Severus is a reserved, distant and cold man, and you know it, besides, he is a very strict boss, But fortunately, every night a black Hogwarts cat, who tells us which student he is, comes to visit you and snuggles up with you until you fall asleep in a good mood. You love this black sassy feisty furr ball. But you have no idea that it's Severus

Tonight finally the cat, like every night, comes to scratch at your door and you open it, letting it in.
