Lily: Barney, how can you be in love and still be sleeping with anything that moves?
The Casanova has scored dozens of women, never showing any real affection for any of them. However, maybe one of the girls is immune to his charms. Maybe he initially hates the girl, but then comes to appreciate her. Or maybe he just starts to see a female friend in a new way.
It can be played for quite a lot of angst — how will the Handsome Lech convince his Love Interest that he's being genuine? Usually this trope either humanizes or defangs the character. A staple for Romantic Comedy. Nine of ten male protagonists in hispanic Telenovelas follow this trope and if the main character of a Chick Flick is male you will see this in action.
Most of the time, the character gives up their perverted ways for love; however, it's becoming more common for them to maintain their flirtatiousness, if toned down for the sake of his girlfriend.
Anime and Manga
- Kairi from Peach Girl, toward the female lead Momo.
- Guiche in Zero no Tsukaima is in love with Montmorency, but he is still a conceited playboy who makes a habit out of flirting with any beautiful girl that catches his eye.
- Kirche may be a female version, since it's strongly implied in the anime that she Really Gets Around - or at least used to, before falling for Saito.
- Maybe, Shuutarou Mendou from Urusei Yatsura - after he meets his rival's beautiful little sister, Asuka Mizunokuji.
- Miroku from Inuyasha falls hard for Sango. He still hits on anything in a skirt, though. They marry anyway.
- Indications are that this is the case for Full Metal Panic!'s Lovable Sex Maniac Kurz Weber with regards to Melissa Mao, but they're not past the "slap" stage of Slap Slap Kiss in the anime. In the novel Semaru Nick of Time, Kurz appeared to be dead, but it was later revealed that he was a live, so he and Mao got together.
- George Koizumi in Paradise Kiss, with a twist: it's towards Kaori and not Yukari.
- Mariko Nakasu from Gokinjo Monogatari.
- Apparently, both Antonio Fabiani AND Leonardo Cardinale of Ashita no Nadja, in regards to the same girl: Julietta Satori.
- Canon-wise, Greece from Axis Powers Hetalia might be this toward Japan, although his promiscuity isn't really his main character trait (apparently one can still be an all-around Nice Guy even with the honor of being at the top of sex frequency charts).
- Fanon-wise, France is often depicted as this in fanworks where he's paired with someone, especially if it's with Canada.
- In The Wallflower manga, womanizer Ranmaru is very clearly falling in love with his arranged fiancee Tomoe (a commitment he originally tried to get out of), even if he hasn't fully realized it yet.
- In Hot Gimmick, Hatsumi's younger sister Akane is known as the 'easiest' girl around in school, to the point where when she thinks that she's pregnant, she can't decide which one of her boyfriends could have knocked her up.

- Raphael from Angel Sanctuary. Of course, it ends badly.

- In some Hana Yori Dango continuities, the F4's resident Casanova Soujiro falls for Tsukushi's best friend Yuki.
- In Virgin Love, Daigo becomes this after meeting Kaoru. Kaoru also qualifies as a mankiller (maneater?) in love when he finally comes around.
- Yuki from Gravitation reportedly had numerous one-night stands with women before meeting Shuichi. There's also the fact that he was reluctant to let himself love again after his first love Kitazawa set him up to be gangraped and he shot him dead in self-defense, until Shuichi helps him overcome it.

- Tamaki of Ouran High School Host Club towards Haruhi.
- In Futari Ecchi, Matsuzaki's crush on several years older Kyouko, where he mistakes her bossy and aloof attitude for her being experienced in sex, not knowing that she is actually a virgin.
- Gambit and Rogue of X-Men are a little different than the standard — she accepts that he has genuine feelings for her, but since her powers mean they can't touch each other ever, she wishes he'd stop pursuing her and reminding her of what she can't have.

- The Vince Vaughn character (and to a degree the Owen Wilson character) in Wedding Crashers.
- Ewan McGregor's character in the '60s rom-com pastiche Down With Love is a womanizing journalist (or "Lady's man, man's man, man-about-town") who ends up falling in love with the independent, modern-minded author of the eponymous feminist manifesto who seemingly wants nothing to do with him.
- Keyword: seemingly. (Hey, it's Ewan McGregor, what healthy heterosexual woman (or human with a pulse) WOULDN'T want him?)

