''I thought people always remembered their first kiss.'' Katariina ''Katya'' Petrova grew up with Natalia Romanova in the same institute, trained to be a killer deadlier than anyone. What started as a friendship quickly turned into something more. There was only one problem: relationships were strictly forbidden. Upon betrayal, the girls were torn away from each other, never to be seen again. Until Natalia Romanova becomes SHIELD Agent Natasha Romanoff and stumbles, in the middle of a battlefield in Serbia, upon the girl she had pushed out of her mind. Only Katariina isn't a little fifteen-year-old girl anymore and hasn't found herself on the path of righteousness.
