Thank you for writing something for me and taking the time to look at this letter. My letters always get terribly long - I prefer listing a variety of things I like and hoping that some of it works for you rather than only prompting one or two things you might hate. Obviously I don't expect anyone to include every single thing I've listed in this letter. I've listed some general likes and dislikes - that's the important stuff, really. It's followed by a list of kinks I like reading about, should you feel inclined to write porn, and then fandom-specific sections with a variety of prompts. But if those don't work for you, that's fine - if you write something that includes a couple of elements I like and doesn't include any of my DNWs, I'm sure I will enjoy it.
As a general rule, I enjoy all ratings, I like darker, angstier fic and more light-hearted stories, although neither completely conflictless fluff nor completely bleak darkfic with no ray of hope are quite my thing. I like shorter fics and plotty longfic. I strongly prefer shipfic to gen, but if you don't want to write my ship, I think many of my prompts and likes also work for gen - casefic or background stories about characters' past are always fun to read. As long as there's some focus on the relationship between the characters I've requested, I'm happy, even if it's not a romantic/sexual relationship in your fic. I'd only ask that you don't pair off these characters in other ships I didn't request.
I am in love with every single one of the fandoms I'm requesting and would be happy to receive a fic in any of them. Some fandom-specific sections turned out longer than others, but that's only because I had more prompt ideas for some of them, not because I like any one of them better than the others.
I use the same username on AO3 and tumblr.
