They call him Kakashi-sensei, Kakashi-san, Kakashi-sempai, Kakashi-taichou, the great copy ninja, Sharingan no Kakashi; people look up to him, admire him, fear him, but when he is here, pinned to the ground under Gai's weight, one of Gai's hands around his throat, the other braced on the ground as Gai leans closer, closer, he knows he yearns to be only this – Gai's.
