I don't think it'd be overly self-indulgent at all! Sometimes you just gotta get the fic idea out there and ramble about it, so that it's out in the world whether or not it actually gets written into a coherent fic. Talking about What If The OTP Did This is one of the best parts of fandom!

I feel that, though. Sometimes I get like "This is a journal, it should have FIC and COHERENT WRITING" and all I really want to do is just...ramble about an OC for three thousand words, no plot.

Sorry it's a bit of a rough day on the enjoying-things front!
