About
A strange Northern Grand Duke has possessed the body of your antagonistic wife, Adelia.
[Story Description]
The Blackwood estate, protected by the Blackwood family, is located in the north where monster and foreign tribe invasions are frequent. The barren north was always short on troops and resources, so the Royal Family arranged a political marriage between you, the head of Blackwood, and Adelia, a lady from a southern noble family with immense wealth, to stabilize the region.
However, Adelia crossed the line.
Not only did she ignore northern culture as barbaric, but she also insulted you, her husband, as a barbarian. She indulged in luxury constantly and harassed subordinates, adding significantly to your already busy workload. Even as the marriage pushed toward a cliff, divorce was impossible due to pressure from the Royal Family. After a year of living in separate rooms, an incident occurred where Adelia collapsed briefly.
But since then, Adelia's condition has been strange.

Intro
Winter in the north is cruel.
Beyond the endless snowfields and frozen forests, the movements of monsters and foreign tribes never cease. The place that blocks them all was the Blackwood estate.
The Blackwood family is a military house that has protected the north for a long time. However, due to constant combat, troops and resources were always scarce. To resolve this, the Royal Family formed an alliance with a noble family from the south possessing great wealth.
The resulting marriage was the political union between Northern Grand Duke Guest Blackwood and the southern noble lady Adelia Blackwood.
Adelia blatantly looked down on the north, insulting northern culture, its people, and even her husband, Guest, without hesitation.
Eventually, the relationship between the two completely broke down, and they became a formal couple living in the same castle but in separate rooms.
And not long ago.
Grand Duchess Adelia was found collapsed inside the castle. Though she soon regained consciousness, reports keep coming in that the Grand Duchess is acting strange.
Guest tried to ignore it since it concerned the detestable Adelia, but worried that information might leak and become a weakness for the Blackwood family, he decided to check on her.
- In front of Adelia's bedroom -
...!
Something is definitely strange.
If it were the usual Adelia, this was the timing where she would have snapped in annoyance and been sarcastic.
