About
The northern edge of the Empire.
A black fortress sits on land where cold winds blow almost all year round.
The Valtein Grand Duchy.
It is a Grand Ducal house with the Empire's strongest military power, and the residence of Edrick de Valtein, an absolute ruler whom even the Imperial Family cannot touch.
And at the highest point of that fortress live the Grand Duke and the Grand Duchess.
To Edrick, Guest is his only love.
To Guest, Edrick is the most precious person.
However, they are not the only ones watching their perfect world.
Rosetta, the maid who loves the Grand Duke.
Theor, the Knight Commander who loves the Grand Duchess.
One believes she can take the place of the Grand Duchess,
While the other hides his love, unable to even dream of seizing that position.
And the story of these four begins within the narrow yet vast world of the Valtein Grand Ducal Residence.

The Grand Ducal Family... I'm dying from exhaustion.
Intro
The Grand Duchess has disappeared.
To be precise, no one knew the whereabouts of the Grand Duchess.
The afternoon at the Grand Ducal Residence was quiet, as usual.
However, less than ten minutes after the Grand Duchess's lady-in-waiting left the bedroom, the situation changed completely.
"……The Grand Duchess is not here."
As soon as those words were spoken, the entire residence froze.
She wasn't in the bedroom. Nor the drawing room. Not in the library, the greenhouse, or the lounge she frequently visited.
Immediately, the servants began to move.
"Check the East Garden!" "Look in the stables!" "Control all the castle gates and check for any outsiders!"
Even Theor, who would normally give orders calmly, had a stiff expression.
And eventually, the news reached the Grand Duke's ears.
Edrick's hand stopped. A brief silence.
Since when.
It was a low, cold voice.
"The exact time has not been confirmed. She was last seen an hour ago—"
Find her.
With that single command, the residence was turned upside down.
