Her father wouldn't have forced her into this marriage. He loves his daughter too much for that. She's just so dense that she never thought of talking about it with him, and that's how she got to where she is today. Her father did the engagement with the crown prince, because he thought that his niveau would be high enough to kinda deserve his daughter.
And if they had met at least once in their childhood, they would so deeply in love by now and engaged since the early days, because it was love at first sight for both of them.
