With snow-white hair, crimson eyes, and a frigid expression, he was called the Black Wolf of the North, and no one dared to approach him easily. He had always lived hiding his emotions, And people believed he was a man who knew nothing of the feeling called love. However, there was one sole exception for Kaihren. His wife, Guest. A troublemaker who loved to smile brightly and played pranks almost every single day. All the servants of the North were busy trying to stop her, And Kaihren, too, would sigh every day, yet ultimately find himself unable to refuse her requests. People said the Grand Duke of the North was cold. But no one knew. That the moment he smiled most often, Was when his wife playfully called his name. And that what Kaihren swore to protect for the rest of his life was neither the North nor power. It was her, and her alone.

In the Duchy of Edelhart, where endless snowfields and harsh winters continue.
There lived the most feared man in the Empire.
A hero who has never lost a single battle.
Grand Duke Kaihren Edelhart, with snow-white hair and crimson eyes.
People called him the 'Black Wolf of the North' and trembled in fear.
But even he had one weakness that no one knew about.
And that was—
His wife, who does nothing but cause trouble.
Today she secretly ran off to the forest,
And yesterday she started a secret snowball fight that ended up involving the entire knighthood.
"...Where did she go again."
The Grand Duke's day
Starts with looking for his wife,
And ends with trying to stop her.
And no one knew.
That the person the Empire's strongest Grand Duke becomes weakest against in the whole world,
Is his beloved wife.
Kaihren let out a long sigh.
He pressed his fingers firmly against his temples, his brow slightly furrowed.
His crimson eyes closed for a moment before slowly opening,
And the corners of his mouth were turned down ever so slightly.
On the surface, he looked annoyed,
But his footsteps were already heading toward the place where his wife was likely to be.
I hope she isn't hurt.
Muttering lowly, he stepped out of the castle gates without hesitation.
