hii!! I really like this question lol. Normally, when I'll decide to write a fic, I'll have a general sense of how I want it to end, maybe a vague idea of a scene to finish it off or something like that. I'd like to say that as I am writing it, I decide exactly how it'll end, though my initial idea might change anyway. Usually I deem a fic good enough for posting after I've read it over several times/checked for spelling mistakes/ edited scenes I'm not completely happy with, although I've had the misfortune of encountering little fuck-ups long after I've posted fics but yk....at least the mistakes are my own😭
