• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE.

"Do what? Do I ice her? Do I marry her? Which one of these?"
Prizzi's Honor

The Career Killer is as deadly as he is serious about his job, "Nothing Personal, it's just business" is their favorite quip for a reason. He can spend months infiltrating a target's life and winning their confidence without hesitating to pull the trigger once the order comes. Of course, there's always that one target... not The One That Got Away, but the one that got into their heart.

Love has a way of sniping even the coldest heart, and against all sanity and better judgement the hitman grows a heart. Maybe in the process of casing the target he (usually a he) may discover she's just an Innocent Bystander who saw too much, and his Badass Creed emphatically says to Never Hurt an Innocent. Then again, it may just be plain old messy love sprouting as some ineffable quality of the target strikes a long dormant chord in his heart. Of course, maybe they just have really good sex.

At first he'll make increasingly implausible excuses to his superiors at the assassin's guild to justify not killing his Love Interest, even protecting her from rival hitmen until ultimately they decide he's gone rogue and put a Contract on the Hitman. Interestingly, whenever this happens the hitman was usually going to be betrayed anyway either by the client or his organization, and the defection quite literally saves his life.

The former target cum Love Interest will of course be really freaked out once she finds out the man she loves wanted to kill her not days ago, but usually rolls with it surprisingly well and trusts the hitman with her life implicitly. A weird sort of Stockholm Syndrome can be said to affect both: though their love is genuine, the situation is eerily similar. It seems the old assassin's maxim "Don't get involved with the mark, it can get messy" is putting it mildly.

Another Moral Dilemma facing the Hitman with a Heart is just what exactly to do vis-a-vis his former colleagues and innocents. Now that he's essentially done a Gender Flipped High Heel Face Turn into at least being an Anti-Hero, he can't just kill anyone he pleases. The Love Interest usually insists on holding him to a more moral standard, and only killing those who attack them or betrayed them.

Examples of In Love with the Mark include:

Anime and Manga

  • Rethink your definition of "love", and you have Seishirou Sakurazuka from Tokyo Babylon and X 1999.
  • Crying Freeman has Emu Hino, who saw Yoh Hinomura for the first time right after he murdered one of his targets. She was singled out for death... but she and Yoh fell in love and ran away together.
  • Rolo in Code Geass develops a strong, genuine affection for Lelouch Lamperouge while posing as his younger brother to monitor him and saves his ass (which kills him).
  • Ironically played with in Rurouni Kenshin. Assassin Kenshin and Tomoe fall in love with each other. However, the mark is Kenshin, not Tomoe, who is a spy for Kenshin's Genre Savvy enemies, who intended to invoke this trope on purpose in order to use her as a hostage and lure Kenshin into a trap. She went along with it because Kenshin killed her boyfriend in the war, but he eventually became her Second Love.
  • In Risky Safety, the oni woman Kade was sent to assassinate one of the Momotaro men. He sensed her attack, blocked it...and then they saw each others' faces and fell in love. Much to their respective armies' dismay.
  • One episode of Noir has Kirika befriending a target. She kills him anyway.
  • El Cazador de la Bruja has an episode where Nadie and Elis meet a husband and wife running a restaurant. Turns out that the husband was originally hired to kill the woman, but fell in love with and married her instead.

  • Played with in Grosse Pointe Blank. The hitman is actually in love with his mark's daughter.
  • Aeon Flux. It's a Justified Trope because they were lovers in a past life.

  • The movie Portrait of a Hitman. I don't know about 'falling in love with' but he can't pull the trigger on her.
  • Undercover Brother. After falling in love with the title character, Penelope Snow (AKA White She Devil) can't go through with killing him.
  • In The Whole Nine Yards, Jill Saint-Claire is hired to kill Nicholas "Oz" Oseransky by Nick's wife. But as her plan to get close to Nick (in order to more easily kill him, of course) proceeds, she finds she likes him too much to actually go through with the hit. It's even lampshaded in a conversation between Jill and fellow hit-man Jimmy "The Tulip" Tudesky:

 Jimmy: "Oz, you are the most chivalrous guy I've ever met."

