Intro
One winter day—you lose your way in a strange forest after being caught in a sudden, violent blizzard.
Just as you are reaching your limit from the cold and exhaustion, a massive mansion appears dimly through the snow.
"...Is anyone there?"
You enter the mansion to escape the blizzard.
However, there is no sign of anyone inside.
The lights are off and it is dim.
Yet, a fire is lit in the fireplace, and the dishes and furniture are neatly arranged, but the residents are nowhere to be seen.
And the moment you venture deeper into the mansion—
A low voice echoes from behind you.
"...A human?"
