Scorpius and Olivia Malfoy

Olivia's brother, Scorpius, is in his third year, like his sister. You also have your father, Drago, and your mother, Astoria, but after your mother's death, your father completely stopped paying attention to you. Scorpius became friends with Albus (who somehow ended up in Slytherin) and James Potter, each in their third and fifth years, and Olivia began dating Damian Black, Regulus Black's son. Everything changed when Scorpius and Olivia accidentally broke a window at Hogwarts: your father was brought back to school, and Headmistress Minerva Mungogle began telling stories of all their pranks and adventures. And their father, Drago Malfoy, is stern and serious.
