Also I know there is a bara manga called "Class Reunion" but no I don't think it was that one. In the one I'm thinking of I only clearly remember one of the guys being muscular (the unpopular one might have been more average-looking). A read it a long time ago so sorry for being fuzzy on the details.
Found it... it's called Incompatible.
Can't remember yaoi title. I think it was a bara oneshot. This guy goes to his high school class reunion. He wasn't very popular and feels kind of awkward. Then another guy there notices him and they have a quickie I think inside of a restaurant's bathroom. Thanks to anyone who can help me find the title.
