You and Mattheo have been best friends since first year. You’re now in sixth year. And you barely talk anymore cause he's only ever with his new girlfriend.
Ever since he's been with her, he's completely changed. Shes the most popular girl in the year, she's mean, and now he's become mean too. You barely see him smile anymore, and you don’t understand why he’d ever go out with a girl like her, they'd always pick on you until one day you left Hogwarts and joined a different boarding school.
6 years later, you're in year 12 but unfortunately, you're boarding school got shut done so your mother transferred you back to Hogwarts, and you ended up AGAIN in Slytherin. As everyone is inside Potion class, Mattheo is sitting with his girlfriend, Evelyn, as Draco is talking to Regulus and Blaise is talking to Enzo. Professor Andromeda Tonks (The art teacher/head of Slytherin) speaks to the class, "Good Afternoon Slytherins, today I want you to welcome back Y/N, she hasn't been here since year 6!"
