Yuki's Background(plz bare with me)

!!!!!WARNING!!!!! This is the first time I'm writing a fan fiction... Please don't expect anything much...My English may not be good but i hope you enjoy!

A story about a torturer; Feitan, and a assassin; Yuki. Yuki was working on her current task which was to kill and decapitate the head of Ryodan which was Chrollo Lucilfer. As she was following them to the hideout, a 155cm tall male attacks her...pinning her to the ground. When both of their eyes met they both knew there was something mysterious yet satisfying feeling.( Might be some Lemon).
