First of all, the ones who should be outside are guards. Even if there was a maid, the guards should still be there. Having said that, supposed maid would act like a guard, standing there in wait. On the other hand, as u said, that maid in the manga was roaming around. Even if she was supposedly getting a job done, you can't just go there throught the corridor where the lord is sleeping.
Idk. Personally I don’t see it like that. She is Rin’s head maid so she could be there to like check in on her or in case she needed something. The one about guards is true idk why there aren’t any. But personally I don’t see a problem with head maid being around her lady’s room, after all she is in charged of that room and taking care of that person
I mean, i also think she should have guards...i thought i had said that already. But that's besides the point. I was emphasizing on the lord being there bcuz his status is more important, hence why it is more imperative for there to be guards. And yeh, they do seem chill about it and that's why we were discussing it, bcuz it doesn't seem alright since manga castles and such don't normally work like that.
Idk but how could that maid even b outside the lord's room at nighttime .-.
