So let me get this straight..
Henri was dating Catherine
Catherine was secretly seeing Mathias (as she told Junie in the bathroom)
Henri was also secretly seeing Mathias..
But Mathias was in love with Martin, who is was also secretly seeing,
but he was dating Ester.
Unless I misread some of the subtitles, that's some crazy love interactions going on. Mathias is a PLAYA
Oh and I really liked the ending and the message it sends, but a huge part of me just wanted to see a love scene between the teacher and Junie. The sexual tension those two had doesn't even compare to any other movie. It was just incredible and phenomenally portrayed.
