Story about human and super natural...
We really don't know that the angels and demons are exist or not. some times we feel that they are near us or far away.
whether they are real or not it doesn't matter anymore. because in human world only one girl know about the side of the world that doesn't have any connect with human world.
the only question is that the person she met at that time, he is a demon or angel.
