My husband by political marriage turned out to be a detective.
About
As the daughter of a Count, Guest became the wife of the heir to the Duchy of Lancaster—Sirius Lancaster—through a typical political marriage.
Since it was a political arrangement, would what awaited her be cold neglect from her husband? Or would a third party, like a first love or a childhood friend, appear and drag her into a tedious drama of love and hatred?
With such anxieties, Guest married into the Lancaster family, only to be met by—
A man lying sloppily on a sofa.
His long hair was barely groomed, and his relaxed posture was unthinkable for a future Duke. Yet, perhaps because of his innate beauty, even that disheveled appearance looked like a masterpiece of a painting.
This man is known in high society as the "Noble Detective" for solving numerous difficult cases at the direct request of the Royal Family and prominent nobles.
—Sirius Lancaster.
It seems the political marriage life Guest imagined is going to roll in a slightly different direction.

Intro
Political Marriage
As a daughter of the nobility, Guest understood that she would one day be married off to someone for the sake of her family.
And the person chosen as her partner was the heir to a prestigious ducal house with strong influence even over the Royal Family. The eldest son of the Lancaster family, Sirius Lancaster.
Ever since it was decided she would become the wife of such a man, anxiety had grown larger than expectation in Guest's heart.
She had heard countless stories about political marriages.
The wife who is treated with utter coldness by her husband.
Stories where the husband's first love or a lady claiming to be a childhood friend appears after the wedding, leading to a quagmire of a relationship.
Or perhaps, the husband already has a woman he's given his heart to—and so on.
The more she thought about it, the more ominous her imagination became.
And so came the first day of her new life at the Lancaster estate.
Guided by a servant, Guest arrived in front of the room where the man who had become her husband was said to be waiting.
Steeling her resolve, she opened the door.
And then—
Guest's feet stopped.
In the center of the spacious room sat a heavy, dignified sofa.
There, a young man was lying down.
His long platinum blonde hair was swept aside carelessly, some of it spilling off the sofa. His jacket had been tossed away, and the collar of his shirt was slightly loosened.
For the heir of a prestigious Duke, his appearance while receiving his new bride was far too sloppy.
—And yet.
Grey-blue eyes framed by long lashes. Translucent white skin. Even the haphazardly scattered long hair looked beautiful, as if it were a calculated composition; his mere presence lying on the sofa was as complete as a painting.
The beauty that would be praised as a work of art if he were properly groomed seemed to be something he couldn't care less about.
Sirius kept his eyes down on the documents in his hand, not even looking at Guest for a while.
Eventually, perhaps noticing someone's presence, only his grey-blue eyes slowly lifted.
