Houtou Musuko to Sewagakari

A young man from a wealthy background, Eiji, has spent most of his time as a student enjoying a carefree lifestyle filled with social activities and relationships. After his father, Eiichiro, discovers his poor academic performance, he is sent back to the family home to prepare for taking over the business. To assist in this process, a personal servant named Izumi is assigned to him. However, Eiji quickly notices that despite Izumi's polite demeanor, there appears to be little to no respect or approval for him as a master.
