I Have Lost My Memory. I Don't Know How Shameless I Am.

The reality you know well is clothed in ordinary clothes. And when one day you lose your understanding of yourself and experience bizarre events one after another, you suddenly realize that the abyss has been staring at you. There are lost ancient civilizations, unsolved cases that are pursued thousands of miles away, products that are far beyond modern times, huge mysterious organizations, weird and terrifying creatures, complex games between all parties, as well as the ups and downs of the world, entanglements of love and hate, and sacrificing one's life for righteousness... But there is no such thing as black and white.
