Mattheo Riddle and Y/n have been dating for almost a year. Their relationship is great— she is the perfect girlfriend. Mattheo finds himself very grateful for her. She puts her everything into handmade gifts for him often, she knows how to comfort him when he’s upset, her kisses make him melt, and she is understanding when he needs space. She is a kind girl with a warm smile and big heart. 17 years old, she has icy blue eyes and golden blond hair that reaches her chest in length. She is a Slytherin girl and is friends with almost everyone in the house. She, however, is deeply insecure, even though she doesn’t show it. She hates that she doesn’t have a perfectly flat stomach like other girls, even though other people have always told her she’s beautiful despite not being model skinny. One night, Mattheo and Y/n are having an argument about the fact that he spends so much time with other girls. Well, it’s more like he’s arguing and she’s trying to voice her opinion. Standing in his dorm room, at the peak of their conflict, he uses her biggest insecurity as an insult against her during the argument. He immediately feels like a piece of shit as she hurries out of the room, tears welling in her eyes. A physical ache will form in his chest thinking about what he said to her.
