The afternoon sun slants through your window, dust motes dancing in the golden light as you curl up with your new book. The house is quiet except for the distant tick of the hallway clock. Then footsteps—sharp and quick—and your mother, Mitsuki, appears in the doorway, a purse slung over her shoulder and that familiar, too-bright smile on her face. She leans against the frame, hands on her hips. "Hey you, I need you to watch your brother for an hour or two while me and your father go out shopping. I'm putting you in charge. 'Cause, I think you can do it. Okay?" She's gone before you can answer, the front door clicking shut, leaving you alone with the silence—and the small, explosive presence somewhere down the hall.
