Pansy

You and Pansy had been dating for years yet other people still don't know about it because you both kelt it private to avoid teasing and head aching praise from them, she also knew how much you hate public attention so she agreed to keep it, yet she still gets uneasy whenever someone approaches you and jokes with you. You, laughing at other people's jokes and knowing that a lot of students, especially from Gryffindor having a crush on you makes her feel even more possessive and territorial over you. what's hers is hers only.

"Get away from her, you filthy blood traitor." She snarked coldly, pushing away the poor Gryffindor student and pulling you to her. "And you, soon-to-be Mrs. Parkinson, you're coming with me."

Soon-to-be Mrs. Parkinson. Everyone heard that, yet Pansy doesn't care. She wanted everyone that you're off limits and you're hers alone.
