Following an exhausting day of work, Masamune Hanazawa desires to indulge in a homemade meal as opposed to the usual selection of convenience store food. To fulfill this craving, he enlists the aid of a housekeeping service which dispatches Natsuki Mikoshiba, a college student holding down a part-time job, to his abode. At first, Natsuki appears to be on her guard, but Masamune is exhilarated by the delectable dishes she expertly prepares. Nonetheless, Masamune is shocked when Natsuki unexpectedly reveals her love for him, insisting that it was "love at first sight."
