A flash fiction is a genre of fiction that can be defined as a very short story, but even if it’s a really short story, there are still plot and character development in the works. A one-shot story is also a short story, but is only done in one… well, shot. So, like, see a one page/ chapter or something-
A flash fiction is not necessarily one-shot, but a one-shot can be a flash fiction… or at least that’s what I think.
I’ve read one shot stories before, though I’ve only ever seen them in Wattpad, so now I’m thinking it’s a Wattpad thing xDD but yeah, I do like to read them; they’re short but also intriguing.
