Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙰 𝚠𝚎𝚝 𝚍𝚛𝚎𝚊𝚖

I woke up to the sound of the doorbell echoing from the entire house.
Opening my eyes, I look to my left to see Finn still fast asleep.
The ringing from outside kept going on.
It was continuous...
" Shit. "
I mumble to myself, before lifting myself to sit on the bed.
I was rubbing my eyes so that I could wake up.
The doorbell continued to ring again, and again...
How the hell could Finn still be sleeping?
" Okay, okay. I'm coming.
Jeez. "
Almost fumbling down the stairs, I finally reached the front door.
I opened the door, seeing Brand standing outside with McDonald's in his hand.
" Woah, you okay? "
He was tilting his head to the side, laughing.
" Hey, Brand. "
A smile formed on my face as I leaned in to hug him.
" Sorry about pressing the doorbell multiple times.
you wouldn't answer your phone? "
I let him in, closing the door.
" It's fine. Uhm, what's with the food? "
I question, still half awake.
" Y/n, it's 3:47 in the afternoon. "
He paused.
It was already 4?
" And you didn't show up on the first day of school.
Well, orientation... "
The Brand continued, and he was already in the kitchen,
taking the food out from the paper bag.
The smell hit my nose instantly,
I felt my stomach grumble.

" Oh, is Finn still upstairs? "
Brand asked, which caught me off guard...
" Wait, how- how do know Finn's here? "
Confused by his words.
" You texted me last night saying he was home.
And that you picked him up at his friend's house? "
He answered in more of a questioning tone.
" I- I did? "
" Yeah, Y/n/n. "
He chuckled, going into the fridge.
I tried re-calling if I did text him.
I couldn't remember...
" Crap. "
I sit down on one of the stools by the kitchen counter.
" Alright eat up. "
Brand pushed a whole box of chicken nuggets and fries in front of me.
" Thanks, Brand. "
A pitiful grin on my face, opening the sauce.
" Yeah, no needa' thank me. I'm just gonna use the bathroom. "
Rubbing my back for comfort,
he goes into the bathroom.

I don't think food ever tasted this good...

Finn's POV:

My head was pounding...
I'm never drinking that much again.
Shit.
All I could remember from last night were parts.
It was all just a blur.
I remember going to Jack's place,
and then Y/n appeared outta nowhere.
Talked about us.
Then we...
We kissed in the car...
And she brought me home and then slept with me in my room.

Speaking of which...
Where is Y/n???

I immediately get up, and rush to the bathroom to check if she was there.
Almost tripping on myself, I zoomed out of my room and swiftly ran down the stairs.
I could hear Y/n talking and she was with someone?
The moment I stepped down from the last ledge of the stairs,
there she sat by the counter, and she was in fact not the only one there.
There was some other dude with her, they were talking.
I tried to recognize the voice, but I couldn't, and he was turned back,
so I didn't know who it was.
I felt jealousy take over my body,  but it quickly washed away
when the guy turned around.
It was Brand?
Her best friend?
What's he doing here?
His eyes immediately caught me, which made Y/n turn around.

" Finn, you're awake. "
Seeing that smile appear on her face,
made one form on my mouth.
She walked over and hugged me, feeling her warm hands hit my chest and stomach.
I know she's right in front of me, but I missed her.

" Hey. "
Wrapping an arm around her, we walked to the counter from the stairs.
" Hey, Finn. "
Brand shot up with a tight-lipped smile. I lower my head to Y/n's level.
" What's he doing here? "
I whispered asking her. But right as she was about to answer,
" You know I can hear you, right? "
Brand leaned on the table with his hands.
"  Okay? Then, why are you here? "
Crossing my arms, leaning on the chair.
" How could even- "
" Finn, Brand came by to check if I was okay.
If we were okay.
He showed up with some food too. "
She emphasized, her gaze going to Brand,
then back to me while she fed me a nugget.
Clenching my jaw as I chewed my food, I kept my eyes on Brand.
Seeing him gulp the lump in his throat.
That's all I needed.
I mentally laughed in my head, responding with,
" M'kay. "
I nodded before we all got to talking about how we're gonna sort this whole situation...
Since I just found out that our Parents would be going home tomorrow already.
AND that we missed the first day of school.
