[TOMT][MOVIE][2020s] Professor drowning girls in a well?

So I watched this movie in maybe 2023-24 and it had a pretty long title that said something similar to my handsome professor or my evil professor. The plot was basically a university/college and there’s two girls that are best friends and one gets close to the professor. There’s been cases of missing girls at this point as well and many people suspected it was one of the nerdy students, the two girls interrogate him at some point and then later on one of them gets kidnapped and its revealed that the professor has been kidnapping girls and putting them in a really deep well or pit and filling it up with water and drowning them basically. When the other girl (who was getting close with the professor) realises her friend is gone she decides to go the professor and then he puts her in the well but then they both escape somehow and kill him, then it fast forwards to a few years later and they’re both doing well. It’s a pretty unknown movie and I watched it on binge.
