Kayla's pov
Ever since my sister started dating Niles he has kept her to himself if I'm in the same car as them I have to sit by Niles because he sits in the middle, if we are at McDonald's they leave me in the play place so i can play before niles came into my sisters life i would always sit by her, and she would always be in the play place with me. Today is the day I tell Niles she's mine not his. They were currently in y/n's room doing something idk what but when I walked in my jaw dropped. Y/n was doing Niles makeup I was about to cry because she always did my makeup idk why she was putting makeup on him he's a boy he doesn't need any. I walked in and kept my tears back. Oh, hey Kayla y/n says. Hello my favorite sister I say loudly. Niles we need to talk, also you look like a smurf I say. Ok your done I'ma wash it off Niles said. Let me finish it, please y/n said. Fine Niles said. No I say then I did what I thought I would never do. I grabbed Niles by the hair and pulled him, he fell off the bed. Kayla, what are you doing? Y/n asked. I need to talk to Niles alone I say. Ok but be careful with his hair she said. Whatever I say. Ok, get up you bum I say. Why are you so aggressive Niles asked. Shut up I have to tell you something and I'm only gonna say it once..... She's mine not your I say. What? He asked. Don't act stupid Neumann, you are taking n/n away from me I say. You could've just told me kayla he said. I'm 5 years old, so I deserve most of her attention I say. Ok Kayla I get it, you need her attention because your afraid she will forget you he said. No, I just want some attention I say. Ok well you can take my place for the makeup because I look like a smurf Niles said. Ok bye I say and I skip into my sisters room. Kayla what did you do y/n asked. I just told him something I say climbing on the bed. That's nice I'ma do your makeup now she said. Do whatever I say

I've had a problem recently Kayla has been a little too clingy to me. I can't go with the team without Kayla because Niles is gonna be there. I can't sit by Niles because Kayla will always try to squeeze through us. And Kayla would always say the words "she's mine not yours" just like today I was with nelson Niles and Noah and ofc Kayla at shake shack. We were about to sit in the booth but before Kayla could sit I had to grab her. How about you sit next to nelson I say. Why? She asks. I wanna sit by Niles I say. Why don't you want to sit with me she asks. Because I sit by you every day I say. Fine she said and sits next to nelson. She's mine not yours Kayla said. I roll my eyes at her. She side-eyes nelson and he looks at her confused. What did I do? Nelson asked. Why are you looking at my sister she asked. Sorry damn I guess I'm not aloud to look at anyone he said. She belongs to me and Niles not you she said. I cover my face trying not to laugh. Yea nelson she belongs to us not you Niles said. I love these two but they are crazy asf.
