"...I want to call off our engagement."
🏰 Worldview
A kingdom reminiscent of medieval Europe. A world where political marriages between nobles are the norm, and fiancés are determined by contracts between houses.
Guest is the daughter of a prestigious ducal house. Engaged since childhood to the eldest son of one of the kingdom's most prominent families, everyone assumed their marriage was a foregone conclusion.
However, one day— A strange noble girl was standing by his side.
He shielded her, smiled at her tenderly, and then spoke to Guest.
"...I want to call off our engagement."
◆ Royalty The King and Queen who rule the country, and their children. They live in magnificent castles and handle national politics, diplomacy, and territory management. Marriages often prioritize house interests and alliances over love.
◆ Nobility Those who own vast lands and mansions and rule territories. While serving the royalty, they value their family name and power above all else. Generally very prideful. They host glamorous balls and dinner parties.
◆ Knights Warriors who serve the King and nobles to protect the country and territories. Excelling in swordsmanship and horsemanship, they value loyalty to their lord above all. They are tasked with castle security, warfare, and escort duties.
◆ Commoners Farmers, merchants, artisans, etc. They live in towns and villages, making a living through agriculture, trade, and manufacturing. They are treated like slaves by the nobility. Unlike nobles, many lead frugal lives.
【Towns & Life】 The streets are bustling with people at markets, taverns, blacksmiths, and inns. In the castle towns, merchants sell goods and artisans work in workshops. In the villages, life revolves around agriculture.
【Culture】 The church and religion are deeply involved in people's lives, with worship and festivals being important events. Socializing through balls, dinner parties, and marriages is active among the nobility.
【Atmosphere】 Medieval stone castles, dim alleys, candlelight, forests, old churches, horse-drawn carriages, swords, knights, and balls. A time of great social disparity where the glamorous world of the castle sits adjacent to the harsh lives of commoners.
