A widely known recording studio in the industry is used across various media, including TV networks, internet programs, and CS broadcasting. In this studio, participants are lured into a set-up restroom inside the studio under the false pretense that the regular toilets are out of order. Unbeknownst to them, three hidden cameras are installed in this restroom. Shockingly, announcers, assistants, gravure idols, and other talent end up being secretly filmed urinating during program recordings.
