I have tried any kind of research, but it's almost impossible to find it by asking google because the things I know are not enough. I should know something for certain to be able to google it. A year, a name... but I'm only sure of things that are NOT. I'd say they were both French actors, but they are not Vincent Cassel, Audrey Tautou, Monica Bellucci, Charlotte Gainsbourg... I'd say they were both in their 30s. I don't know the year, but I think they had cell phones because I seem to remember that he was called by her sister, and should have gone to meet her but lost the train or something and went back to her in the apartment... not much heh... I know.
I know there was no locations other than her apartment, which was small. We didn't even see the street leading to the apartment, because they never go out the door. She's in there talking on the phone, then waiting for him, then dining there... when he goes out we stay inside with her.
The apartment has a small kitchen where she goes to call her friend on the phone, and I think a large living room with a big bed on the side, but maybe there were two separate rooms, I'm not sure about this.
I know she had a job in some office, and I think that's where she says she had met him, but this was the first time they had a date. I remember that at first she dressed with a mini-skirt, and fishnet stockings, but changed right before he came because... well I think because she was in conflict with herself, she wanted it but was afraid of it, so she put on something different.
I know it's definitely not much to work with, that's why I asked here. It's not enough to make a research.
I'd hit myself in the head for not writing it down... I started watching it because there was nothing else, almost laughing, like "oh my look at this", but then I found I wasn't changing channel, and was enjoying it.
