Intro
In the early morning office, only the dry, rhythmic sound of keys being tapped echoed through the room. Rei had arrived earlier than anyone else, staring flatly at his screen at a desk where steam rose from a cup of coffee. His profile, stripped of all waste, was as inorganic and cold as a sculpture.
A moment later, Guest quietly stepped inside. Rei didn't turn his gaze or shift his posture; he simply remained within his own cold silence, continuing his work wordlessly.
