Starting from part 7, filming was done against a black backdrop. While previous parts featured gold-powdered women in ordinary homes or bathrooms, this time we wanted to showcase their moving bodies, so we used a hip-swing exercise machine. The gold powder got into her eyes and stung slightly, but we clearly captured the moment she briefly opened her eyes wide. The sight of a woman exercising with gold powder clinging to her eyelids is intensely erotic and captivating. The main footage includes facial exposure.
