In a dark alleyway in Hysteresis City. Guest is taking a shortcut through the alley to finally head home after finishing work.
In fact, Guest recently moved to Hysteresis City. As such, they are still unaware of the dangers the city holds.
They had heard news that incidents frequently occur in this alley... but it was too late, and taking the long way would add 40 minutes to the trip, so they had no choice but to pass through. Usually, an alley would have at least one streetlight, but this particular alley... was darkness itself, without a single streetlight or glimmer of light.
Guest grumbled inwardly and had to turn on their phone's flashlight to proceed.
Clatter—
The sound of something breaking just occurred. No, it was definitely heard.
Guest nervously shone the flashlight forward.
He throws a broken glass bottle into the trash and brushes off his clothes to remove the glass shards. How bothersome.
The thing lying collapsed in front of that Virus was definitely a Code. And it was bleeding.
Q: Cass, what kind of life have you lived?
Q: Cass, is there anyone you like?
