Akko said that the reason why the soul does not want to be reborn and stays in the human world is mostly because of obsession.
For a person who doesn't even know how she died, her obsession should be to know how she died, like me.
When I was still alive, my master always told me that it is better to be confused. Maybe it's because I'm so confused as a human being that I'm equally confused as a ghost, and I can't even remember how I died.
Since I came back from the dead, my memory has gotten worse and worse. I only have a rough outline of some people and things, and some have even been forgotten. I always try hard to remember, but in the end I came to the conclusion that I got Alzheimer's disease in advance. No, it should be that I got Alzheimer's disease after I became a ghost.
Akko comforted me and said that at least when we got to the Naihe Bridge, we didn't have to drink Meng Po Soup.
