@Mivas: i know it's not entirely the MC's fault, she also has part of it but people are blaming the father for everything despite all the misunderstandings that have been shown. I guess it would be also a misunderstanding from her side that her father has never showed her his love for her, in the crown prince's flashback, the duke always talked about his daughter, he only has had a soft side when it was related to her, etc... And we can see in all the released chapters that he really cared for her and showed it quite often in his own way, if he is like this now then there's no way he wouldn't be the same in the past, even the servants knew yet she misunderstood every of his moves and felt unloved and lonely all by herself, she has not even trying to confirm anything: whether her dad really hated her or not, whether Mikhail loved her or not, whether the sword given to her was for suicidal, whether the crown prince came to torture her or not. It's just simple questions: "Father, do you hate me?", "Mikhail, i love you, do you love me?", "Father, is this to kill myself?", "You came to kill me?"
This chick is quite passive in what she should do, and too aggressive in what she shouldn't do.
