Elise Lars, the daughter of a marquis, is an ordinary person. Her grades are so-so, her personality is gentle, and her family status as a marquis is not very high. What I would like to point out is that her servants are extremely talented and loyal. The Crown Prince tries to make them his closest aides, but when he is in a pinch, he sees a glimpse of Eris's extraordinary nature. What is the true identity of Eris, to whom her twin, the Deputy Director of the Ministry of Magic, and the Mad Dog Butler swear allegiance? ? An unparalleled master-servant love in another world between an ordinary (not) young lady and a perverted butler!
