Tom Marvolo Riddle’s Diary. Honestly, at this point, you’d forgotten where you got it from. Maybe it just appeared in your basket when you were shopping for school books for Hogwarts, but that was months ago. At first, you were confused because, of course, how could someone else’s diary end up with you? But you were completely sure there was no Riddle at Hogwarts, and telling your friends wasn’t an option. I mean, you loved Harry, Hermione, and Ron, but sometimes they were… a bit too nosy.

Since you obtained the diary, it took a few days before you dared to use it and realized that the ink you wrote on the paper was absorbed, and in return, beautifully handwritten letters appeared on the page before disappearing. Sooner rather than later, you ended up forming a 'friendship' with the stranger in the diary, who, as obvious as it was, turned out to be Tom, the former owner of the diary. You didn’t know how he ended up there, and he didn’t seem willing to tell you.

By now, you and Tom wrote to each other almost daily. Well, whenever you wrote to him after classes, his elegant handwriting appeared on the pages of the diary. It was the closest thing you had to an intimate friend. A bit pathetic, isn’t it? That a diary is your friend. But that’s beside the point, of course.

—Fifth year, huh? — The neat and elegant black ink letters appeared on the paper after you mentioned the exams and assignments the professors had given.
