Okay, since everyone seems to be confused in the later chapters, I'm gonna leave a note here. This story contains heavy Levi/OC, meaning there's a lot of interaction between them (not sexually), but I assure you: this is an EreRi story. The endgame is EreRi. The Levi/OC relationship is there for the plot. So if you don't want to see Levi/OC, then you're not in the right story.

I repeat; this is an EreRi story with heavy loads of Levi/OC. If you can't handle that, it's fine. I don't want to make any of you uncomfortable so I left a note here.

If that's okay with you, please proceed.

10 years ago

A little raven haired boy sat alone in one of the swings using both of his small feet to will the swing to move. Among the swarm of children in the park, running around, laughing and talking to each other, enjoying themselves as they bask under the sun, this little raven is almost unnoticeable. Little hands wrapped around the metal chains which holds the swing from the metal above, he ignored the little pinch of loneliness pooling in his gut.

He would never admit it, though. The stoic, impassive look on his face wouldn't give any of that thought away, and he already experienced other children his age running away from him because of it. It made him frown in disdain before he looked down, noticing how his feet couldn't reach the ground, making him unable to make the swing move. The inability to move made the crease in between his eyebrows deepen, silently blaming his height for it.

He sure is a little short for children his age, but his maturity was surprising. He isn't a snot covered child who is always drenching in sweat and dirt like the others. Instead, he's always in a clean and pristine condition, not letting himself be covered in any dirt. He talks in a way that's a little advanced for his age, making him a bit intimidating.

That doesn't change the fact that he's still a child, though, and there are times when he wanted to play.

Like today.

He huffed and crossed his arms, irritated by his current situation, not aware of the twins who are silently giggling behind him.

The sudden jerk of the swing almost made him fall to the ground, save for a pair of arms that helped him balance himself. As he recovered from the sudden movement, he snapped his head back to glare at whoever pushed his swing. What he saw is something he didn't expect.

Two faces of the same look stands behind him. They have the same look except for the color of their eyes- one with turquoise and the other with amber.

He's amazed with what he saw being the child he was but his face denied access over his thoughts. He looked at them with a blank face as they returned it with a bright, wide grin.

"Hi! My name's Eren and this is Rein! We're twins!" The child with the turquoise eyes greeted him in a very energetic tone. The other with the amber eyes smiled and waved at him. He was surprised by how friendly the twins are, not being repelled by his looks unlike the majority of the kids their age.

"Yeah, it's pretty obvious," he answered in an uninterested manner as he continued to look at them. "Why did you pushed the swing? What if I fell from it?"

Both of the twins gave him an apologetic look. "Sorry, I told Eren to just approach you and talk to you but he insisted that it would be much better if we'll surprise you," the Rein kid said as he gave his twin a glare.

"Sorry, we just want to talk to you. I don't want our first meeting to be boring." The Eren kid stuck his tongue out at his twin, acting childishly.

'Boring? What? Does making me fall to the ground can make things interesting?'

He rolled his eyes. He thought that they're not one of those insufferable brats but based on how they're acting, especially the Eren kid, looks like he's wrong.

"So what are you doing?" Rein took the swing at his right while Eren took the one at his left. Great, now he's forced to sit in between two weird kids having the same faces.

"Sitting and breathing in case you cannot see," he answered in a way full of sarcasm which made the twins huffed at the same, very exact time like they're in sync. They looked at each other before they laughed, leaving a very confused Levi switching stares at them.

After a good few minutes of laughing, they stopped and heaved to catch their breath.

"That was so cool!" Rein said in amazement.

"Yeah, I wish that we can do that often!" Eren said in agreement as they looked at each other, past the raven sitting in between them.

The twins started to move their swings as the raven remained still. He glared at their legs, long enough to reach the ground and force the swing to move before looking at his own. The twins seemed to notice the lack of movement and Eren asked him in wonder. "Why aren't you moving?"

He glared at him but Eren didn't look affected. He looked down to his legs before moving it to his own then looked at Eren's face before looking at the ground. "I can't. My legs are too short." He almost whispered, some because of sadness and some because of embarrassment. He kept his eyes on the ground, waiting for the teasing that's to come.

Instead of doing what the raven expected, Eren silently stood up and gestured for his twin to do the same. Rein followed suit and they went behind Levi. Eren tapped the smaller boy's shoulder, causing him to look back.

"What?"

"Hold on, we'll push the swing for you." Without waiting for the raven's response, both of them pushed the swing gently, making the swing that's carrying the raven rock back and forth into the air. They continued it and laughed as they watch the smaller boy enjoy the rush of wind.

After minutes of swinging, the raven asked the twins to halt the movement. They did what he had asked, a wide grin on their faces as he looked at them.

"Why did you talked to me?" Confusion made its way to the twins' faces. "Huh? Why not? We wanted to be friends with you." Rein answered and Eren nodded in agreement.

"Why me? There's plenty of kids here."

"You're alone so we thought that you needed company."

"And besides," Eren added. "Nobody deserves to be alone."

That's how Levi made his first friends.

Years had passed and the trio's bond got stronger and stronger. They were almost inseparable, can always be seen together at all times. However, growing up brings a lot of changes.

