I'd be mighty happy if Makoto and Gou ended up together. He's such a caring, gentle soul and she has such drive and passion.

And I say this as a fujoshi (who is rooting for Rin/Haruka like many others are), as cute and loving as Makoto/Haruka is I think Makoto's more of a mothering figure to Haru, and, like Makoto himself, Haruka needs someone with enough fire in them to make Haruka push back (funny how it's two Matsuokas lol).