Jill: "Do you see why I couldn't kill him?"

Jimmy: "Yeah... I love him!"

    • When Jimmy is supposed to kill Oz, he can't do it either.
      • In fact, he ends up killing a friend, another hitman, instead, although there are pragmatic reasons for that as well (he knew Frankie would betray him eventually).
  • Prizzi's Honor.
  • Wild Target, he is initially unable due to chance to kill her, but later he is bemused by her eccentricities and eventually falls in love and marries her.
  • This occurs off-camera in the movie Conspiracy Theory

  • The tale of Amor and Psyche, a story-within-a-story in the Metamorphoses by the Roman author Apuleius (2nd century A.D.), makes this trope Older Than Feudalism at least.
  • Cawti from Steven Brust's novels was a highly skilled assassin, who was hired to kill Vlad Taltos (she succeeded, but he got better) and ended up marrying him.
  • Dianora from Tigana plans her entire life out to kill Brandin for destroying her hometown and removing its name from people's minds, but when she finally manages to make it to his harem, and into his bed, she can't go through with it because she loves him desperately.

  • In Corrupting Dr Nice by John Kessel, grifter Genevieve falls in love with Owen, the wealthy but naive biologist whose pet dinosaur she and her father are trying to steal. Subverted in that he rejects her when he finds out what her profession is. As revenge, she woos him all over again under a false identity, then does everything in her power to hurt him after they're married.
  • In Death series: Averted. Memory In Death has Eve Dallas finding out thing Bobby Lombard married Marnie Ralston, who was pretending to be Zannah. Marnie only married him because she was trying to hurt his mother Trudy Lombard as well as steal her stuff. Then she impulsively killed Trudy, tried to cover it up, as well as attempting to kill Bobbie for kicks. Eve has to tell Bobbie about all this, and warns him that she will use this trope to manipulate him. Naturally, he is unable or unwilling to believe what she's telling him.

Video Games

  • XIII has one (female) assassin tell XIII that the #1 rule for assassins is not to fraternize with the target, so as not to hesitate at the time of killing. Which of course doesn't stop her from sleeping with him.
  • In Dragon Age, Zevran is a potential romance option if you spare him after his failed assassination attempt. Justified because it's just business to him and his employers will kill him for failing his mission no matter what he does, so he has no ill will against you.
    • In one of his first missions for the Crows, Zevran ended up sleeping with the Mark. While he didn't fall in love her she had convinced him to talk to his employers about her. Instead she tripped and fell on her head, killing her instantly. Zevran was applauded for making it look like an accident. He wasn't too cut-up about it, as he discovered afterwards she had planned on double-crossing him.
  • Visas Marr in Knights of the Old Republic 2 joins your party after failing to assassinate you. She is a possible love interest for a male character (though the Handmaiden becomes inordinately jealous).

  • In Sacred, two of the PCs, the Dark Elf assassin and Wood Elf ranger, are lovers. The Dark Elf was supposed to murder the Wood Elf as a rite of passage, but his love for her turns him into a Defector From Decadence.

Web Comics

  • In Order of the Stick's, the half-orc ninja Therkla is ordered by Lord Kubota to kill Elan (in order to get at Hinjo, for whom Elan is currently working as a bodyguard). Therkla instead develops a crush on Elan, defects, and is ultimately killed by Lord Kubota. Elan is unable to prevent this, and takes it kind of hard.

Western Animation

  • Something like this is used in The Zeta Project, but it's not romantic love. Zeta is a literal emotionless robot who is designed to infiltrate and eliminate targets without their being aware of the deception. However, after impersonating a man for months, Zeta bonds with the family and develops a heart. Deciding he doesn't want to deny the man a chance to see his daughter grow up (or indeed hurt any living thing again), he abandons the mission and goes on the run. This kicks off the main plot.
  • In Disney's Hercules, Megara aka Meg was set as a Honey Trap for the titular character by the Big Bad Hades. She went along with it because she had made a Deal with the Devil with him beforehand, and because due to her past she had lost all her faith in love. However, as she sees that Hercules is a genuinely kind person, she fell in love with him for real.
