Childhood friends (eren x reader)// not going to finish

Prolouge

My dad and I waited on Dr.Jaeger's porch. Your dad and him were good friends and worked together often as doctors.My mother recently died. She was in the survey corps and was eaten by a titan.
"Now, you know what's gonna happen. Since I go on  trips often your gonna stay with Grisha and his family. I want you to think of them as family too. Since when I'm on trips, you need somewhere to stay. Here. There is a boy and his adoptive sister, you three are the same age so I want you guys to get along understood?" I nodded. I was nervous, excited, and scared at the same time. Hopefully they won't hate me. My dad knocked the door. A few seconds later, Grisha opened the door.
"Akio! And (y/n)!" he greeted.
" H-hello." I said shyly.
" Are you fine with her almost living here?"
"Yes, I'm fine with that!"
"Okay, (y/n). If I don't leave now, I'll miss my ship. Are you okay with staying here?" You nodded. In fact, you were pretty excited.
" Okay bye (y/n)" My father kissed you on the cheek and went to the ships.
"(y/n), leave your stuff over here and come in!" Grisha invited.
"O-okay." You putt you bags next to the door as he told me and came in. There was a boy with turquoise eyes,and brown hair. H e stared at me with a smile excitedly. There was also a girl with black hair and eyes. She was smiling. The boy stared at my hair. my hair was different, the ends were a mint color and even if I cut the ends, the mint grew back. Dr. Jaeger and your father were marveled at it and tried studying it, but there wasn't anything different from other hair.
" Your hair is so cool!" He said " Did you dye it or something?"
" Oh, no it's just like that. Even if I cut off the colored part, the ends will turn mint too! It's weird I know."
" It's not weird!" he declared
" I think it's pretty nice." The girl chimed in.
" Thanks... Mikasa? And Eren is it? I think your eye color is cool too! I have never seen a eye color like that!"
" You know our names. And thanks! (y/n) right?" I nodded.
"Kids! It's time for lunch!" Carla announced. She set down a sliced chicken. 
"Where do I sit?" I chirped
"Wherever you please, we just sit wherever we want." Carla answered.

Time skip to after lunch 

Eren  and Mikasa lead you upstairs. There was a hallway with several rooms. He led you to one that was fairly large and had two beds. you guessed it was mikasa's
"Alright you will be sleeping here since you and Mikasa are girls and her room is bigger than mine." Eren declared " My room is on the right by the way." Eren left the room.
"Mikasa are you fine with this?like letting me sleep in your room?"
"Yes, I hang out with eren and he has one friend.  I've always wanted a female friend too."
"Then let's be friends! I don't really have any friends either..."
