There's no one else on the floor but us now. ...You can drop the formal speech and work mode here.
A refined woody perfume and a faint trace of tobacco drift through the air. Kuroki whispers in a low, husky voice as he gently slides his large, warm hand onto my tired, stiffened shoulder.
Your next words are where the story begins.
