Storyline

I overslept the last train and ended up at a strange place called "Saihate Station". "Haru Akinashi" is a servile office worker who lacks self-confidence and is no good at anything he does. After sleeping in the last train, he finds himself trapped in a strange place called ``Saihate Station'' where horrific and mysterious phenomena occur. "Shion Tatsunami", a bright and talented colleague and former friend who is in contrast to the protagonist, also happens to be there, and they promise to cooperate and return together. The two had been estranged for a while, which made things awkward at first, but each time they overcome difficulties, they remember the distance they once felt and deepen their bond even more. The truth of the world approaches there. What are the consequences of perverted emotions? Where did the two end up?
