Dressmaker Lena Schneider, a rising star among the nobility’s clientele, reluctantly agrees to an arranged meeting for marriage with Count Elias’ son. To her shock, she finds the fiancé to be 15 years old, a minor—and discovers that the meeting was a mere facade for a “selling of two siblings” by their adoptive parents. In order to protect the younger siblings she once helped, Lena enters into a contract marriage with Elias, intending to care for the kids until they reach adulthood—then seek divorce. But as their arrangement deepens, unexpected emotions, protection, and commitment arise. Lena must navigate the aristocratic dangers, her own choices, and the siblings’ unfolding lives.
