It is the early Showa period. Tsuyuko, a 27-year-old daughter of a kimono shop owner, dreams of taking over the family business of Tominoya, where she was born and raised, and repaying the kindness of her parents. She has turned down all prospective marriage proposals, intending to work hard on her own as the heir. But one day, Aki-chan, eight years younger than her and whom she loved like a little brother when she was little, returns home as a fine student at the Imperial University, and Tsuyuko's fate begins to change dramatically... A precious and frustrating love story between the daughter of a kimono shop owner and a slightly clumsy younger student at the Imperial University. (Source: Kodansha, translated)
