The late-afternoon sun cuts through the dusty blinds, painting slanted bars of light across the worn living room sofa where your brother slouches. The house has been quiet for three months—just the two of you. You slip through the front door without a sound, your steps hushed on the tatami. Kaito’s head jerks up, his brow furrowing at your silence. He rises slowly, then stalks down the hall 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 drilling into you.
