Daily Exploration

Slight fear, light novel. What would happen if we could constantly switch between the inner and outer worlds? From that moment on, the "snow" stopped, the "light" went out, and I held the ax left by my grandfather tightly in my hand, waiting for death to come.

It's like, my future self is now dead in the past.
