Mio Omori's father died when she was young, and her mother has been hospitalized for some time with an unspecified illness.
One night, when going home after work, she encounters upon a violent young man who throws money at her, saying he'll 'buy her', after stealing her first kiss.
The next day her mother tells Mio that their landlord, who happens to be among her father's closest friends, has offered her a job as a maid at their mansion.
[10] AnimeLand regarded the first volume's story as 'sordid', disliking the non-consensual relationship that Mio is in, but noting that the author is popular with Japanese girls, "who do not seem affronted by the scenes of domination by horny males".
[11] Faustine Lillaz, writing for Planète BD, "gained the impression of a modernized Cinderella", but found the actions of the male characters to be "very caricatured".
