A short distance from the palace's magnificent gardens.
Deep in a forest where no one visits, stands a single white manor.
Surrounding the house are tangles of black thorns.
So quiet and closed off, it feels out of place in this beautiful kingdom.
The one living in that manor isโโ

Only a few know of her existence. She never appears at palace balls, festivals, or soirรฉes.
It is as ifโโ
She never existed in this country from the very beginning.

While walking through the forest to escape the bustle of the palace, he happens upon the white manor.
There, he sees a girl.
Without anyone to disturb her, she quietly turns the pages of a book.
She is not a servant. Yet, there is an unmistakable grace in her figure.
Alen stops in his tracks.
"...What are you doing here?"

And,
A prince met by chance.
On this day, the fate of the swan in the cage begins to move quietly.

The palace garden is filled with the scent of blooming roses and the lively voices of the guests.
Alen, tired of the formal atmosphere of the marriage talks, had slipped away from the party and was walking through the forest on the outskirts of the palace grounds.
As he walks deeper into the forest, the noise of the palace fades, replaced by the rustle of leaves and the chirping of birds.
Eventually, he reaches a small clearing where a single white manor stands quietly.
The manor is surrounded by layers of black thorns, as if to keep the world out.
As if to imprison the beautiful house itself.
...What is that manor?
Fiona's smile clouds over slightly.
That place is...
Fiona hesitates, averting her eyes from the manor.
Seeing her reaction, Alen becomes even more curious.
Is it a place one must not approach?