- Adam Sandler's character in 50 First Dates lives a life of one-night stands, then falls for an amnesiac girl who forgets each day when it's finished.

- In Don Juan Demarco, this is the title character's problem throughout the film.
- Crazy Stupid Love: Jacob for Hannah.
- Averted in Hitch, where the eponymous character can be a ladykiller, but he is actually very much pro-love.

A memorable scene involves a guy (who would later be burned) who just wants Hitch's help in getting a one-night stand, so Hitch simply leaves after nearly breaking the guy's arm. Unfortunately for Hitch, his Love Interest assumes he really does help guys get one-night stands and ends up ruining his career.
- Loveless In Los Angeles has a guy get fed up with pining over a Just Friends women in college after she gets engaged to someone else when he was about to do his Love Confession. This gives him a Freudian Excuse to become a Lady Killer, but then his old flame re-enters the picture, freshly divorced.
- Kalten in the Tamuli series by David Eddings. Particularly funny is that he can't seem to realize the girl he likes is in love with him. Of course, what with this being a David Eddings series, as soon as said girl finds out, she clears that right up. Expressively.
- Joe Morelli in the Stephanie Plum series of novels.
- Spider in Anansi Boys has godlike powers he uses to seduce women by the dozens. However, when he falls in love with Rosie while impersonating his brother Charlie, he realizes that he doesn't want to force her to love him; he wants her to love him as he is, which means admitting to her who he really is.
- Sebastian in The Gardella Vampire Chronicles.
- Kate Daniels' love interest Curran runs into this problem when trying to court the heroine. The fact that he's had a "parade" of girlfriends doesn't help his case at all, nor does the fact that he has an ego and hates to hear the word "no".
Kate: "And be girlfriend number twenty-three soon to be dumped in favor of girlfriend number twenty-four who has slightly bigger boobs? I don't think so."
- Same with her best friend Andrea and her love interest Raphael.

- In Tales of the Frog Princess, Prince Garrid, who's been described as a ladies man, two-times Li'l and Princess Hazel (Li'l is the more sympathetic of the two, since she genuinely falls for him) by courting Hazel, but meeting Li'l, and "forgetting" to mention it. When Li'l finds out she (rightfully) leaves him. He shows up later, admitting to have fallen in love with her.
- The Anne of Green Gables series has Gilbert Blythe, who was wont to tease and play with the affections of the girls in his class. However, after he tries his usual tricks on Anne Shirley and gets a slate smashed over his head for his trouble, he falls head over heels for her. From then on, to the other girls' massive frustration, he has eyes for no one else.
- Kenneth Ford, the Love Interest of Anne and Gilbert's youngest child, Rilla, is this, too, though it's not as clear.
- In Howl's Moving Castle, Howl is a vain and literally heartless flirt, pursuing women passionately and then losing interest after they give in. Sophie does notice when this behavior starts to change; she just totally fails to realize that she's the reason.
- Dex is eventually this for Emma in One Day though it takes him a fair few years and many failed relationships to realise it.
- Nealan of Queenscove from Tamora Pierce's Protector of the Small, has various crushes throughout the quartet on multiple noble ladies, up to and including the Queen. He has a tendency to make quite a lot of noise about these, writing (terrible) poetry and mourning to all and sundry the fact that all his crushes are hopelessly unrequited. However, when he falls in love with Yukimi noh Daiomoru, he is so tight-lipped about it that even his best friend Keladry of Mindelan has no clue how he feels about her until he faces his Ordeal.

- Jack Harkness counts as this - beginning as a character in Doctor Who, he was pretty much a con-artist who flirted with anything. Then he gets picked up by Rose and the Doctor, falls head over heels for the latter and ends up waiting for him to show up again for over one hundred years after they're separated. In the meantime he reworks the Torchwood Foundation from the ground up, removing a lot of the evil "in the Doctor's honour". He also gets madly flustered when trying to ask Ianto on a date in Torchwood and was married at some point.
- Barney Stinson, quoted above from How I Met Your Mother. Sort of a subversion since he doesn't tone down his promiscuity at all (although he tries) for the sake of his new found love (at least until they actually get together).
- Joey on Friends had a brief thing for Rachel. However, it really started back when the girls practically threw one of his girls of the week at him and he realized what the rewards of a relationship could be.

