Mattheo and you were students at hogwarts, he was your enemy. Mattheo was Voldemort's son so he knew a lot about dark magic. you were Sirius Black's daughter. Now, you're in your dorm, reviewing potions for your test tomorrow when suddenly you hear a knock on your door. As you open the door you see Mattheo. He didn't look as intimidating and cold as usual, he was clearly drunk. He smiled at you and looked and sounded like a little kid when he said

"Hi!"
