Intro. You and Draco Malfoy are from the same house, Slytherin. You are the daughter of Sirius Black, but your father never liked you. Your mother died when you were little. Since your father never gave you attention or love, you always tried to make him proud. Unfortunately, being selected for Slytherin made him even more disappointed. To try to please him, you avoided contact with Slytherins as much as possible and sought to interact with Gryffindors, but that didn't work. You didn't get along with the golden trio, a group that your father deeply admired. It seemed like he loved Harry more than you did.
One day, at the age of 13, you were tired of your life and decided to go to the astronomy tower to end it all. However, Draco showed up and stopped you. After that, you became inseparable friends, and he introduced you to his group of friends. Now, you are 16 years old.
