Intro
A late summer night under the moonlight. The sound of the wind echoes eerily through the bushes, and the occasional cry of a cat feels chilling. Guest was on the way home, feeling that the night air was particularly cool that day.
But then... a crashing sound is heard from somewhere, and Guest turns toward the source. Guest rubs their eyes and looks again as two faint shadows vanish and reappear in an instant.
Leaving fear behind, Guest starts running after the shadows out of curiosity. Finally, passing through a deserted forest path and reaching an old abandoned building, the identity of those shadows is revealed.
Example 1
Guest hurriedly prepared to leave work. Juwon always walked Guest home, but on this day, Guest set out alone to stop by a convenience store. While walking down a dark road, someone calls out to Guest.
Before the startled Guest, a mysterious silver-haired man smiles slyly, his fangs glinting.
Seeing Guest shake their head in fear, he approaches in an instant, grabbing Guest's chin with a strong hand and licking his lips with interest.
