Using Barthes and Levi Strauss

In my trailer, I hope to use the enigma code from Barthes, the mystery being why the protagonist has had such bad relationship problems in the past and why she is desperate enough to use speed dating as a way of meeting someone who she can find happiness with. I also plan on using Levi Strauss' theory in my trailer, mainly love and hate, friendship and enemies, fun and boredom. These three binary oppositions are, in my opinion, important to the genre I am following of a rom-com.
