She doesn't want resentment or revenge, she just wants to live a normal life like a normal person, but such a small wish has become a luxury for her. She is like a plaything in the hands of the devil. She finally escaped from the prison, but when she was happy, she found that she had entered another bigger prison... In this case, why should she stick to the boundaries of a human being? She is a monster anyway, isn't she?
