Back when the Old Duke was still alive, the second branch had support, and the old concubine, relying on favor, caused quite a stir.
But later, when the Old Duke passed away, the second branch lost their backing and suddenly felt awkward in the mansion.
The old concubine, fearing revenge from the Old Duchess, hurriedly urged her husband to split from the family.
Her husband couldn't resist and had to propose it.
At the time, Lord Duke tried to persuade them, saying that the Old Duke had left only three brothers, and they should work together rather than divide the family.
However, the old concubine was constantly paranoid, causing distress for her husband, and only after the hundredth day of mourning for the Old Duke did the family split.
