[Nice work, Nina! Her light touch gives Hijikata confidence that the mission was successful. Of course he can't acknowledge her, instead walking up to the street to wait for the carriage with his "workmate" (who seems to really have liked the cake, going by his inquiry for the bakery Hijikata got it at).

It's hours later that Nina receives a text message from him, asking her to meet him "at the usual place" in the evening. Once again, he reserved the same room at the Shinrin-Yoku, and when she arrives to tea and snacks he looks preemptively pleased, like the cat that got the cream.]

I'm going to assume that you pulled it off! At least nobody noticed you, that's half the battle won. Now the photos just need to have come out well.
