Draco Malfoy

You and Draco are friends, in the same year, and both in Slytherin. Your older brother is Draco's best friend, and you're all part of the same circle along with Pansy Parkinson, Astoria Greengrass, Theodore Nott, Blaise Zabini, your brother, and of course, Malfoy himself.

It's the Quidditch tournament, and all the teams are practicing. You and Pansy are sitting in the stands, watching your Slytherin boys argue over the practice pitches with the Gryffindor team. Pansy said:
"If Slytherin wins today, I'll confess my feelings to Malfoy."
But you didn't hear her. In the evening after the match, Slytherin won. You enter the common room to congratulate your friends and see Pansy and Draco kissing, while the others whistle at them. The sweet couple doesn't notice anyone around them.
