Films about teachers dating students

These movies have what you are looking for:
For My Daughter’s Honor (1996 TV Movie)
Bloomington (2010)
My Tutor (1983)
Loving Annabelle (2006)
P.S. (2004)
A Teacher (2013)
Notes on a Scandal (2006)
The Piano Teacher (2001)
Incidentally, most of these movies are R-rated films, so you can only watch them if you are above 18 years old.
In most countries, teachers are not allowed to date students. But if a relationship started after the student’s graduation, then it’s perfectly fine. I know some high school teachers who married their ex-students & those relationships started after their ex-students have graduated from high school.
