Deep Space Corridor

When memories start to flicker, how do you confirm that "you" still exist? On a strange planet, the city is blocked by an energy dome, and a silent black cube hangs in high orbit. People live seemingly perfect, stable lives—no chaos, no surprises, and no superfluous emotions. Until, someone "misses". There are no traces, no records, as if it never existed. And one day, you find that in another invisible city, another "you" is living another life. When the boundaries of the two worlds begin to overlap, and when your name appears on the "recycling list," how do you prove: I am here? Cross the gap between memory and reality and pursue the truth of existence. In this corridor at the end of deep space, every answer may destroy your entire understanding of the world.
