Oono Fumi takes on the role of housekeeper for a young writer named Kibikino-san, who specializes in historical fiction. Initially, Kibikino-san comes across as rude and vulgar, but later, when Fumis motives for becoming a housekeeper become clearer, his attitude shifts. In an effort to make her feel more at ease, he gives up his bedroom to her, allowing her to stay in a larger space within the apartment. Kibikino-san is highly passionate and committed to his writing, often sacrificing sleep and food while working. His background remains largely unknown.
