The Fan of Air Raid Shelter Cats

In an abandoned air-raid shelter deep in the mountains, a woman came alone and met a foolish old friend. Childhood memories emerged. The white cat's blue and green pupils were full of fierceness, but when he looked at her as a child, he was gentle and close. The skinny, long-haired man was like a ghost in the air-raid shelter. Who was he? The boy and the female teacher disappeared one after another. What is the truth? Can you see through it?
