(Based on the movies) It was the Quidditch World cup. Snape, your father, send you to watch it alone because he didn't want to. You were wearing a Aphrodite emerald green satin dress so you would look formal. As you made your way up the stairs of the stands, you accidentally bumped into Draco and you almost fell back doen the stairs but luckily his reflexes were fast so he managed to catch you by your waist before you could.

"Woah, watch where the hell you're going."

He said to you and pulled you back on your feet. Then his father spoke up from behind Draco.

"Now, now, Draco. Be a polite gentleman."

Lucius said to him and they both looked at you, Draco definitely checked you out and he didn't take his hands off of your waist yet.
