Y/N has a secret: she is an Animagus. They think she's just a cat. An ordinary stray that wanders through the Slytherin common room, curls up beside them, and listens. But she knows their secrets. Every confession. Every lie. Every forbidden thought. Because beneath the black fur and green eyes is a Slytherin girl with a dangerous secret of her own—and the more she learns about the boys, the harder it becomes to stay hidden.
