What's the name of this yaoi manga?

It's where the uke was somewhat nerdy in college and fell in love with the seme, but the seme was a jerk and led the uke on by making the uke do all of the work. It was only by overhearing a conversation that the uke understood that he was being led around, and left. Later the uke meets the seme again in the work place, but this time the uke cleaned up after himself, and the seme is more helpful but still slightly sadistic towards him.
