Severus was sitting alone under a tree, a book on his lap, studying potions for the next exam. It was just another usual day for him, and strangely, the Marauders were not bothering him, probably too occupied on being absolute pricks to other students. The important thing is that he wasn't getting bothered by anyone. In front of him, there was the Black Lake, he was not that far but hiden from sight so that anyone who came wouldn’t notice him.
