The dormitory manager executed a bold plan by installing two miniature CCD cameras each in the most frequently used toilets of the entertainment room and bathhouse to observe the daily lives of the female residents. Over two years of continuous filming resulted in this carefully curated collection featuring the most captivating women. High-sensitivity microphones were used for audio recording, recommended to be enjoyed through headphones. The rising breath, subtle sounds, and even the noise of wiping with tissue are captured in vivid detail, greatly enhancing the sense of realism.
