I get the criticism

I do get the criticism however I’ll say this. In many ways her want to leave was because of her lack of affection and love at home with her supposed “family”. Yet her choice to stay is to be with her actual family and her love interest. I don’t think there’s a problem either way. I think if our male lead had been more of a black flag I’d say her leaving was the better option. In this case it makes sense to me that she’d stay.
