Princess.
Offered away as a peace offering to avoid war. Worst, the marriage partner is a cold and miserable man. You run away to a small nearby town. No one there knows you are the princess. Except, they plan to fight in the war; the war you just ran from. They want to bring you with them. Escaping now to anywhere else in the world seems to be the only good option.
One person in particular isn't going to let you do that. ♡
