The only case where she really got completely dumbed down is during the engagement incident, needed to put them into this political situation.
The other recent cases, it's just result of how Rosemary respond back, while Serena avoids.
Which put them into the situation where Serena seems to be sidelined.
But Rosemary is a hateable character, and that makes Amaryllis who had been spoiling her also seen as enemy.
Efforts?? Dude, she's her child. It's also a responsibility for a mother to her child to teach or at least be a companion, the mother literally sideline serena. Serena mother is a bad mother, that is a fact. Or if that kind of mother is your image of mother, then i have no say in that.
I really just want the society here to start accept it's not something that can be fixed with her "doing the right thing" (whatever it is the crowds think will work, or she will need to keep repeating until it works).
I think what Abricomas was trying to do is see her as a human first, not just as a (have to be) perfect being called "mother" as everyone is pushing.
She tried, but hit a wall. Rather than trying to sympathize and understand her situation before acting like they know the proper way to do it, it seems like everyone just want to punch her face with saying it's her punishment for having given birth to a child. A society who is not interested in listening to reason (they think is just lame excuses) and only want to see the matter fixed. Which is not helping, really.
That kind of society will just make a person hate her own life and regret having a child rather thinking of any constructive solution.
For Alto... the manga version really changed it with hinting Serena warming up to him. While in the novel, she is thinking about killing him if he got too close to finding out about her real identity. Meanwhile, Alto already know she works as an assassin but let her because he saw her peculiar personality as a strength to be given room for growing, rather than as mistake to fix.
