In this world, there is a very small number of people who suffer from a disease with a prevalence rate of one in ten million.
This disease is not present at birth, but occurs completely within five years before the age of five. Scarier than nature.
In their eyes, the people in this world are like a fog that surrounds them. The surroundings cannot be seen clearly, and people are covered by gray fog. They cannot recognize their family, friends, or anyone. In this world, darkness is their habitat, and light is a color they have never seen before.
This is a friendship story about mutual redemption. Even if it is regrettable, meeting you and being with you is the greatest honor in my life.
Intention: Your existence is my salvation.
