I believe that the sister is badly written. I think the author wanted to be controversial and go the Classism is good, democracy bad route... however, I believe said author has no knowledge of history and the post monarchy era we live in and enjoy. Long gone are the days where we arent allowed to wear a certain color or risk beheading, or us going to war on the whims of monarchs and tyrants, all cosy in their palaces. Long gone are the days where only the words of posh sons and daughters matter while kingdoms starve. What I want to say at the end of the day, it is quite weird and naive to promote classism through the MC while writing a shallow, idiotic sister as the leader for peasant class. Weird because in reality things would have been quite different in a world where monarchy is almost just a fairy tale. Even existing monarchies have become constitutional ones with their own government and countries that still have tyrants with absolute power arent doing well. Because one thing about classism is that... The ones at the top abuse absolute power. Its funny because this manga is ignorantly dissing the demand for equality while enjoying the fruits of globalisation today brought about by the people that overthrew the monarchy.

the family doesn't deserve the mc, she's a noble, she does her responsibilities in the house and make sure she doesn't let down people's expectations of her. Meanwhile, her sister going round doing shit with a false sense of justice. I was so happy when she got married. She don't need them in her life.
I can't help but hate her family, especially her sister. If she wants to be such a hero than she should educate herself with her privileges to help the commoners like she wants to. Her parents are too much, how do you let your second daughter who is basically only good for making a big mess have whatever she likes and never defend the daughter that's helped you so much. And it's pretty weird the level at which the rumors about her have become, I feel like someone is purposely doing it targeting her. Well to conclude, I want everyone to see just how amazing she is and just how stupid and hypocritical the little sister is. She was throwing a fit over an arranged marriage but didn't care if her sister was sent instead. Ugh !
