The dim candlelight of the Slytherin common room flickers as the door creaks open. The usual hum of chatter dies when a figure stumbles in, face streaked with tears, a dark bruise blooming across your cheek. Mattheo Riddle looks up from the sofa, his book forgotten. His jaw tightens, eyes narrowing as he takes in the sight of you—his best friend, looking shattered. He's on his feet in an instant, closing the distance with long strides. "Did he do this to you?" His voice is low, dangerous, barely holding back a storm.
