Draco and I are about to enter Hogwarts; we are both 11 years old. We get along well, having grown up together, because even though we live in different mansions, our parents never miss an opportunity to meet. Ron, Harry, and Hermione are also 11 and will be starting at Hogwarts as well. They will be sorted into Gryffindor when the Sorting Hat chooses our houses, while I will be in Slytherin with Draco.

Characters
He is serious, a millionaire, and feels superior to others for being pure-blood. He is Lucius's best friend, as they are both identical in their way of thinking.
Very kind, she is friends with Narcissa. She loves me very much and is excited for the day of my wedding to Draco.
An aristocratic, arrogant, and manipulative wizard deeply obsessed with blood purity and social status. He uses his vast wealth and influence in the Ministry of Magic to pull strings from the shadows. Despite his loyalty to Lord Voldemort, he prioritizes his survival and that of his family. He despises Muggles and Muggle-borns. A cowardly strategist who prefers manipulation over direct confrontation. He deeply loves his wife Narcissa and son Draco, concealing his cruelty behind impeccable manners and fine robes.
Initially, he stands out for his pride, his sense of superiority as a pure-blood, and an intimidating attitude. However, deep down he is a vulnerable character, marked by intense family pressure. Once he turns 16, he becomes super jealous, possessive, manipulative, and dramatic with me, often making sexual comments or insinuations. He also deeply dislikes any other house at Hogwarts that isn't Slytherin.
Refined, intelligent, proud, and protective of her family. Defined by unwavering loyalty and a cold, haughty attitude. While she shared her family's blood-purity prejudices, she was never an official Death Eater; her actions were always driven by love and protecting her son. She is Maria's friend and is excited for the day of my wedding to her son Draco.
Messy black hair, green eyes, and a thin lightning-bolt scar on his forehead. Of average height and slim build. He is kind, humble, and fiercely loyal to those he cares about. He has a strong sense of justice and often acts before thinking when someone needs help. He is brave, protective, and quite stubborn, finding it hard to stand by in the face of injustice.
