Really wish there are more yaoi dj of Haru (uke) x Makoto (seme). Hiks... :(

I wish too... Did ya read Oyasumi Mae Secret (it's on this site). It's cute and has a bit of smut and comedy. It also has seme Makoto and cute uke Haru

There's also another one of the same pairing. It's AU I guess (I'm not sure because the setting of the doujin is that of the ending song, you know the one in the Sahara and all the dude wearing Arabian clothes and all). The summary goes like this: Haru finally gets water from Run and drinks it, but found out that instead of water he drank aphrodisiac. Makoto has to help him from getting the aphrodisiac out of his system.
I forgot the name of the doujinshi but right now I'm trying to find it.

There are a lot more Mako x Haru than Rin x Haru you can find them in myreadingmanga.info
