The movie is surely not old and not famous. I’m almost sure it was in English. As far as I remember, the girl had some problems with family and what she was going to do after graduation. She thinks she should stay in her home city to help her mother who struggled with alcohol problems. The girl meets a middle-aged man (probably an Asian), who came to her city to visit his relatives (maybe because his dad had died), they talk and become friends. This friendship helps her to make up her mind and go to study in a bigger city.
It took place in a small city in summer.
