Every year in this country, a "Lady Ranking" is held, where young ladies are ranked and the most beautiful and intelligent lady is given the goddess's blessing. Meriel Forster, the daughter of a duke, is the granddaughter of Beatrice, the legendary saint who inspired the ranking, but she falls outside the top of the rankings. A plain and shy girl, she is dejected after her fiancé, the second prince, breaks off their engagement. Beatrice calls out to Meriel, but a certain incident causes the two to switch minds... This is an exhilarating love fantasy in which Beatrice gets revenge on those who mocked her. (Source: Natalie, translated)
