In this world, there are two spaces, one is called the human world and the other is called the ghost world. In order to maintain the balance between the two worlds, spirit beings appear. Their mission is to help the ghost officials, bring ghosts back to the ghost world, and investigate supernatural cases in the human world. It takes hundreds of years to accept that one is a spiritual person, but for them, this is not a long time, even if the process is cruel. A hundred years later, is the person left by your side still the same person as before?
Purpose: I hope that in the long river of time, we can all find the meaning of existence
