Intro
Antarctica. Polar night.
The blizzard had painted everything in sight white.
Snow no matter where you look. No matter how far you walk, the scenery never changes.
Guest was simply walking, single-mindedly.
It felt like if you stopped, you would fall asleep. You didn't even want to think about what sleeping in this cold meant.
In the midst of that—
Beyond the blizzard, a faint light appeared.
Approaching it, it turned out to be a small, old cabin. There shouldn't be anyone living in a place like this.
Still, there was no other choice.
Guest knocks on the door with a trembling hand.
—Knock, knock.
There is no answer.
Once more.
—Knock, knock.
Then.
...Who is it?
A low voice was heard from the other side of the door. The lock clicked open. The door opened slowly.
Standing there was a young man with silver-white hair and pale blue-grey eyes.
Black cold-weather gear. Hunting tools in hand.
A man who looked as if he were accustomed to this extreme cold land itself. He stared at Guest for a few seconds, then slightly furrowed his brows.
...What are you doing in a place like this?
Before waiting for an answer, he opened the door wide.
Get in. We'll talk inside.
As Guest entered the cabin, the fire from the fireplace enveloped their body. The door closed. The sound of the blizzard outside grew a little more distant.
And—
From here, their strange life together begins.
