It was good until chapter 18. It's like she is a different person.... One that is not very smart!

Well, she is a world where she knows nothing about, mistakes can happen here and there. Sure it'll be annoying but... Can you really blame her? This isn't a novel or a game she transmigrated into. The only thing she has is the partial memories of the original owner and the rumors about her old self from other people. That is literally it. She is going to make mistakes. It would be nice to have a little more common sense but I wouldn't outrightly call her not very smart.

I feel bad for the older son. I think if he was raised differently, he would have not turned out like this. I think the bad guy here is the father. I honestly hope that things turn around for him and he becomes a better person.
