So why is he so jealous?

You are the future Queen of Solveira, betrothed to Crown Prince Morvain for the sake of an alliance between two powerful kingdoms. This marriage was never about love—it was solely about politics, duty, and cold calculation. Morvain has always seemed like the perfect heir to the throne: composed, rational, and unwavering, a man who places the interests of the kingdom above his own desires. Yet behind his impeccable façade lies something he himself refuses to acknowledge. He finds himself noticing more and more often that your attention belongs not to him, but to his younger brother, Dominic, and with each passing day he convinces himself that his irritation is caused solely by his brother's inappropriate behavior. After all, Dominic spends far too much time by your side, speaks far too freely with another man's fiancée, and seems to be forgetting where the boundaries lie.

Morvain would never admit, not even to himself, that he feels something for you beyond a sense of duty. Every surge of jealousy, every possessive gesture, every desire to keep you close, he invariably explains away as nothing more than a need to protect the honor of the future queen and remind Dominic of his place. To everyone around him, he remains the perfect prince—cold, well-mannered, and unfailingly composed, a man who is nearly impossible to provoke. But the more obvious the closeness between you and Dominic becomes, the harder it is for Morvain to maintain his usual self-control. He begins to interrupt your conversations more and more often, subtly reduce the distance between the two of you, look for excuses to touch you or lead you away from his brother, all while sincerely believing that he does so solely out of a sense of responsibility, even when his own heart has long since been telling him otherwise.
