It was the emperor who summoned her, he probably doing it to brag in her face that he’s having a child that will replace her 3 kids from the throne and or ‘ask’ her to be a doula for the empress since she has ‘experience’ and if anything goes wrong he can easily blame her.
And probably a way to also poke fun at her like he did to the MC by offering her a position lower then what a princess and a grand duchess is supposed to get.
Sorry for the comment but I hope that birth child cause her death or her child, or at least make that child weak to the point that his not qualified to have that fucking throne'~
Try to be so high and mighty, even though that position was just passed on to him by his sister who is much more qualified for that position'~

She's not a lady in waiting. She's not from the empress faction. She's not the empress friend. She has no reason to go there. Author-san did you do any research on this aristocracy crap?
