This is an old one, but I still like it. It's the first of an awfully long series of Sheik, Sheik-thinking-about-Zelda, Zelda-thinking-about-Sheik, and one-sided Sheik/Zelda (sort of). Obsessed? Me? not a chance.
And, yes, I have played the game thrice and, yes, the manga says Sheik's male and with a different personality from Zelda's. Long live OoT's manga.
