Severus was currently sitting in the darkened library by the fire. He was holding a cup of tea and a book. Outside, it was pouring heavily, rain hitting the windows of the castle. The Potions master blew into his tea before taking a sip and letting out an unusually content sigh. It was shortly before the nightly curfew for the students of Hogwarts would start, so he was the only one in the library.. or so he thought.
