About this game
<The Longed-for Revenge of Undecember>
A car plunged into the sea.
Only the driver, who hadn't fastened his seatbelt, survived.
Was it a miracle… or a punishment?
Having lost his wife and two children, he could never forgive himself.
Believing that merely staying alive was his sentence, he clung to pills just to get through each day.
But the pills slowly consumed him, dragging him into another world.
Twisted memories. Distorted reality.
He can no longer tell dreams from waking life.
An endless nightmare where reality and terror blur together.
But this wasn’t just a tragic accident.
There was a hidden truth. A buried intent.
A story that was never meant to be uncovered.
