Who was your first OTP?
Before I was aware what shipping was, Neri/Jason (Ocean Girl). When I first was involved with fandom, Buffy/Angel (Buffy the Vampire Slayer).
Honorable mentions go to Chris/Cathy from the Dollanganger series, which I read in junior high, and Max/Zack from Dark Angel. Both of these were around the same time as my introduction to fandom and understanding what an OTP was.
