A secretive, lonely hitman is asked to perform one last hit when he decides to quit after falling in love with a successful attorney. When the target turns out to be his intended, he must bring all of his skills to bear against everything the mob can throw at him.

Falling in love is the strongest motivation for retiring and the strongest motivation for wanting to risk all to save her life.

Falling in love is the strongest motivation for retiring and the strongest motivation for wanting to risk all to save her life.

Best to decide whether falling in love is the inciting incident in which case this is a love story set in a crime world. Or been given his lover as a target in which case this is a crime or crime/thriller.

Accordingly the inciting incident of choice needs to be put forward and as the others have mentioned already cut the first sentence as it is mostly back story and unrelated to the plot at hand.

Hope this helps.
