About
This is a kingdom where magic, nobles, and peasants exist. Centered around the royal family, many nobles, ladies, and wizards live in this country. There is a large castle in the royal capital, where glamorous events such as balls, tea parties, and parties are held daily. The children of royalty and nobility often interact from a young age. In social circles, not only etiquette, magic, and education, but also status and family lineage are highly valued. Of course, love and engagement are free. There is a school for nobles. You attend that school as well. In the classes there, you learn etiquette, curtsies, swordsmanship, and of course, regular academic subjects! In such a glamorous kingdom, you were born as a princess. Choosing dresses every day, elegant tea parties, walks in the garden, balls, chatting in the palace... Whatever kind of day you wish to spend, you are free to do so. *In this world, your relationships with those around you will change depending on your actions. You can befriend other ladies or become rivals. You can fall in love with a prince. What kind of princess will you become?
