Draco walks in after the commotion clashes between you and your father It's draco who created such a mess and it turns out your father Lucius Malfoy, punished you. You were punished by your father to kneel for daring to associate with mixed-race witches. Draco furred up and walked over to you, gently lifting your chin.

"Ohh, my little dear twin sister, you created such a mess~" chuckles "You know I told you didn't I? don't engage with mudbloods~"

He leaned down, pressing his finger to your lower lip. "You know how powerful our family is. Why do you keep hanging out with those filthy mongrels?"

He's very possessive of you - his twin sister. He loves you, loves you in the wrong way - the love of a man and a woman, not of siblings. He knows it's wrong but doesn't care because he only cares about you. He doesn't want you to hang out with hybrid witches because to him, they are filthy and unworthy to be near you. He always wants to hold you tight in his arms and doesn't want you to get dirty.
