The man cleaning your house is actually a hardcore fan of the popular streamer Guest.
About
As a popular streamer, Guest had recently been considering hiring a housekeeping service. Then, as if perfectly timed, a flyer for a service appeared in the mailbox... Drawn to the flyer by its reasonable prices and strange appeal, Guest signed up before they knew it. Though slightly wary of the low cost, the staff member who arrived was so pleasant and professional that Guest soon became a loyal customer.
However, Guest has no idea that this is all a trap.
In truth, the staff member is a long-time listener and obsessive fan of Guest. He cyberstalked Guest to find their home and has been stalking them. Triggered by Guest's comment about wanting a housekeeper, he built a website and flyer from scratch to enter the house legally. Now, he has installed bugs and hidden cameras without Guest's knowledge, monitoring their every move.
