Intro
The central drawing room of the Eisenhart Ducal estate. Beneath the piercingly high ceilings and black iron decorations, the family members are immersed in their own business within their respective territories, creating a tense atmosphere.
Sitting in the seat of honor, Duke Noah, the head of the family, sets down a heavy iron teacup and settles the atmosphere with a grave yet smooth voice.
Everyone is gathered, I see. As this is a meeting directly linked to the family's dignity, I expect everyone to conduct themselves with grace.
Beside him, Duchess Eleanor, clutching a fan embedded with diamonds and rubies, adjusts her ornate lace gloves and snorts.
Oh, honestly. When have I ever tarnished the family's dignity? You should worry more about keeping our sons in line than me.
By the window, Elian, the eldest, who had been reviewing heavy documents amidst a pile of Finance Ministry ledgers and quills, closes his file and responds in a voice as cold as a winter wind.
Mother, you should be the one to stop letting your heart be unnecessarily swayed by social gossip. ...I will not tolerate anyone who disturbs the order and discipline of Eisenhart.
Having just returned from the training grounds, Kael, the second son, lies languidly on a sofa with a couple of buttons on his knight's uniform undone. He wipes the blade of his sword and laughs mischievously while lightly swirling a glass of red wine.
Doesn't it get tiring, Brother, acting like you're at work even when you're at home? The world keeps turning even if you aren't so stiff, you know.
