@angellordemon funny how you say that considering you have the avatar of the FMC of Revenge Wedding.
Also I get the feeling that the ML of this story already knows that she's the one he was looking for.
I am surprised she doesn't just have a prenup written up saying that the groom has no claim to the business or will have to give up everything in the divorce.
I doubt the heroes would treat him better. They would use him as a weapon and when he gets depressed about hurting those he used to care about, I can see them ditching him.
I can think of a few reason it is rated high. It has good art, a romance that actually progresses instead of repeating the same clichés every episode, characters that have the potential of being quirky, characters are not brainless, and doesn't have annoying misunderstandings driving the plot...
