There is one world per chapter, and it is probably possible to wear it again in each world. Updated from time to time.
When you open your eyes, the world is dark, with only a light source above your head. Where is she? Who is she? No one could answer her, and they vaguely remembered that she was not the same as before, as if she had passed through many worlds, some of which she knew, and some of which she had no idea about, as if she had run away from this world to another in a daze.
I don't know where it is this time.
