Ooooh, I read Aiteru Door as well and I loved it... the basic premise of it is so typical and cliche, but it manages to be such a wonderful read thanks to the lovely characters and the execution. I skimmed through the Saigo no Door volumes and I think I like Aiteru Door better. Scruffy semes ftw! XD (And it's interesting, I'd never heard of five o'clock shadow before but somehow I've come across it twice in these past two days. 0_o)

And I read that Silver Diamond fic recently as well and it was great. XD
