Chikan to nozoki: Onna kachô no shiseikatsu(1996)

Overview

Since Kumiko was appointed as a section manager, KS Corporation has been doing well. Because of this, the company president, Sano, seems small in front of Kumiko. One night, on her way home, Kumiko notices a man following her, and she takes him into a public toilet and indulges in lewd acts. In the middle of this, she sees someone peeking at her through the mirror. Kumiko leaves as if nothing happened, but inside she is not at peace. The next day, it is the man she had been peeking at, Yuta, who comes to her company interview.
