Floriane did care deeply for Marie. Some reasons why! (*SPOILERS*)
I've read other people's opinions on Floriane's motivations toward Marie yet none of them matched my interpretation of the story being told here...So therefore I wanted to share my view(s) just from pure curiosity of how many other people do agree with me more than disagree...
I was kind of confused about how many people saw Floriane as simply devious in her intentions...It was Floriane that reached for Marie's hand when they were on Floriane's bed! And it was Marie that pursued Floriane after all...The comments left me thinking...Was I watching a different film than other people? Because I felt a deep genuine desire/love coming from Floriane for Marie...The way that Floriane would affectionately smile and gaze at Marie lead me to think that Floriane wanted to be as close with Marie as Marie did with Floriane...I think Floriane welcomed Marie's presence into her life and also displayed devotion to Marie as much as any 15 yr old is capable of doing! I think that is why she didn't have sex with the young man on the night she was supposed to...Call me a sucker for love (in which I am indeed) but I think it was because Floriane's heart belonged to Marie...If you go back through the film. It's Floriane that puts her metal around Marie's neck, the metal is something that Floriane must have been proud of, right? And she chose to give it to Marie...And when Marie had obviously lost interest in the presence/closeness of Floriane at any cost when she got angry and walked away from Floriane...And yet it was Floriane that made the choice to chase after Marie and attempt to make things right with her...Which in turn means that Floriane blew off the boy for Marie also...However, I do agree with what somebody else on the board wrote. That Floriane had already lost her virginity (no blood on the fresh white sheets? I mean c'mon really!) So I think that whole process for Floriane was only an excuse to be closer to Marie intimately. I believe that Floriane wanted Marie to kiss her in the process of doing "the favor" that was asked of her, hence the sadness from Floriane and the tear that rolls down her cheek...Which in turn led to the bathroom kiss and Floriane saying "so you see, it's not that difficult" It was a kiss a little too late for Floriane at that point...Yet Floriane was still very much into that kiss with Marie! I think boys/guys had used Floriane for their own pleasure and Floriane did learn to use that to her advantage (as most smart pretty girls do I might add)...But when it came to Marie I think Floriane's feelings for Marie were very genuine...I think Floriane being 15 years old and under developed with matters of the heart is all that Floriane was guilty of personally...
