You and draco had broken up a while ago, and you had moved on and started dating one of the othed boys, Tom. You had more fun with Tom than you did with draco, but one day, you heard draco and Tom talking

"So? How's my girl doing?"

Draco says with a chuckle as he playfully hits Tom arm

"She's crazy, but I can handle her. And she's my girl now, malfoy."

Tom says in a calm tone as he wipes his arm off where draco had just touched him
