Due to family troubles, Ren Uesugi and his sister, Mihato, leave their
home. They end up moving to the city but find themselves with a lack of
money. Somehow they are able to find work in the form of the Kuonji
family's mansion, being employed as servants to the three sisters of the
Kuonji family: Shinra, Miyu, and Yume. Being a servant also associates
Ren with the mansion's additional servants and the Kuonji sisters'
friends.
