Yoshitaka Nakabayashi inherited a large sum of money after his parents passed away in an accident. As a 14-year-old millionaire, he required assistance to manage his daily life and hired live-in maids for this purpose. Two runaway girls, Izumi Sawatari and her younger sister Mitsuki, stumbled upon Nakabayashi's mansion and were immediately employed by him. Although Nakabayashi is not only wealthy but also a pervert with uniform fetishes, he wants to be addressed as goshujin-sama (master). With nowhere else to go, Izumi reluctantly accepted the job. Additionally, Mitsuki's pet alligator Pochi had no other place to reside and was welcomed into Nakabayashi's home.
Kore ga Watashi no Goshujinsama was published in English as He is My Master by Seven Seas Entertainment from July 24, 2007 to February 3, 2009.
