On the request of the military, Violet is sent to the kingdom of Drossel in order to write a public love letter for its princess, Charlotte, to Damian, the prince of the neighboring kingdom of Flugel. Violet's mission is crucial since Drossel and Flugel were previously enemies in the war and are arranging the marriage to cement the terms of the peace treaty. Despite Charlotte being anxious about the wedding, Violet writes the love letter, and Damian writes a letter back in response, but Charlotte does not appear satisfied with it. Charlotte later confides in Violet that she met and grew infatuated with Damian when she first met him, since he treated her as a person and not a potential wife. However, she's unsure of whether Damian reciprocates her feelings or not, since she could tell the letter he returned contained no emotion in it. Violet then gets an idea and arranges with Damian's doll to have Charlotte and Damian write their own letters to each other. This starts a heated but passionate correspondence between the two that entrances everybody in both kingdoms. The wedding goes as planned while Violet and Cattleya, who was Damian's doll, return to Leiden, though Cattleya notices Violet smiling. Upon returning, Violet encounters Gilbert's brother Dietfried, who expresses disbelief at how she became a doll and reminding her she had killed countless people, including many of his men.
