Revenge Wedding
the ML is the strongest soldier meanwhile the FL is the most beautiful but also the most blunt women in the kingdom meaning she doesn't get any marriage proposals. So her dad is forcing them to get married, and to make sure they don't escape they hold the wedding in the middle of the sea. They get married and get knocked out. when the open their eyes again they are in a secluded island where they have a honeymoon. but they find out the have to do everything themselves like finding food and other essentials since the boat that took them there only had a limited supply. they did not get along at all but near the end they start liking eachother. When they finally escape they get married for real. I like it since its kind of a enemies to lovers trope.
