At the start, I was pissed at her --->
Then it turned into annoyed --->
Then it turned into hate --->
And at the 58th chapter, it just turned into i-pity-you-but-that's-about-it
because of her taste in men

Pissed is more of a mild version of annoyed. If I'm pissed at someone, it's more of a temporary thing and it can easily go away if that person does something good.
But once I'm annoyed at her, it'll stay that way no matter what she does. Like when she backed off from the case of her uncle- she was still annoying.

A culture where you kidnap women to be your brides........ Wow....

I wish it’s not real tbh and I truly feel sad for the victims. Here https://youtu.be/l-Wl6zbrat0 is one of the occurrence. You could tell how dreadful it is( ̄へ ̄)

it's not as if she wants to act like a kid, she just can't help it.
She was an adult in her past life, but since she's a kid and everyone treats her like so, she'll unconsciously identify herself as a kid and therefore act like a kid.
It's like the Stanford prison experiment (or the psychological prison experiment if the name's wrong) where the guards (that were just normal civilians that were given the title 'guard') became too engrossed in their roles that they soon identified themselves as guards. Same thing with the prisoners.
^ if you're too engrossed in the role you were given (plus adding external factors such as your environment) you will unconsciously take on that role and act like it. It's like second nature to her to act like a child despite being an adult.
And there ends my TedTalk. Kudos to whoever finishes this.
