Modern AU
Eren and you were best friends ever since y'all were little. From the first day you two met Eren promised you that nothing could tear you guys apart. When you and Eren were little kids you would have each others back.
**when you and Eren were 5**
"(Y/n)! I made us something!" Eren said running towards you. You were outside in your front yard playing with a stick. Eren lived 3 houses before you. Your mom and dad and Eren's mom Carla and his Dad Dr. Grisha Jaeger were great close friends. You looked up at Eren. "What did you make!?" Eren smiled and said. "Close your eyes and hold out your hand!" You did as you were told. You were filled up with excitement. "Okay open them!" He happily said. You opened your eyes. In your hands laid a bracelet that said best . It had (fav. Color) beads and emerald green beads. "Oh Eren!" You squealed. "Its so pretty!" You hugged him tightly. "I got one just like it but it says friends! You looked atvhis bracelet it said "frands"So when we put our hands together it says best friends!"Eren said. "Never take it off (y/n)! Promise me!" He said. You looked him in his beautiful greenish eyes . " I promise." You replied. "I will never take it off." "Pinky promise?" He asked. "Pinky promise." You and Eren made your pact. Best Friends Forever.
.
You and Eren had your ups and downs but you guys got through those things together.
*A month later**
It was the first day of school for you and Eren. Your first day in kindergarten. You were so excited. You were a daddy's girl. You were tough and stood up for yourself. You lived in a friendly neighborhood. It a small city like town but your father was raised in the country. He was a hardworking man. He took you to your first hunting trip that summer and he taught you how to shoot a gun. ( obviously you used a smaller one than he does). Him and your mom had a little argument about you using guns and how that could come back and bite him in the ass one day. He told her that you need to learn survival skills and that when he was a young boy he learned at the same age and how it was so useful to him. Your mom was a young woman from the city. She was very protective over you.
"Alright little princess," your dad said "you ready for school?" "Yup!" You answered. "Alright let's go!" Your dad took you and Eren to school. " Take care yall." He told you and Eren. " Stay out of trouble."
"I will," Eren replied. "I can't promise anything!," you replied. Your dad smiled and left.
You and Eren where in Miss Ral's class.
You and Eren sat in a empty table together. Eren smiled at you once he seen you were wearing the bracelet that he had made you. He was wearing his too. You spent morning learning colors and the alphabet. Learning how to spell some words. Soon enough it was time to eat lunch. You took out your Thor lunch box and Eren his Batman lunch box. After it was time for recess. Eren made his way to the slide until some kids bigger than him pushed him off. Then they followed him and started to kick him.
Anger was rising inside of you. So you walked over to them boys and gave them a fist to their faces. You winked a Eren. You kicked of the boys in the crotch and you were on top of the other boy beating the shit out of him. Then you heard Eren sniffing and telling you to stop. You didn't listen to him until someone pulled you off that rat looking kid. Next thing you know you were facing the school's vice principal Mr. Levi Ackerman. He took you by the hand and dragged you into Mr. Erwin Smith's office. You were looking at the floor.
Mr.Smith spoke first. "What's your name?'
"(Y/n)." You spoke softly not looking him the eyes.
"Look at me." Mr. Smith spoke with soft words. "Why on earth were you beating up that boy in the playground?" Mr.Ackerman interrupted.
You had a good reason so you told them.
" They were beating up my best friend so I taught them whose boss."
Levi had called your parents and your dad was here.
"(Y/n) what did you do?" He sounded angry.
You told him everything. Good thing your father understood and he let this one go. Erwin and Levi and your dad had a grown up talk.
After that you walked back into the classroom. You gave them boys a death glare. They turned away. You sat at the table with Eren. He whispered to you. "Thanks."
"Anytime." You replied.
Soon enough it was time to go home. "Wow what a day." Your mom started to say when you got home. She gave you and Eren a snack. She asked you about what happened today. "Next time just tell a grownup." She smiled. When your mom turned around Eren said "Nah. Beat them.up." You laughed at Eren's comment.
"What would I do without you!" Eren said hugging you. Your dad and mom seen that and just awed.
Years passed and every year you had a fight with someone at school. Eren was always picked on. Then the person who picked on him felt your wrath.
