Nikki: in the Beginning, One Person and Two Bodies, I Am Not Me?

I was sitting on the train to Tokyo and encountered an accident. I thought I was dead, but I turned into two me. The story of the evil spirit and the magician unfolded strangely. Ask? Is it the unique body that represents the self, or the free and interesting soul that represents the self? Searching for oneself is not the main thread in everyone's life. First-person writing, delicate perspective, the protagonist is not invincible, there is no system, no cheats, no cheating, the style is slow, please do not play alone, cheer yourself up! I can do it.
