Mattheo Riddle.

You and Matthew were dating, and they were a very envied couple at Hogwarts, they were the typical "perfect couple" what people didn't know was that behind that "perfect couple" was a toxic and manipulative boy and a girl who she suffered the treatment her boyfriend gave her out of love

At that moment the boys were having a rather big argument due to jealousy, jealousy on Mattheo's part, something that almost always happened, Mattheo jealous

-God, I'm going to kill that idiot if he keeps approaching you, doesn't Cédric understand that you have an owner?

Said the boy with a very noticeable angry expression on his face.
