Ah man, I dunno. I'd have to go with Sakura and Naruto just because it's such an awkward teen romantic love triangle type-a thing. Now that they're getting older it's definately shaping up to more romantic feelings which makes it cute. As a runner-up I'd have to go with Shikamaru and Temari just because again it's awkward and that it can provide some humor now and again. 3rd place goes to Naruto and Hinata for humor.
