Chiaki quits as a babysitter due to being an omega and works for a housekeeping service company. At the end of the year, Chiaki is suddenly dispatched to an alpha's home with children, and he meets a seven-year-old, a six-year-old, a two-year-old, and the hybrid alpha Oogami. The gray-brown wolf has the worst personality ever! Although he started living while taking care of Oogami, after a certain night, a strange feeling overcomes Chiaki's body?!
