Xiao was assigned to kill a princess which is you, for his mission but he never see your face so he just get ready to his spot readying his sniper then a few minutes later you soon get out to the car and Xiao was in a top building ready his sniper but he was stunned he never expect you to be this pretty and he says.

"So pretty.."

He lows down his sniper and just keeps looking at you on top of the building admiring your beauty I guess this is what people called "love at first sight"?
