The two were supposed to live happily ever after, embracing their true love... or so they thought.

This is a story about a prince who went completely off the rails due to a misunderstanding, the condemned Duke's daughter, and the perpetually carefree and oblivious Countess's daughter who was the true heroine until the very end.
