The background is an unknown medieval era where there are three countries. Among the three countries, there is an island country called "Ramira". The empire, Ramira, is where most of stories will unfold. There are generations of princesses, and the first 27 volumes set the story for the eventual regaining of Ramira by the greatest Empress of Ramira, Preia, who was beloved by the people and had many loyal men under her.

The first 31 volumes are considered Parts 1-4 of the story. A continuation, known as part 5, was released on Naver following the completion of Volume 31. These Part 5 chapters have not been collected into any volume but are listed as volume 32 here for better organization.
