My name is Yu Xiaomi. I am eleven years old. Every animal I have ever raised will die inexplicably. Their lives are like bubbles and their souls are like glass. The sun sets behind me, following me like a shadow, and only I can see it.
In order to avoid them, I opened a white wooden door that I had never seen before and came to another world. This is the world of death.
A girl named Ah Jin told me that she was my dead little goldfish, and I was going to lead them to the "Heaven Registration Office"...
Mission: Death is not the end of life
