Hello, readers! So, this fic will start with Eren and Levi when they were children and eventually continue on until they're teens. First chapter of many! This will be in an Alternate Universe, as well. Now, onto the story and I hope you all enjoy!

Eren Jaeger was a happy child. He would willingly participate in activities at his school with his classmates and stand up for the ones that were being bullied. Eren was both strong-willed and fairly laid back, unless one of his friends were being made fun of. In that case, if you never saw Eren outside of school or knew what his life was like outside of school, you would think that he was the bully. Eren's best friend Armin Arlert was an easy target for the mean kids, just picking the right time to pick on a kid like him.

That's when Eren would usually step in. For example, it was just last week that he had gotten into a fist fight with one of the biggest bullies in the school: Auruo Bossard. Okay, that kid was just creepy. Auruo always wore a smile like he was happily about to murder someone, and his skin wasn't all that perfect, either. He always wore somewhat nappy clothes, though he still continued to rank himself as the toughest and best kid in the school.

But, all of that is besides the point.

Eren Jaeger was a happy child. He lived in a neighbourhood with his best friend Armin, and was very active. Him and Armin and his, younger by a few months, sister, Mikasa, would go outside and play for hours and hours on end, laughing and falling and playing silly games. But today.. Today was different for Eren.

The young boy was walking home from school, along with Armin and Miksasa. There were quite a few roads and backroads in the neighbourhood, and Eren was very confused at the beginning when he first moved in, but now, he knew the streets like the back of his hand, and it was time for Armin to part with Eren and Mikasa.

"Bye, guys! I have to go home now." The little blond informed the two, gave them both quick hugs before stepping back a bit, towards his road. "Maybe I can have a sleep over tonight?" Eren chuckled and Mikasa smiled softly.

"Sure, Armin! You know how mom loves you like one of her own!" Eren replied, a grin on his lips as he watched Armin nod and giggle.

"Cool! See you later!" The blond called one last time before turning on his heel and begun to jog home. Eren could only smile and shake his head at the boy.

"What a cute little idiot he is."

Mikasa giggled quietly into her scarf wrapped around her neck. Eren turned back to Mikasa and gently grasped her hand within his, and continued walking on home. Squeezing the other's hand a bit, Mikasa strolled beside him silently.

When the two had reached their road, they were both a bit confused to what they were seeing. A couch was being carried into the house beside their's, from a big truck. Could it be..?

"New neighbours?!" Eren exclaimed, that excited grin coming back to his features.

"Looks like it," Mikasa replied, her voice her normal tone. She didn't mind new neighbours, unless they were noisy. The girl didn't have much more time to think before she was suddenly being dragged into her house by her brother. The front door was swung open, and there was Eren and Mikasa's mother, washing dishes with the faint sound of classical music being played.

"Oh, you two are home! How was your day, Eren? Mikasa?" The brown haired woman asked the children, and begun to dry her hands.

"Mom, there's new people moving in next door!" Eren exclaimed, jumping slightly in his place.

"My day was good, mother. I'll be upstairs." Mikasa replied, prying her hand from Eren's and quietly slipping upstairs. Mother and son watched, somewhat curiously as the young girl slipped upstairs, but both decided not to question it.

"Yes, Eren, I've seen! And you know what? I've heard a new kid is there, as well. I think he's around your age. Maybe you should go say hi!" Carla Jaeger ruffled her son's hair, smiling a sweet smile. Eren's eyes only widened.

"Really? Can I?" He asked. Carla nodded in reply. "Awesome! Thanks, mom!" Eren exclaimed, and quickly removed his backpack and tossed it beside the shoe rack by the front door. Just as he left the house, nearly sprinting, Carla called.

"Just don't stay out too late! Dinner will be in a few hours!"

Eren glanced back at her and waved.

"Yeees!"

The boy, within a few seconds, was already at the next door neighbour's front door. Eren raised his hand and gave a few knocks on the nice, wooden door. A moment later, the one who answered the door was a child (his mom was right! He did look about Eren's age) with short black hair. Eren fumbled with his words for a moment before flinging out his hand to greet the other.

"H-Hi! You're my next door neighbour! My name is Eren Jaeger."

The boy fidgeted, a bit nervously, as the eye contact with the other child slowly became more and more unbearable. Eren was just about to turn away from him and go back home, but he suddenly felt a fabric grasp his hand and squeeze it. Eren blinked door at their linked hands.

The other kid had.. Covered his hand with his sleeve?

".. Um.. Why are you covering your hand like that?"

"I don't know what kind of germs you have on your hands." The other kid replied boredly, his voice monotone. It almost made Eren shiver.

The two stood like that for, what Eren thought was hours, just staring at each other and squeezing one another's hands. The silence was thick, until the mysterious child decided to break it.

"... I take it you want to come in and 'hang out'?" Eren was a little taken aback about how.. formal he was being, but he couldn't deny that he was right.

"W-Well.. Yeah! I mean.. if you don't mind!" The brown-haired boy raised his free hand and sheepishly rubbed the back of his head, grinning uncertainly. After a few more moments of silence, the other kid removed his hand from Eren's and opened up the front door a bit more, silently welcoming him in. It took Eren a few moments to figure out what he was doing, but it soon, quickly clicked.

He stepped in, giving the other child a nod of thanks. He slipped his shoes off on the mat was that was placed inside, in front of the front door, being the respectful little child he was. The other closed the door behind him, and gave a quiet sigh.

"You wanna come up to my room?" Eren nodded, his previous nervous grin beginning to be replaced with a somewhat more relaxed smile. The other child nodded, and motioned to Eren for him to follow him.

The two walked up the stairs of the house and turned a corner, and there it was: his room, on the right side of the hall. They entered the room, and Eren could clearly see that this family had literally just began to move in today. In his room, there was only a matress on a bed frame, a book shelf, and tons of boxes. The walls were cream coloured, and the carpet felt soft underneath his feet. All in all, Eren already began to like the kid's room.

"Oh! Um.." Eren began, that causing the other child to turn to him.

"Hm?" He replied, cocking an eyebrow.

"I, um.. I don't know your name yet! Let me re-introduce myself.." Eren stuck out his hand once again, giving a big grin. "My name is Eren Jaeger, and I'm your next door neighbour!"

The other child was quiet for a few seconds, until Eren saw him raise his hand and hesitantly grasp his hand, without covering it this time.

"Levi.. Levi Rivaille."
