I decided to let Akechi and Akira reach rank 10 on December 10 because it would mark the full 6 months of them having started their relationship on June 10. Ann was the only thief to really check on him before the fight with the Cleaner, which I never noticed before. Coincidentally, it rained that night after Akira got back from the Palace, and the following day, seeing this dialogue from Sumi felt appropriate.
