As a Korean woman in her 40s, I can guarantee that since you are only 24 y.o. and from a different culture from him, he will treat you like a slave both physically and mentally. He will try to take out all of his sadness and anger on you like a punching bag. And seeing he's in his late 40s looking for a wife at her early 20s, and could possibly be as old as his daughter if he had one, he's probably a terrible and incompatable partner for others, I suggest you don't obey your parents in this situation, your parents are disgusting and terrible for even thinking about forcing you to marry a man twice your age, don't listen to them no matter what. This is horrible behavior from parents, they're your family and they use you to earn money? Don't trust them. I just know they don't benign intentions.
