I don't like their parents. like they barely pay attention to their children

Because they are noble and you only feel that they "neglect" their children because other creators present them as if they were average parents ╮(￣▽￣)╭

I don't care if you're rich enough to have caretakers, even irl rich kids should be able to confide in and feel loved and spend time with their parents. it's not right to not give parental love to children. it actually stunts their emotional growth too

Well as you already claim, you don't care. Then it's your understanding that's too shallow to be able to.understand that people doesn't hold time within their grasps and if they want to have a happy family, parents should put up some effort to do so. It's just happened that their parents are responsible enough to not let their assistants to handle their roles and jobs. It's called "responsibility of the leader" that some duke, duchess, and emperor and empresses in manhwa had been doing and you all find it "romantic".

Of course not all people find it romantic :) I would say the same to you, as your understanding being to shallow. Different people have different views.

And of course, since they’re not average parents and are nobles, is it wrong to say that their way of thinking is not good on a child growing up? You could think in the past, our way of thinking was not good back then so it’s fine to say whatever they’re doing is wrong but justifiable in their time-line but still wrong to not be there ALL that much.
