Ato Hitoiki De Ai
Several stories about couples with serious communication issues. I was a little relieved when I finished the last chapter. After a while...guys, just talk with each other. Seriously. Especially the first couple. Three years in, the kid's trying to kiss you at every point, and you think he will be turned off by the fact that you're a guy? He?? KNOWS???
Inukei Danshi ni Natsukarechuu
A series of quick stories about silly people in love. Includes the bartender who is likened to a dog and others I can no longer remember.
Ubatte Choudai
A series of one-shots about men coming to terms with their attraction to other men. These are short but overall pretty satisfying!

Kaihatsu Muramura Mode
A series of PWPs mostly involving high school and college students. The most developed is a boy with a mole on his cheek and the best friend who teases it's his "yes" button. There's also teacher/student (I skipped it) and stepbrothers in love.
