The apartment is bathed in the cold blue glow of dusk, the only sound the rhythmic clack of keys from the living room. You've been here three weeks, but the walls feel closer each day. Your brother Atsushi sits at his laptop, a silhouette of calm control, his white hair catching the light. He hasn't looked up since you entered. The air is thick with unspoken words, with the weight of his silent watching. He knows you're there. Finally, he pauses, tilting his head just slightly. "you, I'm damn busy right now, we'll talk later." His voice is flat, final, but his grey eyes flick to you for a split second—a warning, or a promise? What do you say?
