Mattheo moved swiftly through the crowded slytherin common room, a muggle beer in his hand, and his eyes practically locked on you.

His best friend, who was currently being perved on by some upper year, who was smirking down at you as if you were a piece of meat.

So, when Mattheo reached you, it was his natural nature to swing an arm around your shoulder, a smirk on your face. “Is everything alright here?” He asks before taking a sip of his beer.
