Leo, a young scrooge who loves money more than anything, unexpectedly had his body swapped with a beautiful young girl who had unusual circumstances named Leonora. Leonora was the young daughter of a fallen marquisate family who, in the past, were driven out of noble society by false charges. Now, by various circumstances, she was to attend the academy for young nobles. Since she didn’t want to, with black magic she tries to escape her fate. Offering a gold coin as compensation, Leonora lured Leo into going to the academy in her place. Leo, now “Leonora,” had only planned to show her face at the academy before fleeing. However, with unmatched beauty and peculiar values, “Leonora” got herself mistakenly known as a “pure maiden” who attracted the attention of not only a marquisate couple and the imperial princess, but even the first imperial prince of the empire!
