Exactly like
@Momogi said, this feels like a Chinese webtoon rather than Korean. It seems like the characters don't even have common sense, they're not acting like normal human beings. I don't even get the heroine's reason for "aggravating" the prince. If she's so against it, why not just propose for a divorce herself? The villains seem to be added to make the main characters look good.
I'll rate the story 4/10 and the art 5/10 (the art look somewhat distorted. The heroine and the ML are said to be super beautiful, but I don't really think so?
I rarely drop Korean webtoons, such a shame.
