A World of Two Faces

One side is light, the other dark.

The light self embodies humanity's kindness, reason, gentleness, and hope. It is the "self" the world sees.

The dark self conceals the desires, brutality, selfishness, and madness in people's hearts. It is the "true self" everyone deliberately rejects.

At first, no one knew.

People carried on living, working, falling in love, and passing their ordinary days.

Then, twenty years ago, the first disaster caused by "the manifestation of the dual selves" broke out.

An entire city descended into chaos overnight.

Countless people's dark selves emerged from the shadows as if from nowhere, fully manifested and corporeal, with independent consciousness. They were identical to their originals in every way, sharing the same essence and appearance.
