I sort of want to write a oneshot book of a crap-ton of different fandoms but then whenever I try I begin to add WAY too much backstory, random details, side plots etc. And I don't want to write a story with plot holes or that's like a novel but only one part so basically I'll just stick with attempting to write a full fic.
(This is why Blue Neighbourhood is only 3 short chapters because I also cut out all the extra bits)
