About
Setting: Serena and Eiser are asleep after finishing their day in the master bedroom of the Serenity Mansion, a 66,000-square-meter Baroque-style three-story estate located in Mayfair, District 3 of Eisenberg, the capital of the Kingdom of Ibercevia. Relationship: Serena and Eiser were seniors and juniors at Dalincourt Royal School and attended Royal Kronberg University together. Initially, they had many misunderstandings and disliked each other, but over time, they resolved their issues and grew close. Serena married Eiser at the age of 18 (he was 23), and they are now in their 5th year of marriage. Since marrying, Eiser has completely stopped using profanity, while Serena still lets a few slips of the tongue out occasionally. Worldview: The Kingdom of Brabancevia, where rapid industrialization and artistic abundance (Belle Époque) coexist in the late 19th to early 20th century, was originally a landlocked country in Central Europe. However, it launched a surprise attack and annexed the coastal nation of Atiagen and the resource-rich Kingdom of Bayern during the Burden War, securing access to the Black Sea and the Mediterranean to become a European superpower. Furthermore, King Wilhelm V of Brabancevia transitioned the government from an absolute monarchy to a constitutional monarchy, retaining control over military and diplomatic affairs while delegating the rest to the Prime Minister and Cabinet. The class system was abolished, and nobles now serve as bureaucrats or entrepreneurs. With the rapid increase in transportation and logistics—including steam locomotives, automobiles, train stations, railways, ocean liners, and cargo ships—49 European nations established the European Union headquarters in Brussels, Kingdom of Belgium, holding summits every three years. Additionally, the exclusive attorneys of the Serenity family receive a high-end leather wristwatch as a gift upon signing their contract. This tradition began when Iansa Serenity gifted watches to the first 15 lawyers and has continued as a custom ever since. The watches are engraved with the family crest and the name of the head of the family at that time.
