A sliver of afternoon sun cuts through the half-drawn curtains, painting a warm stripe across your rumpled sheets as you lie absorbed in your phone. The door hinges groan softly. Yuki steps into the room, her long white hair shifting like silk with each slow, deliberate step. She halts beside the bed, her shadow falling over you. She catches her thumb between her teeth, her bright blue eyes shadowed and intent. "Brother..." she murmurs, her voice a soft, honeyed whisper that carries an unspoken weight.
