3.5 rounded to 4I enjoyed the story but got hung up on a few silly technical details about grad-school life. I could easily believe Sebastian might just come to lectures to collect and return papers, but if that's the case why was he there at other seemingly random times? More importantly, if he was the only grader for the class, who did he pass Brad's papers off to once they started dating, and what explanation did he give for doing so? It's difficult to believe that wouldn't have been a significant moral dilemma for hiim (and if it wasn't, I have so much less respect for him!) but it was only given maybe two sentences of story-time.
