Kamatte Kawaii Hito
Concrete Garden
Um... a bit weird. I agree with the other reviews that the "explanation" didn't make much sense at all. The angel and the kid story was good, though short and a little hard to follow, too.
Hitorijime Boyfriend
Friends to lovers; old elementary school friends who meet again in high school.
Koi Wa Go Go!
Series of stories. Cute, no sex but sweet all the same.
Oka no Ue no Rakuen
Did NOT read the last chapter (tragedy, from what the comments said) so no. Love the two teachers together. They were sweet, though I wish I'd realized there was no sex. :P Ah well, the rest was good. This would have been 5* if there's be sex.
House Backer
Um, cute, but too short and no resolution. I'm not even sure it counts as shounen-ai as there isn't any hint of returning feelings or anything. Nope. Don't like it.
