Masumi is raising her son Takashi while working as a so-called "poster" who distributes flyers to mailboxes. There are various types of leaflets to be distributed, and recently, leaflets for adult videos have been distributed more often. One day in the middle of summer, while wiping away the sweat while working, a resident of an apartment building complained, "The product I ordered is different from the flyer." Moreover, complaints alone are not enough, and the sweaty and purely estrus resident remains as it is.
