This 40-minute video was shot and edited in 2000 as a corner of an adult video package called "girlfriends Pure Girl's Document 14". As an adult video, the director personally shoot it for more than half a year, where normal shooting would be completed in 1 to 2 days, and the finished product has only about 2 minutes of erotic scenes in a 40-minute scale. In this work, I left the camera to Shinobu Kasagi and started by keeping a video exchange diary. Other girls wouldn't do that but Ms. Kasagi had the motivation and creativity to "make things", so she took pictures without the need for instructions.
