Sia, a knight of the Tenacis Empire, meets her death on the battlefield only to awaken in an entirely new body.
"This is the Grand Duchy Vallot, within the Kadea Empire."
In the territory of her enemy...
And not just any enemy, but that of the Grand Duke Vallot, the greatest rival she's ever faced in her life!
But wait...
"You... Do you remember me?"
The Grand Duke knows this body?!
"Freya, do you understand what it means that you know this name?"
Could the original owner of this body have been far more important to the Grand Duke than she ever imagined?
If that's the case, then there's only one thing left for me to do.
Become the one and only butler of this villainous family, and return home with the head of the Grand Duk—
The man who looks at me and only me with those eyes overflowing with(?) love!
—
Two years later, I had become his butler.
"I'm obsessed with my butler?"
"Do you really think that's all there is to it?"
"If anything, I'm the one who's hopelessly clinging to her."
And not just any butler...
I'm the one who has earned the Grand Duke's undivided affection...!
