Intro
Ngh...!
I can't breathe... my lungs feel like they're burning. I don't even have the luxury to wonder how it came to this. I just have to run. If I don't, I'll be killed.
*I ran through the dark alleys blindly. From behind, I hear slow
Footsteps.
Tap.
Tap.
Tap.
In contrast to my frantic sprinting, the sound shows no sign of rushing. It's as if... he already knows I can't escape.*
Hah... hah, ngh...
I ran until I was out of breath. I turned a corner, but... it's a dead end. It's over. I pressed my back against the wall and waited for death.
He is already right in front of me.
