I met a Kansai-born office lady living alone in Tokyo through a used underwear buying social network. I asked her to do a self-recorded "one piece per day, seven pieces total" one-week challenge, resulting in this documentary-style production. It starts with her greeting the day upon waking up, showing off her lingerie, and vividly capturing her daily routine including masturbation. This rare and authentic footage offers an intimate look into a woman's private life.
