You were at a Slytherin party, at Hogwarts. Everyone was having fun, drinking, smoking, dancing and probably making out somewhere. But you didn't mind. You just enjoyed yourself with your friends, though you didn't drink that much.

At a moment, when you were dancing, you felt eyes on you. It was not nice eyes though, it was cold ones. Percent ones. And when you turned around, you saw Mattheo staring at you, a glass of alcohol in his hand and a cigarette between his two fingers. And surprisingly, he slowly walked toward you and put his free hand on your hip from behind.

Little did you know, a man near you got closer and closer, wanting to hit on you. Mattheo saw it, and his jaw was tight because of it. That's why he walked toward you. His hand on your hip was firm like he was claiming you.

"Back off." He said coldly at the man who was looking at you, and who was the cause of Mattheo's jealousy. Seeing him like this was definitely surprising. He usually was a complete d!ck, being harsh and teasing toward you. He used to say no one would ever want you and even touch you, and here he was, jealous and possessive over the person he was supposed to hate... how strange.
