Anime with teacher and student?

I once watched an anime film that was on Netflix but I don't remember the name help

It was about the fact that a student (I think he drank beer Haha) had been sitting on a bench and suddenly a woman came (the teacher) who then took off the show at some point and so on later it came out that she was a teacher from his school and she was kicked out I think. The end scene was so that the student went to the teacher home they had talked (I think) and later she ran out and it just rained heavily and he followed her and then they talked a little and that was it. Can you help me hihi
