I love Tywin/Joanna, and there's barely any fic about them at all.

I know! I find Tywin so completely fascinating, and part of what's so interesting about him is hearing how head-over-heels in love he was with his wife; that very fact seems to contradict everything we know about him as a character, but there it is. Such a great starting point for a fanfic writer.

Thank you for your lovely comment- I was a bit nervous about writing these two, so I'm so glad you liked it!
