**"The End of Memory"**

In the distant future, Earth was no longer habitable. The atmosphere layer was polluted, the oceans had dried up, and cities had turned to ruins. Humanity was forced to migrate to a planet named "Eden Star," a habitable planet with blue skies, fresh air, and endless resources.

However, Eden Star was not a true paradise. It had no human history, no past, and no memory.

......

In the year 2179, humanity finally mastered the technology of time travel. But this technology was not achieved through massive machines or complex energy fields, but rather a piece of paper.

A piece of paper that could fold time.

It was called "Time Origami," made from an unknown substance from an alien civilization. Scientists could not explain its principles. They only knew that by drawing a scene on the paper and folding it in a specific way, they could open a door to the past or the future.

......

"You are not the key to time, but a reminder that the future is always in our hands."

Then, I tore it into fragments.
