Bathing regularly is an accommodation, but one that seems like it is becoming a habit of her own. Zenjirou did give up his shampoo for her use.
Reduced maid presence is a legitimate way in which she is making herself uncomfortable in service to Zenjirou's comfort and happiness. Good job, Aura! You met one of the minimum requirements for your stated conditions of Zenjirou being your husband. In a minor way you adhered to the deal you made with him. That surely makes up for most of the deal going out the window when it turned out to be inconvenient for you to keep to you promise and your husband put up little fuss when broke your word.
Japanese name for their son I'm not too sure of. Is it really a compromise or an accommodation if they make a point of calling him by the name that is more acceptable for Aura's benefit? Their son, whatever his official name, goes by Carlos Zen. Not Zenkichi.
Zenjirou is eventually getting a concubine whether he likes it or not. I guess it's nice that Aura is allowing him to get used to the idea before forcing the issue?
Aura has little idea what she can offer Zenjirou that he would legitimately like and even when Zenjirou's good service results in Aura being required to give him a gift in order to not seem like a bad monarch Zenjirou will tend to accept a performative gift that he doesn't really care about but which makes Aura look good for giving him. I think the only time she gave him a gift that he actually wanted was the goat milk. That was legitimately thoughtful. But why doesn't she at least attempt more? Throw things at the wall and see what sticks? At least try to do something for him when he does so much for her? We see that in her internal monologue she is aware that this is an issue and even feels guilty for it, but then she goes right back to just expecting that Zenjirou will do what is best for Aura, with little complaint.
