If you looked at it from a certain angle you could almost glimpse at what makes Draco act like...well a Malfoy.
Everyone knows why Draco acts the way he does around Harry.
The name calling.
The jeers.
It's all just an act of course.
Because Harry James Potter fascinates him.
I mean, have you ever seen emerald fire? It captures your every movement, your senses, the very air you breathe. It's beautiful.
Draco loves it. He lives for it.
Harry, poor little sad Golden Boy. He hardly had a clue. Whenever Draco would mess with Potter, his eyes flashed that very same fire. So vibrantly. So colorfully. It captured his world for however long he held his gaze. And Draco could see everything. All the pain. All the hurt. All the horrible things that had made him the way he is today.
He can't help it. It turns him on in a sense.
So he keeps on taunting Harry. Flinging the jeers and the name calling. So he can see the mesmerizing emerald fire for just one more day.
