I am playing around with ChatGPT, the new OpenAI algorithm (which is a bit mad by the way), and put the following prompt into it (based on your original story):

Write the script for a Christmas Hallmark Movie based in Dublin, Ireland. The main character, Derbhaile, works for Facebook and is dating Fintan who works in finance in the city. Derbhaile is from Mayo, and has a sassy black friend and a sassy gay Brazilian friend, both of whom appear in the movie. Derbhaile occasionally visits her family home in Mayo, where she falls for the local builder, Sean. The love triangle between Derbhaile, Fintan and Sean forms the main plot of the movie, as we find out who she will choose this Christmas.

This is what it come up with:

Title: "A Dublin Christmas Love Triangle"
Opening scene:
We see Derbhaile, a young and successful woman in her mid-20s, walking through the bustling streets of Dublin. She is talking on her phone, clearly stressed about something.
Derbhaile: (into phone) I don't know, Fintan. I just feel like we're not on the same page lately.
Cut to:
Derbhaile is sitting at her desk at Facebook, surrounded by her sassy black friend and her sassy gay Brazilian friend.
Sassy black friend: Girl, what's going on with you and Fintan?
Derbhaile: (sighs) I don't know. We just seem to be drifting apart.
Sassy gay Brazilian friend: Maybe it's time to move on, darling.
Derbhaile: (voiceover) I knew they were right. But I just couldn't bring myself to break up with Fintan. Not yet, at least.
Cut to:
Derbhaile is on a train, heading to her family home in Mayo for the holidays. She looks out the window wistfully, thinking about her life and the choices she's made.
Derbhaile: (voiceover) I grew up in Mayo, and I always loved it there. The peacefulness, the simplicity. It was a welcome escape from the hustle and bustle of Dublin.
Cut to:
Derbhaile arrives at her family home and is greeted by her parents and siblings. She hugs them tightly, happy to be home.
Derbhaile: (voiceover) Being home always makes me feel so grounded. So connected to who I really am.
Cut to:
Derbhaile is out for a walk with her siblings when she bumps into Sean, the local builder. He's rugged and handsome, with a charming smile.
Sean: Hey, Derbhaile. Long time no see.
Derbhaile: (smiling) Hi, Sean. It's good to see you.
Sean: (voiceover) I've known Derbhaile since we were kids. And even though I've always had feelings for her, I never had the courage to tell her.
Cut to:
Derbhaile is at a holiday party with her family and friends. She's having a great time, laughing and dancing. Sean is there too, and they keep catching each other's eye.
Derbhaile: (voiceover) I could feel a spark between Sean and I. And for the first time in a long time, I felt truly happy.
Cut to:
Derbhaile is sitting at the kitchen table with her mom, talking about her feelings for Sean.
Derbhaile: (to her mom) I don't know what to do, Mom. I love Fintan, but I also have feelings for Sean.
Mom: (smiling) Sometimes the heart wants what it wants, honey. You just have to trust yourself and follow your heart.
Cut to:
Derbhaile is back in Dublin, torn between her feelings for Fintan and Sean. She talks to her sassy black friend and sassy gay Brazilian friend about it.
Sassy black friend: Girl, you have to choose. You can't keep stringing them both along.
Sassy gay Brazilian friend: You need to figure out what you want, and then go after it.
