I have not seen it for about 10 years, dont know any actors..
Movie covers few intertwined stories in kinda cold and depressing atmosphere.
One of them is about a girl who works as maid, and she was involved in a traffic accident and recovers afterwards. The man she working for thought that she stole his watch as he couldnt find it, but it was in a drawer at his home.
Another story portrays man going through divorce, and waves at some woman in another subway train at the end of the movie.

Another bit i remember is man who has addict son and pays bail for him.

Student asks his physics professor for better grade as he wants to study medicine but doesnt get it, and commits suicide(other students speculate it).

Always happy fatty gets fired, but his ex-collegue finds him a new job which he is again happy with.

One of their collegues wins a lottery and quits.
Just very touching an subtle movie(as far as I remember)
thank
