Throughout her life, Yuki has been trained and used as a ruthless assassin.
But after several years, she receives orders to go to the house of Hitoyoshi, a young messy boy who lives alone.
Hearing the doorbell, Hitoyoshi goes down to open the door and sees a young woman dressed as a maid asking him for a job. Not knowing what to do, he invites her in.
Amidst bags of garbage, Hitoyoshi hears Yuki’s request, and when he asks her to show her her skills, the young woman begins an attack on a tree in the garden.
Hitoyoshi does not want to know more and tells Yuki that he does not need help at the moment. The young woman says goodbye and leaves part of her outfit behind, so Hitoyoshi chases her.
In a moment of carelessness, Hitoyoshi runs straight towards a vehicle, and upon seeing it, Yuki uses her skills to prevent him from being hit.
Shocked, after being saved, Hitoyoshi decides to hire Yuki, but it’s not long before he realizes that the young woman has no idea what she’s supposed to do as a maid.
To start, Hitoyoshi sends her to take a bath, and when he asks her if she knows how to cook, Yuki tells him no.
Hitoyoshi decides to prepare something to eat, while Yuki tells him that for her, food has no flavor. However, when Hitoyoshi invites her to try a sauce, Yuki immediately falls in love with its flavor.
In the early morning, Hitoyoshi goes down to the kitchen and discovers Yuki, who is still intrigued by the taste of the sauce. Thus, both begin a new stage in their lives, full of learning and a lot of nostalgia.
