How does everyone come up with scenarios? Tv? Real life events? Things you see in the neighborhood?
Honestly, I tend to draw inspiration from other stories, whether they're in fanfics, books, TV shows, or movies. I try not to copy other people's ideas, but a lot of my stories started off as a twist on something I'd read or seen.
Sometimes I just start with a genre or a type of story I'd like to write and see if I can come up with an idea for it.
Once I get the premise for the story figured out, I use more real life inspiration for the smaller scenarios, settings, and characters within the story.
