This is a terrible series. The FL is arrogant and a mary sue. She seems to be rude for no apparent reason. She gets away with being rude to other people because she's pretty? This is different from the villainess trope where there's a reason why they act mean. She's portrayed as this beautiful woman whose outspoken attitude should be charming but it's just done sloppily. She's rude to the prince for no apparent reason. He also doesn't like the arranged marriage but at least he tried to be polite in their first few meetings until she flat out told him to get away from her? Really? THIS is who we're trying to believe is a princess?
She and the prince don't even try to give this arranged marriage a decent chance. They're just spoiled bratty people who don't even try to act dignified. Then again, they're 16. But still, it's just annoying reading about this. Some of the stereotypical western webtoons are also pretty cringy sometimes but at least you see characters who are actually people you can symphatize with.
