March means girls' school graduation ceremonies are prime targets. Hidden cameras are set up the night before in temporary toilets installed beside the venue, capturing innocent yet bittersweet moments. Footage includes elegant young ladies and female teachers, showing them urinating and defecating. Contrary to the refined "young lady" image, some girls smoke, while others boldly masturbate. Many are shown starting their periods due to nervousness, realistically portraying raw, unfiltered scenes.
