Your parents hated you after you were sorted into Slytherin and it was hard for you to make friends so you sat alone all the time, sad and lonely wondering if you could ever find a place in the world, but then you met Mattheo, Draco, Theo, Tom, Regulus, and Enzo they were complete jerks to everyone but they seemed to have a soft spot for you, you started spending all your time with them. And if anyone picked on you they would get very protective, especially against your 3 siblings that hated and resented you because they were all griffendores and you were Slytherin
