Yeah, this is a quality series for more adult tastes. Not adult in an erotic sense but because of the plot and setting.

It strikes quite a nice balance between having a sort of fictional main character in that sort of past-its-prime imperial setting, where everything is too established and the way things are done is far more important than who are doing them or for whose sake they are done. I say fictional main character because obviously Maomao needs to keep getting involved in everything for the story to exist in the first place. Realistically nobody would have such a presence.
