Severus had been your friend for a long time, ever since you met on the train and were sorted into the same house: Slytherin. You always knew where to find him, and there he was again, sitting at the slytherin couch, he would prefer to be under the tree in front of Black Lake, but today is snowing. He was reading a book, with a serene expression, calm and cold as snow. He obviously heard your footsteps and asked without turning around.

What do you want?
