I'm not a big supporter in the yaoi department but I guess there are shreds of evidence and this is the anime fandom...

I personally like to think of them all as straight people. Rin gets all pumped up to compete with Haru because they aren't normal "Oh do you want a popsicle,Haru?" friends,they're more like hardcore rivals(I guess that only applies to Rin but). And Makoto and Haru are neighbours and friends,so it's pretty normal for them to be close and know everything about each other.
