Boy meets girl and has hot sex then messes up, and he loses girl, then they make up and have hot sex then he messes up again and loses girl, and that goes on for another time or two until boy and girl realize they're meant to be and team up against boy's asshole brother.

The boy in this scenario is a step-prince of a fictional Danish-speaking country, and the woman is in HR at an academy that kind of sucks, pedagogically, so she's not super committed and goes along with it when the boy announces their (fake) engagement. There's money in it for her and her sick sister, so that helps.

It's an okay read, maybe a little long. Much sex and healthy domination.
