The story is based on the life of fashion designer Koshino Ayako, who passed away in 2006 at the age of 92. Although she was a successful designer in Japan, she also single-handedly raised three daughters who followed in her footsteps to become internationally known designers, named Hiroko, Junko, and Michiko. Ono's character in the drama, modeled after Koshino, is named Ohara Itoko. She will play the character from her teenage years to her fifties. The story is set in the Kansai region, but Ono will have no problem with the dialect since she is originally from Nara.
