I get it, you have your own grudge for your safety, but honey sweetcakes the prophecy is somehow changed and your majesty did too. He didn't disregard her like in the book so of course he's now worried for her and treated her as his own. She took care of him, helped in his alcoholism, and even provided to the kingdom so please open your eyes and heart.
I love this story so much that I can't wait to see their love child >< Oh well I'll back after a few months again adios~
