Ever since I could remember, I had been having dreams - no, they were more like nightmares. Over and over again, repeating every night that I had every minor detail memorised. I couldn't remember a time where I didn't see it.

It always started with a scream. It was high-pitched; female-like. It sounded familiar, but I could never pin-point where I had heard it before.

Then came the excruciating sound of bones breaking. It was unbearable, I didn't want to hear it ever again. However, it was futile. The crushing of the bones wasn't what got to me, it was the face - the cries that it made. I couldn't bare to look at it anymore.

Although, at the same time, I didn't want to forget.

There was always this ray of light that shone in the depths of my own despair. The hope that I gained just from seeing it helped me to recover. But then it disappeared as fast as it had appeared.

And the man-eating monsters suddenly reappeared again.

I woke up screaming in the middle of the night. Nothing ever happened after that - I couldn't remember what had happened after that. It was always just a blur, but I could remember vividly a pair of piercing grey eyes staring straight into my very soul.

The day I turned fifteen was also the day the nightmares eventually stopped. I thought nothing of it as first, but then I started to wonder - started to wonder why. I couldn't help myself, I was curious, I always had been.

I shouldn't have been curious, and I most certainly shouldn't have not listened to the man's words.

"Don't forget."

I turned around, facing a man who stood at around five feet tall, "Don't forget what?"

He didn't respond however. He just pivoted and walked in the other direction. I wanted to call out to him - wanted to tell him to wait. I wanted to know.

What did he mean by those words?

The next day, I bumped into him again, and again the next day after that. This routine continued on for another month, but it was always the same no matter where we met.

"Don't forget."

"Don't forget."

"Don't forget."

"Don't forget."

Do not forget, Eren.

It was different this time. The way he said it was different. It was the same day I decided to confront him. I was tired of it - tired of not knowing.

"What am I supposed to not forget?!" I yelled at the man, "Why do you keep telling me not to forget?!" I paused, "How do you know my name?"

He stayed silent for a moment, and I thought he was just going to leave like he did the first time. But, to my surprise, he didn't.

"Don't forget about me." He said it with a voice that was just so sorrowful, so full of sadness. I didn't like the way it sounded.

Why did he sound so sad?

I felt the urge to hug him but I didn't know why. So we just stood there, staring at each other, waiting for the other to speak. I was the one to break the silence.

"I won't."

Those two words held so much promise in them that it scared me. It was an unspoken promise that I didn't want to break, not now, not ever.

It felt so familiar, this scene. It was almost as if it had had happened before a long time ago. He felt so familiar.

Where had I seen him before?

I thought and thought, but it never came to me. I was frustrated with myself that I couldn't remember who he was. But then I realised.

"I'm sorry," I whispered to him, "This was what you meant, wasn't it?"

I received no answer. I saw the sadness in his eyes - though, it was only brief as he turned and walked away just like he did a month before, and just like last time, I couldn't stop him.

That night, the nightmares came back. The same one with all the screams, the crushed bones and the man-eating monsters. I couldn't take it. Night after night, they became more real - more vivid - I could practically feel it.

It felt so real.

I didn't see him anymore after that. It was almost as if he had given up on trying to make me not forget. But I did, and I could never reverse time.

I felt guilty for that fact. I couldn't remember who he was, and I spent every second, minute and hour of the day trying to remember what I had forgotten.

His words ran through my head like a broken record. "Don't forget," He had always said, "Don't forget about me."

Then it clicked, and instead of spending my days thinking, I spent them locked up in my room, crying. I couldn't reverse time. And I hated myself for that. I would do anything just to spend more time with that man.

"Levi..." I bawled, "I wish you were here..." That was his name - Levi. I couldn't believe that I had forgotten who he was and what he meant to me, "I remember you, my love. My beautiful, beautiful soldier, I remember you. At last."
