The story is about a young girl, Aoi, from a family who elevated into noble rank from being commoners due to the success of their merchant business. As the Aoi attempts to become a proper lady, she's accompanied by her servant, Reiichirou, whose from a fallen noble family. So far, it's a very cute story. The relationship between Aoi and Reiichirou is basically the same as so many other shoujo mangas with similar settings, but I'm still eager to read it regardless.
