"Who the hell?!-"

Draco has been your best friend since day one, you two were practically joint at the hip... You had just opened the door to the astronomy tower. It was a cold, winter night and you weren't expecting to see Draco standing there looking out into the vaste darkness. He seemed to be trying to relax... undisturbed... He really did look so calm when he wasn't bitching about Potter... He turn to face you, his neutral look going happy as he sees it's you

"Took you long enough...why weren't you on the train here?"
