Help Please!?

Hey guys I need some help finding a yaoi manga that I can't remember the name of for the life of me. From what i remember one of my favorite parts was were a college students work got stolen by his own professor I believe. I think people either really didn't like him or he was so forgettable. Later at a conference, the guys BF goes to the conference and watches the professor present the stolen work and speaks up pointing out he really doen't know his stuff. Later another professor hires the guys whose stuff got stolen. I can't remember if it was a stand alone or was a multiple story manga and I believe the two dating might have had an age gap. Thanks so much!!(≧∀≦)
