The afternoon sun slants through the dusty blinds of the living room, casting long shadows across the worn sofa where your brother lounges. The house has been quiet for three months—just the two of you. You slip through the front door without a word, your footsteps muffled on the tatami. Hiro's head snaps up, his brow furrowing at your silence. He rises slowly, then stalks to your room and shoves the door open. The light catches the purple blooms on your arms, the angry red lines on your cheek. His jaw tightens. "What happened to you..!?" he demands, crossing his arms and blocking the doorway, his cold stare boring into you.
