My Life as Fanfic

The last two-ish years of life in my immediate social group has been pretty weird. Full of improbably cool events, exaggerated drama, and unlikely romantic developments.

Obvious conclusion: I am living in someone's fanfic.

So the question is, what was our original cannon? Do we resemble it at all, or has the author gone crazy? Who were the main characters? Could it be a crossover fic? And most importantly, who is the Mary Sue?
