Ruby

A girl named Rubin was married off to a prince of a neighboring kingdom to protect her own realm. However, the prince turned out to be cruel and depraved, and their marriage was far from a fairy-tale happiness. To escape, Rubin is forced to pretend to be a lady-in-waiting in a foreign kingdom. She becomes a target for the unclean—and only a mysterious warrior from elsewhere offers her protection, bearing a dangerous gift. Princesses are warned to beware of someone like him, but Rubin didn’t know she should fear not the warrior, but the consequences of their meeting—and the feelings that could be more dangerous even than death.
