I remember literaly nothing about the main plot of the anime, but i have one part i can remember, it's about a girl which is a supportive character in the anime, who's like really mature for her age (she's in highschool, i think..) and she falls for her teacher (i'm pretty sure it was a teacher ><) and he keeps pushing her away but she always tries.
i also remember she cuts her hair at one point, and that they end up being together.
also remember that teacher smoked alot, and lived in one of those tiny apartments (like a dorm thing, the typical anime apartment).
I also know that it had little to do with the main plot of the anime but thats all i can remember, because i keep adding it up to lots of different animes i watched, and it never fits.
it really buggs me that i cant remember it, i went through a list of over 200 animes i watched and nothing.
i'm pretty positive its a slice of life, drama anime.
thanks in advance.
