Big brother levi

Your POV

"Ok well done Lou. Now what's 7x7?" Levi asked me. I couldn't think of it. "I don't know." I whined. Levi looked around the room and after a while "ok let's try it this way. If I had 7 cookies and I timesed then by another seven cookies, how many cookies would I have?" Levi spoke slowly, putting emphasis on the word 'cookies'. It didn't matter if it made sense or not. The key word was cookies. "49! It's 49! I know it is!" I screamed throwing my hands up in the air. He just chuckled and ruffled my hair. "I'm tired Levi. Can we go to bed now?" I asked rubbing my eyes. As a small five year old I didn't know a lot. Levi being 12 always took care of me and taught me things. I loved Levi very much and I hoped we wouldn't be separated.

Time skip 4 years .

I ran through the streets with a bag in my hand. I heard shouts behind me but I didn't pay any mind to it.

I ran through twist and turns in order to loose the men. I finally made it to my house. I ran up the steps and knocked nine times. Levi and I had a code. We knocked the amount of years we were alive. Or at least I did. Levi just knocked nine times as well. He couldn't be bothered to knock 16 times so we decided to use my age. Levi soon opened the door and let me in locking it after me. "How many?" He asked i answered almost immediately "16 ironic eh?" I stared. He looked at me in utter disbelief. "Love to too big bro." I smirked rolling my eyes I walked to the staircase and cleared my throat. "OI ISABEL, FARLAN! GET YOUR WINEY ASSES DOWN HERE YOU NOB HEADS." I yelled up the stairs I turned around smirking. "You shouldn't yell like that Lou. And you shouldn't be swearing like that you're too young." My smirk dropped and I walked past him. "I don't like her, you know that." I took a deep breath and passed him. I don't know if I'm jealous or what is going on. Maybe I'm scared he'll leave me. She's not a bad person I just don't trust her yet.

Soon I heard them walking down the stairs as I prepared the food. We had a loaf each. It was to last 3 days but it's probably gonna be gone by then. Levi splits the food. I steal it. Isabel eats it and Farlan just helps. Me, sometimes Levi but mainly Isabel. "Omg lil sis can I have extra I'm starving." She whined. I mentally groaned but remembered what I promised Levi.

Flashback.

"I don't like her." I said glaring at the girl before me. She chuckled nervously. "That's not nice little one. Girls like you should be more polite. Especially taking into account your age." I glared daggers into the side of her head as she looked around. I slowly walked up to her. "Lou no." Levi said calmly but I ignored him. "What are you doing Lou?" Farlan asked. I smirked as I stood in front of her. "Playing a game." I said in a creepy voice. She looked down at me in fear.

I was on her back with her hand bent behind and her face on the floor. She groaned as I may have kicked her face and stomach a bit. "what was that about my height? Never insult me. This was a mild warning. I didn't even get to use my knives." I fake pouted. I suddenly felt myself getting pulled away. I looked up to see Levi. I frowned. "Ok I think that's enough." Levi said in his monotone. I nodded and stood in front of him. "Promise me you won't hurt her without reason. Good reason." He whispered. I just nodded "promise." I whispered back. I watched as she got up. "Thanks Levi bro!" She smiled at him. Levi bro? Oh hell no. I was ready to charge at her but Levi kept me back. He was struggling though. I finally gave up and left without warning. No one asked no one called after me. They knew me by now. I needed to cool off.

End of flashback

"No. you'll get fat and get killed. Not that I would mind." I murmured the last part. She looked at me in shock. She's been with us for about 3 days and she's acting like we're best friends. We're not. "Don't be cruel." She retorted as I walked back to the kitchen. I stopped dead in my tracks. I turned my head slightly sideways as I smirked. "You don't know how cruel I can be. This is my good side. Don't get on the bad one." I said in a threatening tone. I had a dark aura around me and I could see she was scared. I turned back around and kept walking like nothing happened.
