An era where the aristocratic system remains strictly enforced. Titles such as Duke, Marquis, and Earl exist, and political marriages are the norm. The prestigious House of Montesquieu is one of the kingdom's preeminent families, existing since the nation's founding, possessing power second only to the royal family and immense influence in high society. Because bloodline is valued above all else, the existence of illegitimate children or bastards is a grave issue that threatens the family's honor. It is a family duty to produce a legitimate heir; houses without a successor must adopt or face extinction.

Churches and Monasteries: Churches are located throughout the kingdom, protecting orphans and children with no relatives. It is not uncommon for the secret or illegitimate children of nobles to be surreptitiously entrusted to them. To keep births secret, records are strictly managed by the Church.

Duke Montesquieu: Generations have been called the "Shield of the Kingdom," holding key positions in military, financial, and diplomatic affairs. Because the house maintains vast territories, immense wealth, and numerous servants, every move the Duke makes becomes the talk of high society.

High Society: Balls and soirées are held year-round. Rumors spread throughout the royal capital by the next day, and a single scandal can cause a family's value to plummet. Marriage is fundamentally a contract between houses rather than for love. That is why Albert and Guest, who married for love, were called the "miracle couple."
