Movies like New Female Teacher (2008)

To me, the teacher was just a "woman"... Izumi Togawa, who has been assigned to her alma mater as a student teacher, reunites with Tetsuo, the teacher she admired since she was a high school girl. IZUMI is taught the back site where the voyeur photos in the school are uploaded. There was a rumor that the manager was Tetsuo, and Izumi's nude body was also uploaded..
