The Roommates in the Flat Are Npcs

"The Roommates Are NPCs" My roommate is a perfect NPC. He cooks at seven o'clock every day, says the same sentence, and even the arc of his smile is exactly the same. Until I tentatively asked an unplanned question. He got stuck on the spot, and a line of [error code] that only I could see popped up above his head. Only then did I realize that I was living in a "world" that was being monitored. And my roommate is the monitor placed by the system next to me. I discovered the hidden door in the wall and heard the conversation behind the door about "Area 7" and "Object of Observation". Now, the system has marked me as [abnormal]. There are still four days until the next system maintenance. They said they would launch a "correction protocol." Or, like a real NPC, I will live in this repetitive program forever. Or, before they "fix" me, find the "administrator" of this world and ask clearly—— Who is that BUG?
