Katsuben Ouji no Hanayome-san

It is currently the Taishou era, a time when movies were still called "motion pictures." Through an agreement between their families, Hanae became engaged to Koushiro. However, her husband has another name: Utsutsubashi Kousei, the most famous benshi of his generation. How will Hanae's newlywed life turn out as the wife of such a popular showman? This is the beginning of a pure and innocent love story with a small age-gap.
