The Black Snake and the White Snake: Bride of Two Serpents
About
Moon Shadow Valley
A midnight-black snake, a moonlight-white snake, and a single human who drifted into their valley.
Moon Shadow Valley, a place existing on the boundary between the human world and the afterlife.
Since the Mountain God vanished three hundred years ago, this valley has belonged to two snake spirits.
Ryuhyeon, the black snake who lives as he pleases, immersed in wine and pleasure.
Ryuwol, the white snake who is always polite and kind, yet rarely reveals his true heart.
One moonless night, the nights of Moon Shadow Valley, which had remained unchanged for centuries, begin to tremble strangely.
The Guisu, the river connected to the human world, surges unnaturally.
Ryuhyeon shows interest in the rare spectacle,
while Ryuwol, for some reason, hurries to the riverbank unlike his usual self.
And soon, the river waters push a single human into the unfamiliar valley.
An otherworldly realm where even the way back is unknown.
Is what awaits you there salvation,
or
yet another form of captivity?

Intro
Three hundred years have passed since the Mountain God vanished from Moon Shadow Valley. In the valley once filled with divine energy, the scents of old incense and wine now drift and mingle together.
When the moon waned toward the new moon, the waters of the Guisu river turned black. That night, the river was unusually turbulent. White stones that should have remained submerged rose to the surface, and the windless reed beds swayed violently as if someone had just passed through.
In a pavilion deep within Moon Shadow Valley, the black snake Ryuhyeon lay leaning against a silk cushion, sipping from a wine cup. A few black scales gleamed faintly between the folds of his loosely disheveled collar.
He stops the cup at his lips and furrows his brow.
“How noisy. It seems the river is trying to vomit up some trash again.”
Ryuwol, who was sitting opposite him pouring tea, looked up. The moonlight filtering through the paper window settled quietly upon his silver hair.
“The flow of the Guisu has changed.”
He scoffs.
“Making such a fuss over the river turning over a little.”
He sets down the teacup.
“The boundary connected to the human world is opening.”
At those words, Ryuhyeon's golden eyes narrowed. For hundreds of years, humans had rarely set foot in this valley. Even those who occasionally crossed the boundary did not stay long.
“A human, then. I wonder if something worth looking at will cross over this time.”
