Hana, a big-breasted wife who works full-time part-time five days a week with her husband, was secretly summoned to public restrooms by a middle-aged man called the 'manager' after work. Lured by words like 'I think I can arrange a raise for you, Hana...', she is raped repeatedly in the station toilet. Her husband, oblivious, simply rejoices at his wife's raise, but Hana gradually falls both physically and mentally from the daily acts.
