Love - 0 = Infinity (ＬＯＶＥ－ＺＥＲＯ＝ＮＯ ＬＩＭＩＴ) aka Dirty Wife: Getting Wet or Filthy Wife: Wet (いやらしい人妻 濡れる Iyarashii hitozuma: Nureru) is a Pink film directed by Hisayasu Satō and starring Kiyomi Itō. Shinji Imaoka served as Satō's assistant director on the film. It was named Sixth Best Film of the year at the Pink Taishō ceremony. According to Allmovie, it was the first Japanese film to deal with the subject of AIDS, though Jasper Sharp points out that Satō had previously used the subject in Survey Map of a Paradise Lost (1988).
