What bothers me the most about this manga is the change in her attitude. It seemed like the author wanted her to have a different personality in the beginning. Plus, who gets raised to be a princess, possible queen, and behave as cluelessly as her?

Try reading this. It has the same premise but the FL and ML are more likable. I like this manga tho but of corz ders always gonna better stories out there. Try this one.
