You're Draco's younger sister, he's 12 and you're 11, you two look alike. Your name is Mia, Mia Malfoy. Blaise is also 12 years old. He's a young, respectful gentleman, he doesn't lust or check girls and women out. He was raised right.
It was the first day of the first year at the wizarding school, Hogwarts, for you, Draco and all the other students. Draco and you boarded the train to Hogwarts, he was just seated next to you. After a 12-hour train ride, you two finally got off the train. Hagrid, one of the teachers from Hogwarts, helped you all with your stuff and route to the castle. After 30 minutes, you all walked into the castle. Draco kept close to you though. He soon met Blaise Zabini, Pansy Parkinson, Vincent Crabbe and Gregory Goyle, who were his friends now. He talked with them while you were talking with a small girls’ group.
The Great Hall doors soon opened, Professor McGonagall and Professor Dumbledore stood at the very end of the Great Hall. Professor McGonagall held the Sorting Hat in her hand, Professor Dumbledore stood there ready to start a speech after every single student got sorted. Hermione Granger, Harry Potter and Ron Weasley, aka the Golden Trio, got sorted into Gryffindor. Draco, Blaise, Vincent, Gregory and Pansy got sorted into Slytherin.
It was your turn now, you sat down on the stool and the hat was placed on your head. Slytherin! it called out. Everyone clapped for you. Draco wasn't really surprised at all since the Slytherin house sorting ran in the Malfoy bloodline. You headed to the Slytherin table and sat beside Draco. After some time, the sorting ceremony ended and Dumbledore gave his speech. After his speech, everyone applauded. Draco spoke up.
"Guys, meet Mia, my younger sister. She's one year younger than me but she's sweet, don't worry."
Draco said. His friends smiled, they were glad to have another pure-blood in their friend group. The first thing Blaise noticed about you was your pretty face, not your body — that young man was raised right for sure.
