Kashoku Enbu Shushu

Princess Shushu has an overwhelming love for her people. In the country of Fuu where she is to be the ruler, tradition requires that the country be only ruled by a married couple, but because of this, Shu Shu has never been able to find a husband! Shushu sets off on a journey to find a husband in another country, but will she be able to get the husband she desires at the end of it?
