Horigo, a single man living alone in an apartment in the third district, has recently been troubled by a mysterious rumor spreading through town. The rumor, whispered among the men in the neighborhood, is crude and salacious—Mrs. Haga, the wife of the most beautiful household in the third district, will sleep with anyone who approaches her. Said to be a secretly depraved woman known only to a select few, the gossip deeply intrigues Horigo, stirring his curiosity and drawing him closer to her.
