What kind of GF Fanfiction should I write?

Quarantine has got me bored. I'm in the mood for writing a short fanfic. I want to write a more serious-based, yet still comedic form of a fanfiction. Something to grab people's attention when I post it. Of course, I don't have the talent to be able to do something so clever and immersive, but I'll try it out anyways.

I'm free to suggestions or specific details in the comments.

You're technically giving me a writing prompt lmao.

I honestly don't know if I'll ever finish this, but I do know I will start on it somehow lmao.
