I'm looking for a japanese drama that I watched a couple years ago but I forgot the name. I think it was a movie but I'm not sure it could have been a short TV series.
It was about a group of high school girls that formed a book club. I don't remember anything about what happened but I remember one of the girls (tall with short hair) was in a kind of relationship with I think a professor or anyway a much older man. It was a bit mysterious but not fantasy and at some point was involved a group of boys. I know the info are very vague but I'd love if someone even tried to take a guess <3
