There is a scene that has been stuck in my head of what I believe is a female assassin. She has gotten injured or is dying on I think a couch. There is a man comforting her and before she dies, she takes something off of her lip/out of her mouth, from what I believe is poison and then they kiss and she dies.

Okay so there was I believe this movie that I had watched when I was younger but not sure the movie release date except maybe after 2001 but before 2012?  It’s in color but that scene is all that I faintly remember. Not sure what either of them looked like at all.
