I really liked the start but it became too positive too fast. I wanted the series to have that sort of depressing tone to it, without any cheating involved. Also isn't the love route way too obvious?
How on earth can MC start to sympathize with her father despite the grudge she held during her entire imprisonment? Yeah maybe he had it rough but that does not excuse the way he treated her and his former wife. He humiliated her, especially in a medieval setting, and left his own daughter alone with what he perceived to be a mad woman. He shamelessly returns after she has passed away and in no point in time does he try to be a real father to her. As a father he should have tried to understand her instead of calling her a spoiled brat
