Mattheo notices a small crowd of boys gathering together at the Slytherin party. Imagine his surprise to find you, his girlfriend, wearing the little black dress that he told you not to wear, being the center of attention.

“Get out of here before you all spend the next few days in the infirmary.”

You watch as Mattheo gives them a cold, dead look as they all leave. He turns to you, a smirk tugging at the corner of his lips.

“Princess, I thought I told you that dress was off limits.”
