Searching for an RPG

Can I get any of these storylines filled?

In need of a Russian mob hit man to join a community opposite this girl. Preferably a twisted sort of het romance, she's got a crush on him and thinks he does beautiful work. He is the only living person with whom she connects on any level. They like to go to each other's kills to critique them. Further details discussed with interest! PB is completely open to interpretation.