Rein remained as the timid, intelligent boy that he is while Eren became some sort of troublemaker. Always getting into fights, always having to spend time in detentions. It always made his twin and Levi worry but it's not like they can do anything to change him. Levi's still the cold and stoic child he is, but his intelligence is unrivaled.

What didn't change is the bond of friendship between the twins and the raven haired teen, making many wonder how they got along considering how different they are. They always shrugged it off since for them, they're still the little kids who met and played at the park.

The feeling of friendship grew into something stronger, a feeling of love. Levi first felt this for the turquoise-eyed brunet, admiring the passion of the young teen. Rein is the one who made the first move to the raven haired teen, eventually leading to the reciprocation of feelings.

One event ended what hadn't even began. The Yeager family needs to move to Germany, forcing the twins to left Levi behind.

"Do... do the both of you really need to leave?" He looked up to look at the twins, a pained and sad expression settled on their faces. Levi's voice was full of desperation and sorrow, making it harder for the twins.

"We're sorry, Levi. We didn't want to but we were forced. We were too young to be left here." Rein's voice mirrored the same sadness his face is showing, his eyes became glossy from the tears he's holding back.

"Levi, we don't want to leave you. Dad's work required him to stay there so he's bringing us there with him." Eren's voice sounded just the same as them, if not, even sorrowful. Making the first move, he pulled Levi to his chest, letting the raven wet his shirt with tears. Rein joined in and the three of them was encased in a hug, not wanting to let go.

"Eren, Rein. It's time to go." Their mother's voice called them, making Levi hold onto the twins' shirt. The twins moved a little and removed Levi's hand from their shirt, holding it and squeezing it gently.

"We'll come back. We promise."

When Eren started to walk away, Rein hugged Levi again and kissed his forehead.

"Eren's right, we'll see you again. I love you, Levi."

He left Levi without another word, and that's the last time the raven-haired teen saw the twins.

"Hey, Levi, you're spacing out again."

I was pulled out of my reverie when Hanji's voice called me. I glared at them before I continued working on my assignment but Hanji isn't going to accept any of it. They placed their pen down and propped their elbow on the table, resting their chin on it and staring at me intently.

"You're thinking about them again, right?"

Looking up from my notes, I glared at them once again, meeting their gaze before answering, "No."

The look on their face became serious, clearly knowing that I'm just lying to fucking get away from the topic again, just like what I always do every single damn time.

"You can't fool me, Levi. I may have only known you for three years, but I can tell if you're lying or not."

I don't know if I should be glad that I told them about Eren and Rein. It's been five years since I last saw and heard of them and the hope of seeing them again became more bleaker as each day passed by. I sighed and slumped on my seat, both of my hands resting on the table curled into fists.

"Today's the fifth year that they left. I haven't heard any news from them since then. I'm just so fucking mad at myself for not being able to let go of their goddamn promise even though I know that it's hopeless."

"Levi, don't say that. Maybe they'll just come back one day for all you know. Just don't lose hope and besides, from what you told me, they seemed like a person who didn't break their promise."

As Hanji said those words, some of my memories with the two of them flashed inside my mind. They hate it when they're breaking their promise. Maybe I just need to wait for a little longer but, how long? Five years are so fucking long and I don't think that I can wait for much longer.

I just sighed and packed my things inside my bag before I stood up and swung my bag over my shoulder. "Hey, Hanji. Wanna go to the mall?"

"Hell yeah."

Just like what I offered, we went to the mall and strolled around the place. Hanji pulled me into different stores and bought some useless stuffs and I bought some shirts due to boredom. After we finished shopping, we went to a fast food next, ordering ourselves burgers, fries, and cola.

As soon as we finished eating, I decided to go home. Hanji and I separated ways considering we live in a different neighborhood. Deciding that I need to take a walk to clear my mind up, I started making my way back to my apartment in which I live in all by myself, music coming from the headphones I'm wearing.

On my way back, I saw the park where I used to play with Eren and Rein when we were still kids. My body acted on its own when it started to walk towards the park, my mind started to repeat my memories with the twins like it's some kind of movie.

I sighed as I sat on the exact place where they approached me ten years ago. There's no one in the park except me right now, considering how children nowadays prefer to use their gadgets than play in places such as parks. I can't help but chuckle when I looked down at my legs, remembering it's incapability to reach the ground and make the swing move when I was younger.

As I continued to soak in the silence, I heard footsteps coming from behind me and not even a minute had passed when someone jerked the swing I'm sitting on.

Anger rushed all over me when I recovered from the shock I felt. I stood up and turned around to look at whoever fucktard it is who decided to fuck with me.

"What the fuck do you think you're-"

I was cut off when I saw who it is and my eyes widen at the sight of a guy with a messy mop of chocolate brown hair with amber colored eyes. He's showing me that bright, wide smile that I knew all too well and I certainly believed that I'm just dreaming.

It's impossible, my sick mind is just making me see things that isn't here. I just missed them too fucking much that my mind is creating images of him. My mind went blank and the only word that slipped out of my mouth is his name.

"...Rein?"
