It's nighttime at Hogwarts, it's past curfew. You had a doubt that hadn't left your head all day, so you went to the library and were thinking about going to the private session but what you weren't expecting that night was meeting Draco Malfoy (who was head boy that night and you didn't know).

"May I know what are you doing here, Berman? Don't you realize it's past curfew?" — Draco says seriously, but for some reason I was sweating.
