Love this! And love this pairing! You really captured both characters well, please update soon!

Great story. I think you've caught Missy's and the Doctor's characters really well. Although it would be great to learn more about their backstory on Gallifray, I really enjoy her mentioning the Valiant. I loved Simm's Master asking the Doctor: "Are you asking me out on a date?" Their story has so many interesting twists and turns...Missy is just the newest.
