Daisuke Kaji doesn't find typical girls appealing since he views them as impolite and inconsiderate. Specifically, he avoids Chiriko Iega, who he deems the least polished girl in their school.
Due to his father's debts, Daisuke must leave his apartment and live with his father's pal's daughter-who just so happens to be Chiriko. Living with a girl is a shock for Daisuke, but the state of Chiriko's home is even more unexpected, as it's full of junk and filth because Chiriko neglects to clean. Luckily, Daisuke is skilled in cleaning and knowledgeable in using chemicals and speedy cleaning methods.
Despite his initial reluctance, Daisuke caves to Chiriko's insistence that they clean her house so they can avoid living in a dump. As they work on this colossal task, their bond grows stronger and the house becomes more habitable.
