This is a set of three books by Kiriko Nanan, famous for her transparent style. Kiriko Nanan is known to have been influenced by Kyoko Okazaki, but her work "Haruchin" was heavily influenced by Fumiko Kono. "Pumpkin and Mayonnaise" temporarily stopped being reprinted and was difficult to obtain, but thanks to the efforts of Village Vanguard, it was reprinted and later made into a film, becoming her representative work. There haven't been many new works published recently, and this is a collection of short stories that were published sporadically.
