The Prince, as Princes often do in these tales, would disguise himself as a commoner and go among his people. And, as often happens, he fell in love, with a beautiful, if unrefined, young lady who worked in an inn. For months the two were madly in love, until The Prince could lie to her no more, and revealed who he was to her. In shock, she laughed and made a joke about wanting him to leave for lying to her. Heartbroken, he left before she could stop him. He never came back.
