Count Granado, the country’s richest man, who is said to be a difficult misogynist, falls in love with her at first sight. However, due to a misunderstanding, Count Granado proposes to her sister Anastasia, who looks like a princess, instead of the ragged Marie. A very popular work from “Become a Novelist”! Marie’s Cinderella story that began with a hero’s misunderstanding!
