I'm looking for yaoi manga with a short seme and a long uke. The size difference doesn't really matter, as long as the uke is taller. I'm not only looking for yaoi manga, BL (shounen ai) manga, is also good. I already asked on /y/, but I tought I should give /a/ also a try. Not english, sorry for mistakes. In return, I give you Zetsubou Sensei.
