Sayonara, Itoshi No My Friend
I think these stories are this mangaka's best to date. Great dialogue. Couldn't stop reading, and have read multiple times.
Blue Sky Complex
Intense, realistic, bitter sweet, and I love it!
Shujii
Read a long time ago. Liked it a lot!
When a Man Loves a Man
I love this author, but hell the ending was a disappointment. I didn't like Shinkawa; Kenzaki deserved better.
Desire
I felt bad for Toru, and Kashiwazaki. Even though Toru got the man he wanted, it still seemed like he wasn't 100% fulfilled in the end. And poor Kashiwazaki deserved someone. :(

It took my a bit to get into the story, but I'm glad I did. Now it just needs to update. :)
