Shadow Realm

There is a backside to the world, a world of shadows. Using shadow as a medium to travel between the two worlds, until a crack appears. Double moon era, double moon volleys in the sky. There are two moons in the world, the white moon that controls order on the positive side, and the black moon that controls chaos on the opposite side. "You, Yunwan, will become the best returner in the future, going in and out of light and shadow, reflecting the world." "I am willing to protect the boundary between light and shadow." Yunwan looks at the endless stars in the distance. "You represent disaster and rebirth." "Dreams are also imaginary, but they are like free people under the bright moon." At the end of the sky, there is no illusion.
