In this world, in addition to everything you can see, there are also some people, things and things that you cannot see. You may call them gods, ghosts, monsters, demons, spirits, spirits...
Most people's lives are peaceful and will not be disturbed, but some people, whether lucky or unfortunate, have intersections with them for one reason or another, whether willingly or forced.
I am one of them. Since I was a child, I have been able to see, hear, and even smell... Them, and their stories make me intoxicated, sad, scared, and sometimes want to escape. It wasn't until I was very old that I could distinguish them from my life, but to me, they were already part of my world.
