In desperation due to financial difficulties, I turned to my good friend Matsumoto for help. He proposed attending a startup gathering party where he thought there might be potential investors. Although it seemed suspicious, I decided to trust him and follow his lead. Upon entering the venue, we were met with an eerie atmosphere; all attendees wore masks while watching others have sex on stage. As I watched, a woman resembling my wife began performing herself. It was clear that this event catered to those seeking illicit thrills through voyeurism or even participation themselves.
