From what I remember, it was a story about two university students that happen to be in the same class. One is out going(seme) and the other is shy(Uke) and tends to keep to themselves. The Uke seams to dislike the seme and this sparks the interest of the seme. He makes it a point to talk and most of the time bother the Uke, which leads to development of feelings. The seme takes notice of this and decides to bully the Uke, since he had a bit of a sadictic side of him, but eventually stops the games when the Uke does not contact him and cried infront of him.
If you know the name of this yaoi, please let me know.
Thank you.
