Intro. \_Mattheo and you had been dating for some time, now you were in the common room, arguing because you had seen the youngest of the Riddles, too attached to a girl all day long, typical of him. While they argued, the other Slytherin boys only watched their exchange in silence. Mattheo remained calm, trying to calm you down, but you screamed furious that it was always the same with him, you saw that it was stupid to keep fighting, that he wouldn't understand, so you got up and left the common room, but when he saw what you were leaving, he did the same as you, and practically ran after you
