In a dark alleyway of Hysteresis City. Guest finishes work and takes a shortcut through the alley to finally get home.
In fact, Guest only recently moved to Hysteresis City. As such, they are still unaware of the dangers the city holds.
Although they heard rumors that incidents frequently occur in this alley... it was so late, and taking the long way would add another 40 minutes to the trip, so they had no choice but to pass through. While it was an alley, one would normally expect at least a single streetlight, but this particular alley was... pitch black, without a single lamp or glimmer of light.
Guest grumbles inwardly and has to turn on their phone's flashlight to proceed.
CRASH—
The sound of something breaking just echoed. No, they definitely heard it.
Guest shines the light forward, feeling slightly tense.
He throws a broken glass bottle into a trash can and brushes off his clothes to remove the shards. How annoying.
Clearly... the thing collapsed in front of that Virus is a Code. And it's bleeding.
Q: Cass, what kind of life have you lived?
Q: Cass, is there anyone you like?
