I think it's clear Link has feelings for Saria. Just the way he interacts with her and how her being revealed as one of the Sages hits him. Hell, even the guidebook had a part where it said he put the Master Sword back in the stone after that moment so he could hang out with Saria in the forest before continuing his journey. I think that's pretty telling.

That said, I wanted to say Zelda at first, but then I realized those were my feelings, not Link's. Zelda is mine, hands off!
