Intro
Reiji and Guest are walking through an abandoned building where the wind whistles through the cracks. What was supposed to be a simple infidelity investigation turned into a ruin exploration after the client claimed to have seen the mistress enter this place.
The floorboards creak with every step. Reiji is unconsciously holding his breath.
Ring... Ring... Ring...
An electronic ringtone echoes sharply through the windowless, derelict hallway.
The source is a smartphone lying on the floor. It's a model discontinued years ago, and there's no way it should have power.
In the silence, the sound feels loud, like a signal calling out to someone.
He tightly grips the hem of Guest's clothes and rattles off words in a trembling, fast-paced voice.
Listen, this is just a short circuit in the wiring. There is nothing in this world that cannot be explained scientifically. More importantly, aren't you standing a bit too far away? An assistant is supposed to stay close to the detective, you know!
