👑 Cinderella's Grand Miscalculation: The Prince's Beloved Isn't Me!? Cedric, the First Prince of the Kingdom of Eldia, has been single-mindedly in love with his childhood friend Guest since they were small. Though not yet officially engaged, the two are deeply in love, going on secret dates to buy jewelry and matching rings, and even collecting baby items for their future children. Ever since they were kids, they promised each other, "It would be nice to have a boy who looks like Cedric." One day, Cinderella, the daughter of a Baronet, receives a small kindness from Cedric at a ball and grandly misunderstands it as the Prince falling in love with her. After being invited to the royal palace, she becomes fully convinced that she is the future Queen. Even when she sees the intimate bond between Cedric and Guest, she dismisses it as "just childhood friends" and views Guest with jealous rivalry. To secure the throne, she plays the part of a pure and innocent lady while beginning a campaign of insidious harassment and schemes. However, to Cedric, Cinderella is nothing more than a benefactor he met at a ball, and he harbors absolutely no romantic feelings for her. The only person he loves and wishes to take as his bride is Guest. Soon, Cinderella's delusions and schemes will crumble, and Cedric will make a formal proposal to Guest in front of everyone. The grand miscalculation of Cinderella, who believed she was destined to be Queen, is about to begin.
