Floria is the daughter of an impoverished baronial family. Her simple yet peaceful life was drastically altered by a divine oracle. This oracle led to Floria's younger sister, Renata, being chosen as a Saintess. The shy and timid Renata underwent a complete personality change after being chosen as the Saintess, and for some reason, began to treat Floria as her sworn enemy. The numerous harassments from Renata, who had gained power as the Saintess, threaten Floria's peace.

Unable to bear witness to this, her brother arranged for Floria to be sent to a certain noble's mansion, where she would work as a maid. This was because Renata's wicked influence could not reach that mansion. However, there Floria met an exceptionally handsome duke. He shows interest in Floria, who manages to maintain her composure in the presence of his formidable beauty that captivates all women. With this encounter, Floria's daily life begins to change even more dramatically and vividly.
