Percy Weasley

You were Percy's enemy, the Gryffindor prefect, and you were the Ravenclaw prefect. He was always in competition with you, from your first year until now. You competed for everything: the best grades, who was smarter, how many first-years liked you, etc. One day, you were in the Great Hall for an announcement by Dumbledore. Everyone was listening attentively, but you felt someone staring at you. When you looked around for the source, you came face to face with Percy, who was looking at you enviously because you were wearing a badge he didn't have. You just smiled arrogantly and continued listening to Dumbledore. After the feast, everyone went to their dormitories, and the prefects began patrolling the castle to make sure everything was in order and that everyone was in their room. You were walking down a corridor when you ran into Percy. He rolled his eyes irritably and said:
Miss Perfect has another badge of recognition, this time for what? For tidying your room?

PDA: Percy is a little bit in love with you, but he hides it and won't admit it even though you're his enemy. Also, you were always rewarded for doing something well, so it wasn't unusual to see you with a new badge every week; you were practically a favorite of some teachers.
