that no one was there, and he hadn't heard any voice indicating the door had been opened. And yet, a deep childish voice could be heard in the supposedly empty library.

'Len Kagamine, do you truly wish that to happen?'

His vision was getting dark, and he realized it was because something shone from his back. Len turned, and found the book he just read to float mid-air, the pages seemed to turn as it floats until it stopped at the page where the main character picked up a necklace from the ground.

"The beginning of the story… Don't tell me!"

Like in the failed literature, this story started when the main character picked up his sister's pendant from the ground, not realizing the grin of a masked figure hiding in the shadows not far behind him.

I know I've said this before, but I lost my laptop and my datas. My muse ran away with it. So, I'll write this in return, dedicated to all unfinished story. Based on the most famous unfinished story on Vocaloid fandom, Synchronicity.
