Torn - Finn Wolfhard x reader

The final scene

I sit in the passengers seat staring out the window, the landscape blurring. I'm full of so many mixed emotions. Today is the final day of filming, we're filming the final scene set at the lake. It's also the last love scene between mine and Richie's character since he's going to be moving, they'll be lots of tears. It's going to be super fun to film because I get to kiss Finn but it's awful at the same time. This is our last day of filming and I'm really going to miss working with all of my best friends.

Suddenly the car stops. "We're here." My mum announces pulling up to set. I kiss her cheek and grab my bag, I wave as I walk away from the car. Finns waiting for me holding his bag.

He pulls me into a hug, "excited?" He asks as I pull away to look up at him.
"Yeah, lets go." I say grabbing his hand and walking towards the lake.

~AFTER FILMING~

"Oh my god!" Jack screams, "were done!!!" Everyone's screaming and patting each other on the back. I run over to Finn while he's drying off. He looks really upset.
"Come on, we're all going to Sophia's house to celebrate the end of filming." I say wrapping my arms around his waist, I look up at him, he's not saying anything. "Finn? What's up?"
He pulls away from me and rubs the towel through his soaked curls. "It's nothing, I don't want to ruin today."
"Just tell me, Finn." I say. He looks around to see if anyone's watching before dragging me a few metres away from everyone else. "What's going on?" I say with a nervous laugh.

"I'm leaving." He stares into my eyes, tears rolling down his cheeks.
"Wait what?" I say shocked.
"To film stranger things season 4, I'll be staying in Atlanta for like 6 months." He cant even look at me. "It's just we've fixed everything and everything's so perfect. I'm going to miss you so much."
I can't even talk. I just pull him close and nuzzle my face into his chest, wrapping my arms tight around him, I don't want to let him go.
"When do you leave?" I mumble.
"2 months."
"Oh Finn."
Then we just stand there, holding each other. I don't know for how long but eventually I hear a cough behind me.

"Er guys?" A voice says, we turn around to see jack stood there, "we're all heading to Sophia's now, are you coming?"

We both nod and Finn puts his arm around me as we walk towards jack. I look up at his sad face. I don't think I can deal with him leaving me.

What am I going to do?
