Really the characterization of the protagonist is really poor:
"Before I was bad but now that I'm Isekaied I'm not bad"
Okay, but who are you? Where does the bad mother come from? what she was doing before? and above all why did she get married if she didn't want to deal with his family and why she was going to bully the boy?
and even father and son, who seem more clones, are not exempt from this problem. Yes, there are small details here and there that can suggest things but they are always a mess of questions and in 11 chapters it is not that the author has given us the answer to at least one of these
Who are these 2 oxygenated blondes?
What does the father really do to live? (kills spies yes ok, but what do they want ?, a 10-15 year old boy with a poison fix and a nascent oedipus complex?)
Ok they are "falling in love" with the chick (I expect a good fight between father and son for his attentions) there is the spoiler already in chapter 0, (which honestly could not have existed) but before that... why did he get married? I doubt big blondy wanted to give a mother to his son, certainly he didn't marry her for love or because he wanted to do sex with a beautiful (and probably a little bitch) woman, he seems the classic type only in love with his job(which apparently consists in torturing people). I suppose for political reasons but they should be at least important, to explore the protagonist's past and how others see her BEFORE her change. It is not enough for me "before she was a bad person", above all in a product that explores the idea that it is an individual's previous history that makes him evil.
I don't know, I would like them to devote a little more to the evolution of the protagonist herself and not things like "ah she's no longer afraid of him for the sake of her son" because apparently not even the original version was scared! Everyone is amazed that she wants to be a good mother, but nobody seems to be surprised enough that suddenly she is no longer a bitch.
... What am I complaining about?! it is the same problem in all isekai
