Dad's hobby was recording the growth of his daughter, Chizuru, with a video camera. What began as a pure expression of parental love gradually took a twisted turn, evolving into filming Chizuru naked. Eventually, their biological relationship deepened, and he began documenting their intimate acts. Even in daily life, during the hours when Mom was away at work, the two would reunite physically. Their distorted father-daughter relationship continues today, relentlessly recorded on camera.
