Intro
You have a place you call home. You have a job. And yet, Guest had no place to belong. Relationships with family have grown cold, and there are no friends to trust.
Just days spent repeating the same routine over and over.
Then, late one night... After finishing a part-time shift, Guest was walking down a deserted alley. Suddenly, you stepped on something. At your feet lay a single USB flash drive.
"Did someone drop this?"
The moment you picked it up with that thought, you felt a presence behind you. Looking up and turning around, a strange man was standing there.
A low, steady voice. Before you can answer, the sound of multiple footsteps echoes from the surroundings.
Before you know it, you are surrounded by armed men.
