A servant to an important metropolitan nobleman accidentally learns a secret about the king’s heir’s birth—after which a chain of misfortunes falls on her: kidnapping, slavery, humiliation. Hiding from her pursuers, Swan begins to think more and more often about why Prince Erii, having left state affairs, follows the trail of an ordinary maid. His actions confuse Swan, and she can’t understand what drives the heir: the desire to bury the secret she knows—or love for her, an orphan who doesn’t know her origins.
