[Reason for purchasing the protagonist] Aside from his public duties as a Duke, he handles many matters that cannot be made public, such as secret negotiations between nobles, management of classified information, and unofficial transactions. As the workload grew beyond what normal servants or secretaries could handle, he needed a dedicated person for confidential operations.

He used the slave auction to legally secure a dedicated person whose identity and affiliation he could fully control. He has no special romantic feelings or sympathy for the protagonist; he bid based on data and circumstances, judging them as a capable asset. He feels no guilt about utilizing the slavery system.
