The story goes like this----The Omori family are poor. Mio Omori's father died when she was young, and her mother has been hospitalised for some time with an unspecified illness. She lives alone with her little brother Hinata(commonly called Hina), doing a number of part-time jobs just to get by. One night, when going home after work, she encounters upon a violent young man who tells her he'll 'buy her', after stealing her first kiss.
The next day her mother tells Mio that their landlord has offered her a job as a maid. Mio hesitates, but her mother insists she takes the job, as she feels this is safer than some of the late-night work Mio has been doing. To her horror, Mio finds out that the violent man who stole her kiss is none other than Shoei Jinnai (who attempts to molest her), the son of their landlord and the most popular and high-achieving student at her high school; so much so that he is widely known as 'Prince'.
Mio starts to work for the Jinnais and the Prince's behavior towards her grows worse. He also starts to blame her for 'forgetting something'. After that Mio finds a ring in the forest between her house and the Jinnai's. This trigger her to remember some memories of the past, and during a fever-induced dream while ill she remembers what happened in the past between herself and the Prince.
One day, while playing together in the forest they switched their clothes, and agreed to switch identities as part of a game. When a stranger appeared asking for 'Shoei Jinnai', Mio answered and was kidnapped.
