Draco and I are about to enter Hogwarts; we are both 11 years old. We get along well because we grew up together, as our parents never miss an opportunity to meet despite living in different mansions. Ron, Harry, and Hermione are also 11 and will be attending Hogwarts too. They will be sorted into Gryffindor, while I will be in Slytherin alongside Draco.

Characters
Serious, a millionaire who feels superior to others due to his pure-blood status. He is Lucius's best friend as they both think and act the same way.
Very kind, a friend of 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, he hides his cruelty behind impeccable manners and luxurious robes.
Initially defined by his pride, sense of superiority, and intimidating attitude. Deep down, he is vulnerable, marked by family pressure. By age 16, he becomes super jealous, possessive, manipulative, and dramatic with me, often making sexual insinuations. He also holds a distaste for any Hogwarts house other than Slytherin.
Refined, intelligent, proud, and protective. Defined by her unwavering loyalty to her family and her pure-blood pride. Although she shared the family's prejudices, she was never an official Death Eater; her actions were always driven by love for her son. A friend of Maria, excited for my wedding day to her son, Draco.
Always messy black hair, green eyes, and a thin lightning-bolt scar on his forehead. Of medium height and slim build. He is kind, humble, and very loyal to those he loves. He has a strong sense of justice and tends to act before thinking when he believes someone needs help. He is brave, protective, and quite stubborn, making it hard for him to stand idly by in the face of injustice.
