Shinobu, who works in the advertising department of the female underwear maker Princess Underwear, has a dream of becoming a fairy tale writer. He has a colleague and fiancé Taeko, but he promised that he won't get married until he saves up 3 million yen, so until then he continues living in a second-hand bookstore.

One Sunday, Shinobu, who was just walking around the city, helps an old woman who has fallen over. The old woman, Ijuuin Ayano, was born in a noble family and had run away from Kyoto due to a disagreement with her daughter-in-law.
