Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝚂𝚌𝚑𝚘𝚘𝚕 𝚂𝚞𝚌𝚔𝚜 ( 𝐈 )

Y/n's POV:
 

~ MONDAY ~


" see ya mom! "
I shouted making my way to the front door.

Another weekend over, which means another day of school.
Anyways, I passed the living room, avoiding anyone who could stop me.

"Not so fast, Y/n!"
 I heard her yell from the kitchen.
" But mom!!! "
I growled rolling my eyes.
"You know when it rains, you're riding with your brother."
 She said, not looking up from her phone.
"I can walk. Besides, it's drizzling! Also, he's not my BROTHER!"
I replied wanting to leave. I do not, I repeat. I do not, DO NOT want to ride
 with Finn to school.
  " I'm serious mom, you know things aren't gonna end well.
 We're gonna argue the whole fucking time!! "
I argued taking my beanie from the rack.
" Do not use that language with me.
You'll both have to get along at some point. The Wedding's next month and I hope to
expect you guys to get along. "
She responded calmly.

Now I love my mother with all my heart, she's the best.
 But she got together with my soon-to-be dad, Eric.
 Yeah he's nice and decent and I know he cares about my mom so I got no problems with him except one.
 Sadly, he came with one of THE WORST PEOPLE I have met in my entire life.
Finn.
Now the name isn't bad, it's the person
WHO HAS IT IS!

Uughhhhhh!!

" And maybe you guys should leave now since it's almost 7:30. "
She added sipping her coffee.
" You have got to be kidding me! "
 I stomped up the stairs making my way to my step brothers room.
And once I was there...
 " Finn!! Wake the hell up!! "
 I shouted as I continuously pounded on his door.
 " Finnnnn!!! "
 I checked and it was unlocked.
 " Finn, wake- "
 I opened his bedroom door only to see him shirtless, wearing his black ripped jeans
 by his closet.

Fuck he's gotten hotter than the last time I saw him shirtless,
which was like last month...

Wait, what?
 SHUT THE FUCK UPPPPP Y/N!!

 " What? "
He asked, annoyed.

 Now, Finn...
How do I even begin with this asshole?
Well...
He's not nice to me one bit, he's the most annoying
and the most excruciating person I know!
 We've both fucking hated each other since the very first day
he stepped into this house.
 Until now too.
And lastly, he's becoming my step-brother which makes this
 10x worse.

 Back to the story...

" Mom said I should uhm ride with you since it's uh raining. And- "
" Why? Can't you walk? It's barely even raining? "
He interrupted me.
"You don't think I said that?"
 I shot back.
"Fine. Just wait in the car. Turn it on, will ya?"
 Finn said while he tossed me his keys.
"Uh we- we should leave now before we're late... "
I stuttered, trying to avoid eye contact.
"Just fucking go?"
He retorted walking into his bathroom.
   "Asshole. "
I scoffed making my way down the stairs.
  " Soo? "
My mom looked up from her phone.
"Just gonna wait for him in the car. Bye!"
 I said leaving the front door but,
" I don't want you walking back home either Y/n! "
 I heard my mother shout from inside.
" I can't believe he's fucking driving me to school. "
 I mumbled to myself as I made my way to the driveway,
and into his car starting the engine.
It's been about 5? or 8 minutes since I got in the car.
But finally, Finn arrived.
He came in tossing his school bag in the back and soon we drove to school,
not saying a word to each other.
  I just looked out the window and noticed it started pouring and the rain got heavier.
" Still wished you walked? "
Finn laughed, breaking the peace that was in the car.
"Soooo fucking funny, Finn. But yeah I still do."
I rolled my eyes, wanting to be at school already.
" Hey, don't blame me. Mom said so herself. "
He chuckled as we took a turn.
  " 'Mom said so herself' "
I mocked him and I was laughing mentally.
  " Real mature. "
He scoffed and I noticed he finally looked at me.
Could this day get any worse??
I'd rather fucking walk in this type of weather than ride with my asshole brother.
" You know. It's really stupid how you don't even have
a license to drive.
We're practically the same age. "
He mentioned, making me 10 times as pissed as I was.
"I was going to get a fucking license."
 I retorted.
" Oh right. But you failed your driver's test. "
 He laughed.

That's it.

" You know what, just drop me off the sidewalk. "
 I said slinging my bag over my shoulder, getting ready to leave this son of a bitch.
  " You're joking. "
a stupid smirk on his face he turned his head to me.
  I gave him a look.
"What? Are you crazy? It's raining Y/n- "
" Just drop me off the fucking side of the road, Finn. "
I scoffed cutting him off while I put my hood over my head.
  " No Y/n. As much as I want to- "
He laughed. "-I'm not gonna do that. And- "
 I heard him go on and on about how if he did,
 mom would ground his ass.
But his words faded out and it was just my thoughts
 that I could hear.

 I hate him, I fucking hate him! I- I just wanna leave and go to school!!

