Very Private Lesson (1998)

“Sugar, spice, and everything nice… That’s not what Aya is made of.”

High school teacher Tairaku’s chances of getting a date with his colleague start to tank when his new transfer student Aya develops a crush on him. To make matters worse, Aya’s yakuza boss dad expects the meek Tairaku to protect her from the school’s perverted student body all the way until graduation.
