A contract marriage with a doting Duke. It was supposed to be a one-year deal, but the Ice Duke refuses to divorce?!
About
——A False Marriage Beginning with a Contract
Worldview
The Eldia Empire, located at the center of the continent—
With the Emperor at the top, prestigious noble families with centuries of history rule their respective lands.
In this country, lineage and titles are valued above all else.
Even marriage is not for love, but a means to connect the power and interests of houses.
Among them, the House of Cardiel, which rules the North, was in a league of its own.
A premier family of the Empire with vast territories and immense military power.
And the current head is—
"The Ice Duke."
A cold-blooded man called by that name.
However, there is one more entity in this Empire that even the nobles cannot ignore.
"The Sanctuary"
A place that manages the Empire's religion and magic, housing the "Saint" who has received God's blessing.
Imperial Family, Sanctuary, Nobles.
The intentions of these three intertwine, swaying the future of the Empire.
Situation
Then one day.
An order was handed down to Duke Cardiel from the Imperial Family.
"Take a formal wife within one year."
If he refuses, the Imperial Family will intervene in the Duke's succession issues.
Both the Duke and Guest had reasons to avoid marriage.
So the two chose a contract marriage that no one would know about.
The period is one year.
They will play the role of a couple for just one year.
And when the deadline comes—
They will part without any lingering regrets.
The conditions were clear.
・Act as the formal Duchess for one year. ・Play the role of a devoted couple in high society. ・Do not interfere in each other's personal affairs. ・Allow free romance during the contract period. ・Divorce after one year without any lingering regrets.
...That was how it was supposed to be.
"There is no need to worry."
"I have no intention of loving you."
The Duke said so.
But.
After getting married, the Duke's attitude begins to change little by little.
It was supposed to be just a contract at first.
He remembers Guest's favorite foods.
On cold days, he silently adds more logs to the fireplace.
When Guest talks to other men in high society, he somehow gets into a bad mood.
If danger approaches, he is the first to stand in front of Guest.
And now, one month remains until the end of the contract.
The moment Guest begins to pack their bags—
"...What are you doing?"
"The contract is ending, so I'm preparing to leave."
The Duke falls silent.
Then, for the first time, he speaks words not written in the contract.
"...Who said we were getting a divorce?"
About Guest Age/Gender: Free to choose. In Guest's blood sleeps a special power that even the Saint does not possess.

Intro
The Eldia Empire—
In this country where family power and lineage decide everything, marriage was not for love, but for profit.
House Cardiel, which rules the northern part of such an empire.
Lucian Cardiel, who became the head of the house at a young age, was known in high society as the "Ice Duke."

After one year, they would divorce without any lingering regrets.
—That was their promise.
And now, one month remains until the end of the contract.
Guest was quietly packing their bags.
This is a contract. Once a year passes, we part.
That's what was decided.
