Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙳𝟷𝟶𝟾

I didn't realize how much I was overthinking about this.
I couldn't eat. I couldn't sleep.
Brand would just go into Finn room and chill with me.
He would try to motivate and make me do something but it was no use.
Nothing worked.
" Y/n. You've gotta eat something.
Just get out of Finn's room it's been a day and you haven't touched a single piece of food that I've brought in here for you. "
I looked over to the table with 2 plates
of soggy food.
" Well what do you want me to do Brand. "
I say laying back down, curling back up into the blanket and hugging a pillow.
" Do something!
We got school tomorrow, you know? "
" Your point? "
I mumble, closing my eyes.
" Come on, Y/nnnnnnn!
Spend time with me rather than just sulking in your sadness cause of your boyfriend. 
Also, I'm leaving tonight too since my parents are coming back
 from The Bahamas. "
He mentioned and it made me realize.
He was right, and yeah of course I'm sad that he's already leaving.
The only company I have before my parents get back.
 Which is not until a week...
Why was I feeling this way?
I just wanted Finn home. If he doesn't want that then...
I guess that it's over between us.
" That's it Y/n. I'm going out to buy pizza and you're eating the whole box whether your ass doesn't like it or not. "
Brand stood up, picking up his jacket from the side table.
Next thing I knew I was alone in the room again.
I turned my phone on, seeing how many voicemails I've sent Finn. 
Am I being to obsessive? 
I thought, skimming through the recordings. 
" What's fucking wrong with me? "
Dragging my hands down my face, sitting up from the bed. 
I decided I'd take a shower,
hoping that it would make myself feel better. 

After so, I was getting changed and heard Brand arrive from downstairs.
" Y/n! Get your ass down here! " 
My best friend shouted.
Trying to admire myself in my mirror, I looked really tired. 
MY eyebags have never gotten this bad? 
Skipping down the stairs, I walk into the living room with 2 big boxes of pizzas.
Brand was in the kitchen pouring us some drinks. 
" Holy shit. 
How did you afford this? " 
I question him, I go closer and open the box. the smell of freshly baked pepperoni hit my nose. 
I felt like shit, but man oh man did this smell good.
" Let's just say I got a friend of a friend. " 
Brand smils, handing me my glass before he hopped onto the couch. 
" So, what we watchin'? " 
Crossing his feet by the foot of the couch, taking a big slice from the box. 
" I don't know? "
I sat across from him, setting my glass down. 
" Hand me the remote. " 
He asks, and in doing so, I do.  
Going to netflix, clicking one of my favourite movies that would always cheer me up. 
" Really? Ghostbusters?? " 
I question his choice.
I actually haven't watched this in awhile...
" Yup! Marathon baby! 
 Now dig in, Y/n! " 
My best friend laughed as he kicked my side with his foot. 
If was anyone who never failed to make me smile in any situation, it would be Brand. 
" Haven't seen you with that smile in awhile. 
Just forget about everything. 
Okay?
Now c'mon, get a slice. No one likes cold pizza, you weirdo. " 
Brand taking his second slice, I nod taking my first. 
We watched the first, and second movie.  

I haven't had this much fun in a long time. 
Man, am I  thankful to have Brand as my best friend.
It was already getting dark and well it was about time he started packing. 
We were both in the guest room, since I was helping him stuff his suitcase. 
" You know, apparently they're making a 3rd one!?? " 
My best friend adds. We were still talking about how a
people could not like Ghostbusters? 
It was a classic! 
" A THIRD ONE?! " 
I exclaimed, shocked since this movie was WAAAAY back in the 80's. 
" Yeah! It's coming out next year or so.
called Afterlife I think? Not sure. " 
He laughs, taking a shirt from the closet and plopping it into his suitcase. 
I smile to myself, closing his luggage and zipping it up. 
We bot headed outside on the porch, waiting for his parents to show up. 

