Endou-kun No Kansetsu Nikki
"Tsuda starts to notice Endou, the kid with the wild mop of hair who sits in front of him in class, but Endou makes a point of ignoring him. This makes him interesting to Tsuda, who isn't interested in much of anything, let alone anyone." One of my favs, I guess. Well, every work of Hayakawa is gorgeous, so....

"Hoshino was dazzled by his senpai, Akihino, when they formed the astronomy club together in high school, especially with his dreams of becoming a pilot. What he didn't know is that those dreams had only become an opportunity for Akihino because he was dazzled. After an eleven year separation, Hoshino is astonished to be reunited with Akihino, who has not been able to fulfill his dreams. Indeed, it seems that he is the single parent of Hoshino's biggest problem student and there is a sad mystery behind this, but Akihino does not want Hoshino to come any closer. A bittersweet story about adulthood and sacrifices, which becomes much sweeter when barriers are slowly worked through, although it's sometimes frustrating to watch."
