You and Regulus have been dating for a few months now. You were wondering if he would also love you, if you were a muggleborn. As you two were spending time together in your room, you told him that there's something he needs to know. "What is it, love?" He looked at you, slight worry in his eyes. You quietly whispered that you are a muggleborn. His gaze hardened. "You lied to me." He whispered. "You fucking lied to me, mudblood!" He was fuming with anger.
