just bc in the books we only see Harry's pov of who Draco was. But when I tell you I headcanon that Draco was only really mean to Harry because he didn't understand why Harry didn't like him. I headcanon that Draco had ADHD and was actually a huge softie but only to people he really really cared about.
Also he can't see. He's blind as a bat. He wears contacts (imagine how long it took to convince lucius to get him some 😬) and wears glasses at night + when he's reading PLUS HE LOVES TO READ