" You know I don't wanna leave, right? " 
We both sat on the stairs. My chin rested on my hands. 
" I'll be okay. Don't worry. " 
I assure him but, 
" Yeah but like, will you? I don't want you home alone? 
I'll ask my parents if I could stay one more night- " 
Brand suggested, but I knew he couldn't. 
" Brand relax, it's fine. Besides, I know you can't cause we got school tomorrow. 
Remember? " 
" Fuck, right...
Well, I'll just come over after school tomorrow. "
He says happily until we heard a car pull up in front of the fence. 
" Hey kids! " 
A window rolled down, and there was Aunt Laura in the passenger seat. 
Smiling I stand up picking up his suitcase. 
I walk him to the fence, greeted his parents and his dad helped him put his suitcases in the car. 
" I'll try to come over tomorrow, okay Y/n? " 
Brand started tearing up. 
This guy- 
I laughed knowing how emotional he gets. 
" Shut up! You know I'm worried about you! " 
" Ow! " 
He punched my shoulder a little too hard. 
" Sorry. " 
Shaking his head, he pulls me into a hug. 
" Brand, I'll be okay! 
After tonight? I haven't felt like this in long ass time. "
I pull away from the hug. 
" Just- just give me a call, alright? "
He sniffled wiping his nose with his sweater. 
" I will. "
I pause, a warm smile appearing on his face. 
" Now go, before your mom whoops your ass. "
We both laugh. Brand entering the car. 
" Bye Y/n! Stay safe, okay honey?  "
Brand's mom grinned, caressing my hand. 
" Call us if you need anything, okay? 
We're a call away. "
Uncle Scott added as he got in the car too. 
" Thanks Aunt Laura. I'll be sure to. " 
I nodded until they were satisfied with my answer. 

Soon enough they drove away.
Leaving me standing outside my fence...
I forgot how cold it is here.
I hurry back inside and cleaned up the pizza boxes that were both empty by the way. 
Music playing from the Tv, I didn't feel sad at all as I was cleaning up. 
I hadn't thought of Finn once. Until my eyes spotted his suitcase that was knocked over by the side of the couch. 
I sigh remembering everything all over again. 
But I didn't feel as bad as I used to. 
Guess all I needed was pizza? 
I bring myself to carry Finn's suitcase upstairs and into his room. 
I tidied up n there too. Fixing his bed that I've slept in for the past 2 days. 
Finally threw out the spoiled food I didn't eat. 

Once I was done in Finn's room, well...
I didn't have anything else to do after that. 
Not having a clue on what to do, I ended up laying on my bed scrolling
through instagram reels till I fell asleep.
Setting an alarm since we got school tomorrow...
Not ready for that at all.
But ey, I got no choice now, do I? 
Feeling my eyes getting heavier by the second, 
and I fell asleep...


Hours Later ~


 I heard my phone ring and vibrate on my bed. 
Assuming I probably set the timer wrong.
But it was someone calling me, and that someone was Finn!
I immediately answer the phone, sitting up from my bed. 
" Hello? Finn? 
Are- are you going home? " 
I ask through the phone, my voice all groggy since I had just woken up. 
Waiting for him to answer, but there was no response... 
" Finn? "
I say his name. 
" Are- are you Y/n? " 
A different voice answered me and this definitely
 wasn't Finn's voice.
I'm sure that it was a guy? 
He sounded high pitched and had a little raspiness in his tone.
" This- this is she? Who are you, and where's Finn? "
My questions flooded as soon as he spoke. 
" I- I'm Jack, Jack Grazer.
I'm a friend of his. Uh... "
This was Jack?
I stayed quiet until he spoke, 
" Your his sister, right? "
He asked in a question tone. 
I noticed he spoke extremely fast. 
It was hard to understand him, but I somehow managed to. 
" Yeah- yeah I am. "
Then it hit me. 
Shit. 
" What's wrong? Did- did something happen to him? "
Worried, I stood up from my bed. 
" Not- not really? " 
He stuttered and I heard murmuring in the background of the call. 
" What- what do you mean? Is he alive?! "
At this point I was shouting through the phone.
" No! No! He's fine, kind of. " 
He paused, which confused me ever more. 
" Huh? " 
" I- I- I mean he okay but Finn. He's- he's not in a good state
 at the uh moment. " 
" What happened? " 
" It's uh- it's hard to explain. "
This kid could not get his words STRAIGHT! 
" Well, can I talk to him? "
I ask and it tok about 7 seconds till he answered. 
" He's passed out on the floor. 
I- I think he's drunk. "
Finn, drunk? 
Why would he be- oh that's not important right now- 
MY thoughts were cut off when he, 
" Anyways- I uh- I called call you over. He just said to call you
if anything bad would happen to him. "
I think I'D DIE if I found out Finn wasn't alive. 
" Can- can you go here? "
The boy stuttered again. 
Without even thinking of a way, I agreed.
But I had to! I had to ask!
" Why is he drunk? Did you guys drink or something? "
" No! He- he just showed up this way. "
" What!? "
I'll- I'll just explain later once you get here. "
" I'll text you the address, okay? "
" Alright, bye. "
He ended the call.
