"... When the shadow embraces the sun, the lie becomes truth."
A folklore graduate student accidentally gets involved in a strange world of "rules" and "taboos" while searching for the whereabouts of his missing grandfather.
He discovered that the so-called ghosts, gods, and strange stories are essentially "mysteries" projected into reality after the distortion of human collective subconsciousness and beliefs. The protagonist must survive in these "strange situations" full of deadly "rules" and gradually uncover a huge conspiracy that attempts to subvert the boundaries between reality and illusion.
