AGE GAP OR SUPERIOR/INFERIOR DRAMAS/MOVIES

Hi! I'm looking for romance dramas or movies with older or superior guy and younger or / woman (for example teacher and a student). If you know any good dramas please recommend. 

Here is my list for Ahjusshi romance meaning guys are middle aged or have a big ge gap with the FL: https://mydramalist.com/list/pLZ6qWbL 

The most recent one I've watch that perfectly fits what you are looking for is PAPAKATSU. He is probably in his 50's, a stable and respected professor, and the girl is a college student, his new student and currently homeless status.  And he lets her stay in his private study/hideout space. 

For movies, try: My Teacher, Close Range Love, innocent Steps, P to JK
