Agree with you..
Growing up, I kinda find it difficult to explain to others about my family dynamic. People around me, either have a complete, harmonious, full of love kind family or a broken one (like parents committing adultery or abusive). While mine, lol, let’s just say I love my family but I don’t wish to live with them. Not even a day.
That’s why I cry so much reading this one because I’ve been there and totally understand where she is coming from..

I really like how they write on the family, I read alot of similar setting the family either kind or abusive on the daughter. But this is just neglects due circumstances in which we see it as abusive but they can consider as a kind parents. If they weren't they wont cry or feel remorse about Karina leaving them. It's just that they fail to understanding the Karina's feelings and compare to the siblings she just doesnt stand out so her existance feels very mild. Even thou the siblings can be mean(teenagers mind) but they definitely doesnt hate Karina.
