Hello, Me

Disclaimer: I do not own Attack on Titan or any of its characters.

Universe is quite mysterious.

It is vast, unlimited amount of space filled with stars, galaxies, life, and many other unknown things. Many theories are made about it, quite a lot of them still waiting to be proven.

However, what if, the universe, our universe, is only a fraction of even bigger, even vaster of something… more?

And, what if, in the vast something, there is other, countless numbers of universes, all similar but not quite the same, all related and unrelated?

What if, in the other universes, there is another set of me, you, and everyone else?

This is called a parallel universe.

Let's say that this is all true. Let's say that, just like a set of parallel lines, these universes, with other versions of you, me, and everyone else just existed, never touching each other, never influencing each other.

That is, until fate grew bored and decided to let one lucky, or unlucky, human being through to another world.

The fate chose its victim.

The fateful day, in fact, did not seem at all fateful. There was no lightning striking out of a bare sky, no dark clouds threatening to spill, no wolves howling mysteriously.

No, none of that.

It was a sunny, blissful day. The birds were chirping, and the sky was stretching endlessly, to the horizon, no cloud to be seen. The trees shook their leaves in harmony, and grass sparkled like jams, light bouncing off their recently watered blades.

However, on this perfect day, in a certain old castle, a certain boy with a certain name of Eren Yeager with gold eyes full of lust was unable to enjoy this weather, do to his chores. Cleaning duties, to be exact. Ugh, he thought. He hated his chores. It wasn't that he didn't like being clean. It was that he had to clean the whole castle by himself. His captain, Levi Heichou, was a clean-freak and insisted the castle to be cleaned once a week. It rotated around the team members, and he had the job this week. Usually, Petra or Mikasa would help him, but today, they were too busy with their own chores to help out. He sighed and looked out to the window, a duster in hand. He wished that today wasn't such a perfect day. He longed to be outside, training. Or if he had the yard duty! Anything about outside sounded wonderful just now.

"Are you slacking off, Yeager?" A cool, unemotional voice said behind him. The Eren hurriedly turned around and saluted, his duster still gripped in his right hand.

"L-Levi Heichou! No, sir, I wasn't slacking off, sir…." He mumbled, guilty.

"Oh, really? Anyway, redo downstairs. You call that clean?"

"Yes, sir." Eren sighed, once again, dismayed at the work ahead of him. As he walked downstairs, in that exact moment, was the moment fate decided to interfere. The fate stretched, pulled, and warped the space, just enough to let the golden-eyed boy to another world. Nothing dramatic.

The boy stopped and looked around. For a moment, there was certain…wrongness in the air. Now it was gone. Eren shrugged and kept walking. Lost in thought, he did not see another person, who was exactly as tall as himself, and bumped against the person, dropping his cleaning supplies.

"Hey, watch where you're going!" The person snapped, bending to pick up his own items. Eren was going to retort back, and froze. The voice sounded vaguely familiar. Almost afraid, he slowly looked up. Warm, tanned skin. Leather cord at the neck. Firm, defiant lips. A mess of brown curls.

He found himself staring at himself.
