MC praised herself in implicit ways as a magnanimous and wise young duchess who loved her people but sometimes, she also could be apathetic towards others. She only listened to something that she deemed interesting or important and didn't bother with anything else. But how could she become a wise ruler without listening indiscriminately? What she deemed as unimportant was maybe important for other people so she shouldn't determine whether it's important or not by her own interest.

Meanwhile, ML was actually a smart guy but he was a horrible ruler. He immersed himself with dragons and didn't bother to improve his poor territory. He also spent his money on dragon's maintenance until his new bride, MC, was forced to be a vegetarian. Thankfully, MC was a capable woman and had many ideas to help him managing his territory.

Another unlikable character was the duke aka MC's father. He was weak and couldn't even stand up for his own daughter. It's later revealed that MC's marriage with ML was his own idea because ML was his friend's son. But still, he should at least try to prove MC's innocence first before sending her away. How could he let MC have a bad reputation among aristocrats? And if he took his time to investigate, he would come to know that it's all Charlotte's doing so he wouldn't be so amicable towards her who he considered as his 4th daughter. He also shoud tell MC about his thought about her marriage with ML so she wouldn't leave in sorrow.

Aside from the duke, the king was also a horrible character. MC mentioned that he was a good ruler but if he was like that, how could he punish MC without any proper trial? Before listening to MC's testimony, he directly gave her a verdict. Really such as "wise" ruler.

Aside from being an expensive pet and a mean of transportation, they didn't have any other use. Really such a waste.
