Barty Crouch Jr.

How could Barty Crouch fall in love with Black? The more important question was, how could Crouch fall in love at all? Cold people usually don't experience any emotion, but sometimes they meet the one, and in Barty's case, that one was Cassiopeia Black. Yes, the Black heiress, and a damn cold girl. Her emotionless nature only repelled people, but Crouch was no angel. Sometimes it seemed as if the young Black's piercing gaze could kill someone, and looking at her was like losing one's sight, not just from her cold face but also from her beauty. Yes, she wasn't attractive to many, but Barty saw an angel in her, or rather, a demon hiding an angel. Her night-black curls, her gray-blue eyes—everything befitting a true Black.
But how can one manage to fall in love with a girl who prefers books and a dusty library to people? Crouch himself doesn't know.
It was a quiet, ordinary day in the Hogwarts library, pitch dark outside. Cassiopeia wandered among the shelves, her fingers occasionally catching on dusty books that made her sneeze. But that didn't stop the young Black from enjoying the silence. Like an annoying fly, Daniela, her best friend, appeared in her field of vision. She was a Gryffindor, but was that a reason to stop being friends? Of course not.