I looked out the window, ignoring Finn's useless lecture,
 and saw that we were somewhere safe, and school would just be a few blocks away.
But it was raining, hard...
 What I'm about to do is batshit crazy but it's fucking worth it.
" Y/n? Hello?? "
Finn spoke and I guess he knew something was up.
 I breathed heavily and opened the car door, hearing Finn call my name as I jumped out.
" Ow, Fuck! "
I seethed through my teeth, as I tumbled
and rolled by the sidewalk, landing in a puddle.
My left cheek scraped the pavement
 as I stopped.
I guess you could call that a pretty safe landing.
  Nothing was broken, and nothing hurt except my left cheek...
I got up, brushing myself off, immediately getting soaked from the rain.
" Shit. I did not think this through. "
 I sighed looking up to the sky, unsure of what to embrace.
The fact I wasn't riding with Finn anymore, or that I jumped out of a moving car.
Maybe both??
But that's when I felt someone shaking me.
" What the fuck was that for!? You insane!? "
Wow... Not even an " Are you okay? "
" What do you think? "
I said pushing his arms off and started walking.
" What the fuck is wrong with you?!
Jumping out of a moving vehicle!?!
Get in the car Y/n! It's raining! "
 I heard him shout from behind, and he was for sure well, we were definitely
creating a scene...
" I' d rather fucking walk than be in the same car as you! "
I shouted and sped up my pace while I passed his car.
I checked my watch and it looked like I was gonna miss the first period.
 Great...
" Y/n! We're already late for school!! "
He shouted but I ignored him and continued to walk in the pouring rain.
This was worth it right? I'm sure he doesn't even care
if I was hurt or not.
I mean it's Finn...

Suddenly his car showed up on the road,
 following me slowly.
Then the passenger window rolled down.
" Y/n, just get the car! Mom's gonna kill me!
  Listen, we're already late for school and you're soaking wet! "
I heard Finn yell.
" Yeah, no shit asshole! "
I yelled back, speeding up.
" I'M YOUR BROTHER SO YOU MUST LISTEN TO ME! IF MOM FINDS OUT-"
He yelled louder from the car.
" BULLSHIT! "
I shouted as I continued walking faster.
" Please Y/n! I'm sorry! Just get in the car! "
 " No Finn! You're not sorry!- "
 I stopped walking and his car stopped too.
" -You- you don't fucking mean that! Go ahead and drive off for all I care!! "
I continued walking feeling tears form in my eyes.

God, I'm so sick of him.

  " Please Y/n!?! I- "
" Just fucking leave Finn! "
I shouted looking down, tired of arguing.
" But- "
 I heard him speak but that's when he drove off.

Typical...

 " Fuck.. "
I breathed out taking my hood and beanie off since it was useless to wear it
when I'm already soaking wet.
It's been about 10 minutes of walking and a few more turns
and I was soon at school.
 I walked through the empty halls, heading to my locker to put my bag and beanie in.
  But that's when the bell rang.
Perfect timing!
  Seeing other students come out of the classrooms,
getting ready for the next class.

  " Y/n! "
 I heard someone shout my name, It was Brand.

  Brand Johnson.
He's been my best friend since we were in pre-school and he's the one I'd hang out with
both in and outside of school.
  Cool thing is that his mom and my mom were best friends since high school,
 we pretty much grew up together.
Brand always had my back, and I had his.
  Oh and the best thing about him,
besides being the best,
is HE HATES FINN TOO!

  After we both spotted each other,
he started running towards me, and he looked worried too.
"Hey."
  I gave him a weak smile as he walked next to me. 
" Jesus, you're soaking wet. "
He laughed but it soon died down when he knew what was up.
" And your cheeks kinda bleeding? "
 He brushed his knuckle on my left cheek seeing he wiped a little blood off.
But I kept quiet, not knowing what to say...
"What did Finn do this time?"
 He asked leaning on the other lockers.
" Being an actual dick as usual. "
I rolled my eyes taking my hoodie off.
"Why are you all wet tho?"
 He asked. "
I jumped out of the car and walked to school."
I replied looking down,
 hoping he wouldn't make such a big deal out of it.
But no, of course not.
" What??!! Are you hurt?? I mean besides your cheek! Are you cold?? Do you need- "
 " I'm fine, Brand. "
I groaned looking at myself in the mirror that I attached to the door.
" But- "
 " I said I'm fine. Will you just- just accompany me to class? "
I contorted my face, closing my locker.
"Yeah, yeah, sure."
 He nodded while we headed to class for second period.
" Pretty cool you jumped out of a moving car though. " 
He pointed out making the both of us laugh as he
wrapped his arm around my shoulder helping me turn through the halls.

