Plot summary
On the request of the military, Violet is sent to the kingdom of Drossel in order to write a public love letter for its teenage 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 Princess Charlotte being anxious about the wedding, Violet writes the love letter, and Prince Damian writes a letter back in response, but Princess Charlotte does not appear satisfied with it.
Princess Charlotte later confides in Violet that she met and grew infatuated with Prince Damian when she first met him since he treated her as a person and not a potential wife or a mere queen consort. However, she is unsure of whether Prince 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 Princess Charlotte and Prince Damian both 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 Prince 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.
