No need to worry, you won't be reading this again... the scanlation team dropped this manhwa, and we can't change the mindset of the author on how she created her characters, I totally respect your opinion, I'm sorry, I am just sad, and this is one of my favorites already...
I’m sad too, she probably wrote this character this way because she wanted to make her grow as a person as she stays in that world longer. It’s just an opinion on how she is now, as I’ve said it’s still really early in the series and there’s a lot of room to see her growth, although I don’t think we’ll be seeing it in the near future as it’s been dropped.
As much as I like this FL she is a tiny bit annoying in that she’s trying to force her previous worlds values into a parallel world where all that poison training and stuff is a necessity. I completely get how she feels about a child being treated that way but she’s read the book it’s not like she doesn’t now how the Story goes, and she can’t say she knows Ain better than the Duke because she only been there for a short while and can’t remember anything from her previous memories as a duchess, like she literally couldn’t even remember that Ain couldn’t eat peaches and here she is talking about what’s good and not good for him. And saying ‘love’ will change him is so ridiculous like yea you will change him but can love cure poison lady?? Can love defeat all the other nobles plotting to take the family down??? And I read this in another comment but I agree when they said that she doesn’t love Ain but she loves the idea of what she wants him to be. But it’s still early in the series so I hope she has some character development.
