High School Sweethearts (Newt x Reader AU)

Lizzy |12

"Come on in Y/n" I walk in the door to see this huge entryway with a double staircase leading to the kitchen. I look up and see a beautiful chandelier. I take my shoes off and we walk up the stairs to the living room. Newt introduces me to Lizzy, she has golden ringlets like a doll with the same loving brown eyes. "Lizzy this is Y/n. Say hello." Newt says sweetly to his little sister.

"Hi Y/n," she says with a shy smile.

"Hi Lizzy. I'm here to help Newt babysit you."

"YAY! Now I have someone to play tea with!" she says, jumping up and down.

"Hey, I play tea party with you," Newt says.

"You don't do it right. You won't wear the princess crown." Lizzy says with a sigh.

"Wow," I say in shock.

"Wow, that's right. I thought I did a fantastic job at the tea party," Newt says while putting a hand on his chest and making a hurt face.

"Well you didn't," Lizzy says blankly.

"Well, what do you wanna do first?" I ask Lizzy.

"Barbies!!!" she says, pulling me to her room.

"I'll make lunch while you play," Newt says with a hint of joy in his eyes.

"Make mac n' cheese," Lizzy says with a big smile. Lizzy's room is full of toys and the walls are a light shade of purples. As we sit on the floor Lizzy instantly pulls out her giant collection of Monster-High dolls and hands me two dolls to play with. Not long into the playing, Lizzy starts to ask me questions.

"Are you dating my brother?"

"What! No, we are just friends." I say, laughing at the question, wondering how she even knows what that means.

"Aw, why not? Then we could play all the time," she says with a sad look in her eyes.

"It's ok we can still play all the time," I reassured her.

"Okay!" she says, as she goes back to playing like nothing happened. Newt walks in and tells us lunch is ready. We walk to the kitchen, which is all different shades of marble. It looks like it would cost more than my whole house. Newt brings three bowls of mac n' cheese to the island and helps Lizzy up onto the chair.

"Newt, why won't you date Y/n?" Lizzy says with confusion laced in her voice. Newt spits out his food in shock

"Lizzy, you can't just ask me that."

"Why?"

"Because...you just can't," he says, astounded that the question came out of his little sister's mouth. I just sit back laughing to myself while eating. I see Newt go red and I can't tell if it's from anger or embarrassment. Newt gives me a look of question before he goes back to eating his food. The atmosphere is swimming with joy and laughter as Lizzy throws us into a complete story of her dolls and all of the dramatic scenarios a four-year-old could think of. Watching Newt follow along and attentively listening to her, brings a smile to my face, seeing how sweet he is with his sister.
