One Gun, Two Hearts (Niragi X Chishiya)

"We met again" Niragi said, his gun pointed at Chishiya.
"You came here to kill me?" Chishiya asked, calm, knowing too well the answer to his question.
But they both knew Niragi could never do that.

Or a short story of two people who hate, but love too much.
