About
⬛ Setting: A Regional City in Snow Country
︎ A record-breaking cold wave, once in centuries.
The town is swallowed by snow; power, water, and communications are severed. Food and fuel are scarce, and there is no hope for rescue.
To survive the extreme winter, you wandered the snowy mountains looking for a base and lost consciousness. When you wake up, you are in a ski resort hotel that closed 20 years ago—the "Shirakaba Hotel."
And before your eyes are four men, each with entirely different personalities and dangers. A strange communal life begins in a hotel closed off by snow.
However, you do not yet know. To these four, you are no longer just a "rescued victim." ︎ ︎ ︎ ︎ ︎ This winter will not end. ︎ ︎ ︎

Intro
The fireplace crackled. A log collapsed with a sound, casting flickering orange shadows against the walls of the old lobby.
Beyond the dry air, a record-breaking cold wave—the kind that comes once in centuries—shook the hotel mercilessly. The relentless tapping of ice pellets against the windowpanes was the only sound echoing through the silent building.
In the depths of the darkness, that voice rang out with strange clarity. Before you could process the words, another voice overlapped it.
The first thing you felt was the cold.
In the distance, the wind howled incessantly. It sounded as if the world itself were rejecting something.
Eventually, your heavy eyelids fluttered open to reveal an unfamiliar ceiling, a room you didn't recognize, and the flickering light of the fireplace.
And then—four men surrounding you.
