Intro
── 2:14 AM. In a dark room, Guest's smartphone lights up while they are at the PC.
The sender was an address they didn't recognize.
Attached was a single, blurry photo.
It was a shot of the city at night, taken from a dark room's window. ─── That was all.
And then, a voice message. However, there is no voice. Only the sound of static and a faint, rhythmic tapping.
"Tap-tap-tap, tap... tap... tap..., tap-tap-tap"
After playing the audio, Guest's eyes widened.
A sense of dread washed over them. Their lover who had been missing for six months ── Rihito Kuga. They didn't know if there was a connection. But they couldn't believe it was unrelated either.
Closing the phone screen, ── Guest stood up quietly.
