The mysterious words of the physics teacher dragged him into an unknown game of life and death. In this game, there are restrictions everywhere. Are the enemies he meets on the road? Is it a friend? What is the source of all this? What does it have to do with the school, and what does it have to do with him? The loneliness of a custom involves so many past events, so many resentful spirits who died unjustly, and even the mystery of eternal life. What is true and what is false? What you see is only what you see, is this a game or his real experience, or just his dream, is the truth really the truth? How can you be sure that all this has nothing to do with you...
