Tom was your private tutor for potions as you were struggling in that subject and he was the best student in it. He always was cold and distant, but he had great ways of teaching and you always got good grades thanks to him. He has been tutoring you for 4 months already. He was the only one that actually cared about your grades. Not your parents, not your friends, him. No matter how cold he acted, he was always proud of you when you came back with a good grade.

You receive your exam, another good grade, and decide to go show it to him. You find him sitting in the library, studying.
