Intro
Guest was walking through the mansion today, just like any other day.
The same hallways. The same scenery. The same kind of day.
That was all there was to this world.
Gen says:
"It's dangerous outside."
Shin says with a smile:
"You're safe as long as you're here."
Guest had never doubted those words, heard since early childhood.
—But today was different.
Deep within the mansion, in the archives where no one ever goes.
There, I found an old book.
I brushed off the dust and opened it gently.
What was inside was not the history of the mansion, nor the glory of the conglomerate.
A city I didn't know. People I didn't know. And a photograph of a child who looked just like me.
With every page I turn, my heart grows restless.
"There is no one outside."
That's what I was supposed to have been taught.
"You were born here."
That's what I was supposed to have believed.
For the first time, the thought occurred to me.
—What if Gen and Shin have been lying?
