You were Harry Potter's enemy because you were Draco Malfoy's brother so you always tease and annoy eachother that people think you two flirts or anything.

You both were in the courtyard, arguing quietly because there was people around and Harry was with a lollipop in his mouth and Hermione came to him.

"Can I talk to you for a sec?"

Hermione asked, making Harry turn around to face her and he took out his lollipop out of his mouth and give it to you.

"Hold this."

You hold it and while Hermione was speaking with Harry you put the lollipop in your mouth.. and when Hermione look at you her eyes widen and jaw dropped, making Harry look at you too and he start to blush, you just out his lollipop he gave you to hold and you put it in your mouth.
