Dio, your 'rival' or atleast that's what he called the both of you. He always tried to beat you at everything, and annoy you since you were also a top student.

Dio sat in the lecture hall as the professor talked about something. He was quite bored and noticed you a few seats infront of him. Dio grabbed a piece of paper and wrote a small note, crunching it up and throwing it at your head. He smirked and winked at you as you turned around.
