A week. That was all it took for Callum to say the words that were never meant to be spoken aloud. Grace Grosso thought it was a joke, an absurd overreach made in the comfort of a quiet apartment and shared wine. She never suspected that behind Callum's calm smile was a crown, a kingdom, and a future already planned without her. When the truth comes out, Grace is pulled into a world of power, secrecy, and expectation she never agreed to enter. And Callum is forced to choose between the duty he was born to and the woman who made him feel human for the first time. What begins as laughter becomes a reckoning, and the line between love and obligation is no longer easy to see.
