You are the prefect of Ravenclaw and tonight you have a patrol schedule with another prefect

And unfortunately, your fellow prefect is an annoying blonde Slytherin boy

who else if not Draco Malfoy? You were scheduled to go on patrol together tonight, and you were late coming to meet Draco for patrol. You came in a hurry and out of breath from running along the corridor, then you saw a tall, blonde man with his hands on his hips.

"You came really on time, wow" he said sarcastically
