I too like the OP song. Not too crazy about the ED song though. I also love Discotheque from R+V. My iPod sees alot of that one, Toradora's OP/ED, Wagaya no Oinari-sama OP/ED, and a few from ef.
Just watched ep 12. Funny how this show can swing from hilarious to sad drama so fast heh. I like it, not complaining. The whole part at the school with the misinterpretations about Jin and Daitetsu were funny as hell, especially the confession from Honda then you have the sad ep 12. Can't wait for the closing ep to see how they wrap it up.
