When I said at least two. You know how that looks like a blatant slip you didn't process my words. Stories layer elements, and in situations like this they should layer a small set that enhances themes.
It's not about writing or characters' emotions, it's simply about the character getting punished for their wrongdoings.
Like, what matters most is that good guys get rewarded and bad guys get properly punished, not that the intricacies of human relationships are explored in any meaningful way.

You're mind-reading about others intentions and goals to infer that it undermines their argument (one word for it is bulverism). Their feels or desires doesn't de facto make them wrong or unable to see a dramatic element you missed. This is a case where it's more fair to say that the desire for the universe to make sense is part of appeal of stories. Stories also can make use of the meaninglessness to highlight details. Any of that can layer, freeform, to meaningfully lay out intricacies of human relationships. There are plenty of options. Baggage around parents may touch off emotion but we're thousands years into that being part of good plots.
You were dismissive about how others viewed a plot gap, and list sweeping assumptions as if reason not to consider the criticism.
The presentation so far is flat, we don't even disagree there. Nor about the more important plot thread which was not the topic at hand. Your thoughts unrelated to others is totally fine, good chat.
I don't expect much, the point on the author's strengths is fair and she hasn't had much delicate toxicity in her
serialized manga afair, but I doubt it's beyond her skillset to land the mom plotline. I'll stay open to whatever her creative priorities turn out to be. Alternatively, this could be a sign the manga got cut short from plans but I'm skeptical of that for now.
