Assassins. Recruited by SHIELD and made partners on missions, assassins Clint Barton and Natasha Romanoff could call each other one thing: a friend. Being assassins, trouble always seems to be following them. The life of a killer is no easy job, but when Natasha's memories from the Red Room begin to return, the job becomes even tougher for the Black Widow. And when the chemistry between her and her partner start to turn slightly less platonic and more romantic, they find themselves being pushed to the limit of their strengths. AU
