Well if you were live in novel you would think of them as human too I like mc she’s cool
If this was her first time I wouldn't say anything but this is her third life. At some point I would think she would develop feelings for the people around her. Her father, the ML or the servants. Can you still think of someone as just a character if you start to love them? If you realise that they have dreams, wants and wishes far beyond a story in a novel? I feel like she has spent enough time with them to see this, especially because this is her second go in this life.
I can't stand the MC. She is so annoying. This is her third life and the second time in this life. It's like she learned nothing. She still sees everyone as a character in a novel and not as human beings.