Finally, we arrived in the classroom,
 and we sat next to each other.
That's when I remembered I had the same classes as Finn,
therefore I'd see him in the classroom...
 " Don't worry. You're gonna be fine. Just ignore him. "
Brand gave me a warm smile while I nodded and we waited for
 everyone to settle down.
  That's when I saw Finn and another one of his
slutty girlfriends kissing as they walked in.
" Gag me with a fucking spoon. "
I whispered turning my head to Brand and then facing away from the door.
" Mr. Wolfhard and Ms. Chambers, maybe you two could keep
 your tongues away from each other just for a little while?
I would want some decency in my class. "
 I heard Mrs. Lawrence speak, hearing a few students laugh including Brand.

The girl he was just making out with,
gross, I know.
  She's the biggest bitch in high school and I heard she has
the most body count which includes my dumbass brother
who doesn't know she's just using him to get more popular
since Finn was quite popular himself...

I looked and saw Finn staring at me
as he pulled away from that slut.

They're both using each other...
 It's funny honestly.
 Why can't he date someone "decent" for ONCE!
I'd appreciate it if you ask me.
Like someone decent like me-
-What??

I turned
 my head away and looked out the window
thinking about what happened earlier...
"Alright, kids settle down!"
Mrs. Lawrence announced to the class.
I can't wait to just do something. Something that'd get my mind off Finn.
God, he's such a fucking asshole how I wish-
 " Y/n? "
 I heard someone say my name but I brushed it off.
" Ms. Steele? "
Oh shit...
 " Dude! "
I felt Brand nudge me.
"Yeah um, yes?"
I sat up straight from my desk.
  "Are you with us?" Mrs. Lawrence asked.
" Yeah, yeah. "
I nodded feeling so out of it...
 " Alright. Anyways, going back to the... "
He continued and we started class, talking about history and shit. I was mostly zoned out and thankfully we didn't have to take down any notes.


~ 20 minutes laterr ~

" Class dismissed.
And Ms. Steele, I want you to stay for a while.
 Just need to have a word with you. "
Mrs. Lawrence spoke catching my attention,
while everyone got up, except me.
Brand said he'd wait for me in the cafeteria and I nodded.
I stood up from my seat and walked up to her desk.
"Yes?"
 I asked while she looked up from her laptop.
"Are you alright? In class, you weren't really paying attention?
Did something happen before you left for school?"
She sweetly asked me and I shook my head.
"Your left cheek is bleeding dear. And you're soaking wet. Are you sure?"
She asked again, I kept quiet.
  "I could call your mother for you if you like-"
She added making my eyes go wide.
" OH, no no no! "
I defensively declined, causing her to raise an eyebrow. "
I- I mean no, no Mrs. Lawrence. That won't be necessary.
  I just didn't have a ride to school so I had to, walk. That's all. "
I paused, slightly lying.
 " Okay well. Remember to pass your homework from last week.
You have until Wednesday to submit it. "
 It was Monday...
We only have half a day of class cause of some event the school has,
but that's not the point...
 " O- okay. "
I nodded and walked out of the classroom
 heading to the cafeteria.
I am gonna kill him when I get to the house.
I swear to GODD I'm telling mom and his dad, EVERYTHING!
 " Fucking Hell! "
I whispered shouted while I walked through the doors of the cafeteria.
From a far, I saw Brand waving his hand up from a table.
I was making my way there when I tripped over something,
  hearing some people laugh.
I looked to see it was one of Finn's friends who made me trip
 with his foot.
That bitch Sydney
was laughing her ass off next to him,
but the weird thing was that Finn wasn't...
" Alright, guys. Quit it. "
 He stood up and started walking over to me.
What the fuck is he gonna do?
  "You okay?"
He held out his hand.
What the fuck is this? He's an asshole before we get to school
 and now he's being all nice??!
Is this some kind of joke?
  " Y/n, are you okay? "
 He repeated, I looked around to see some people
 still laughing, some even having shocked looks on their faces.
Especially Sydney's...
I was laughing mentally at her facial expression.
"Fuck off, Finn."
  I mumbled carrying myself up, then walking to where Brand was.
Hearing people doing "oooooh's" as I got up.
" Oh, holy shit! "
 He laughed as I sat in front of him.
" Badass! "
 He raised his hand for a high five.
" That was not badass. "
I chuckled taking a bite from his Mac and cheese.
  " What do you mean?? You know- Yo he's looking at you. "
 He paused his sentence making me turn my head and Finn
 was indeed staring at me.
" What? "
I mouthed, and he just shrugged his shoulders.
I contorted my face, turning back to Brand.
" What'd he want? "
He asked.
" Who fucking knows? "
I replied drinking some water
" And I don't fucking care what he wants."
I added as I ate some more of the macaroni.
" You guys are into each other. I know so. "
 He suddenly spoke making me choke and
 he started laughing hysterically.
 " What?! "
I asked coughing and drinking some water.
" Nothing. "
He laughed standing up.
" Where are you going? I'm not done eating!
  Don't leave me here! "
I pleaded, also stepping out of the seat,
" The store, Y/n. Where else? "
He laughed while we both walked out of school to hangout
since it wasn't raining anymore.
