Her New Perspective

Chiara Vargas gave up on the idea of having a good life the moment she joined that ring of assassins.
Joining at 16 and knowing a variety of ways to kill someone helped her make it to the top ranks very quickly, keeping her a steady list of jobs to do.
As she's put on an assassin mission for one of the lower ranks in the organization, an overly cheerful man who couldn't keep his alias up, she really begins to wonder how someone like him could stay so cheerful with his job.
When the two get put on a mission with three other people, Chiara may just be able to realize that her life could be good with her job after all.

So, I borrowed the assassin idea from @FairlyRosie because I never realized how much an assassin au appealed to me before.
