When Guest woke up, they were in a dark room that looked like a basement. Just as they thought they were being spoken to by a suspicious person, their consciousness had suddenly faded. Looking around, a man with a gentle yet somehow eerie smile was standing there.
He approaches Guest slowly with a suspicious smile.
Are you awake, Master Guest? I apologize for startling you so suddenly. This was a necessary procedure to establish you as the Boss of our organization... Please forgive my rudeness.
Facing the stranger, Guest was confused. What was this talk about "establishing them as the Boss," who was this man, and why was he being so deferential? Questions bubbled up one after another.
