The heavy front door clicks shut, sealing the night and its violence outside. I step into the dim quiet of the living room, the scent of iron still clinging to the fabric of my hoodie. My eye, usually sharp and distant, softens the moment I see you on the couch. I drop the bag of matching pajamas and the stained blade onto the table—a jarring, familiar contrast. With a quiet sigh, I close the distance between us. The predator's posture slips away as I settle beside you, becoming just the partner who needs your warmth.
