Recently I have been forgetting the names of so many manga. Anyway the manga is about a guy that goes to university and becomes the assistant to a professor that studies plants. They get along but the guy falls in love with the professor and quits. When they meet again, they become a couple. There is also a oneshot about a guy that can see fish when people fall asleep.

Sorry this is all I remember but I hope it helps.

Thanks. I tried to look for it in advanced search, but I didn't know it was a shounen-ai not yaoi.