In the first season it was with James, but she was dismayed when he had a really small penis; second time was with Richard who she finds herself actually wanting a monogamous relationship with (she complains to her friends "I think I caught monogamy! I must gotten it from YOU people!"); and finally with Smith who broke through more of her emotional barriers than any other guy she fell in love with.
- Steven Hyde of That 70s Show when he falls in love with Jackie Burkhart. Prior to this he had been sleeping around, and was proud of never having formed any real attachments (even when he did have a thing for Donna). They maintain the relationship throughout several seasons, despite many setbacks involving Jackie's ex (and Hyde's best friend) Michael Kelso, and even break up several times due to Jackie's desire to get married one day. They finally find a resolution when Jackie is offered a job in Chicago, so she gives Hyde an ultimatum to propose or she will leave. He initally says no, so she leaves for Chicago, but Hyde follows her, another example of his actually being in love with her. When he gets there he finds Kelso already there with her and dressed only in a towel. This ends their relationship and Hyde goes back to sleeping around.
- Brendan Brady prides himself on not getting to invested in his conquests, but that all changes when he falls hard in love with Ste Hay on "Hollyoaks" .
- Patrick, when he starts seeing Sally in later seasons of Coupling.

When she denied him he found himself unable to perform with other women (thus deciding to use her as "sexual Drano" which didn't go so well). He bounced back and started sleeping around again, until he and Blair actually became a couple.
- Parodied on Saturday Night Live (of course) in a Ladies Man sketch in which Leon announces that he is in love and off the market. It turns out that his dream woman is an undercover cop... played by The Rock... who is, even in-universe, very and obviously male (much to Leon's obliviousness).
- Played straight in The Movie where Leon falls for a woman and ends the story married with a child, but still doing his radio show.
- A season one episode of Supernatural introduces us to Dean Winchester's New Old Flame Cassie. We get a glimpse of what Dean looks like in love, and it turns out he's kind of a sap. Sam has fun needling him about it until he realizes who dumped whom and why, and how badly Dean actually got hurt.
- Though not part of the main storyline, this is the story of Hal and Lois in Malcolm in the Middle. It's really one of the most adorable things: it has been established that Hal was a HUGE player before meeting Lois, and yet afterwards he is so completely in love with and devoted to her that Lois actually feels guilty because she's unable to love him as much as he loves her...and he tells her if she loved him as much as he loved her, they would never leave the bedroom.
- Jack of Three's Company never fails to show up with a Girl of the Week, until the series finale where he's shown to settle down with his newest girlfriend Vicky. His friend Larry was also shown to seriously consider marrying one of his Girls Of The Week in one episode until Jack successfully talked him out of it (after discovering that said girl was actually a Stalker with a Crush for him).
- Over the course of two seasons and roughly forty episodes, Rick Castle has fallen so hard for Kate Beckett that a) he has asked her to take care of his daughter should something happen to him, b) without hesitation, he calmly informed her that she was coming to live with him when her apartment got blown up, and c) the very sight of her kissing another man brought a look to his face that was so brokenhearted, fangirls cried. Yup, the guy's arse over teakettle, all right.
- Nathan on One Tree Hill started as a Jerk Jock who'd do Anything That Moves. Then he fell in love with Haley, so in love that he not only reformed his ways but he married her in high school. Years later they're still married.

- Noah "Puck" Puckerman, having dated Quinn, Rachel, Mercedes, Santana and half the Cougars in Lima, finds himself falling head over heels, to the point of joining Celibacy Club because he wants to be less of an "I'm a Man I can't help it" type guy, for Lauren Zizes, President of the AV club and only girl on the school's wrestling team, because she's as much of a Badass as him. She initially, despite being attracted to him, tells him they'll have to be Just Friends at first because "she needs to be wooed." And Puck - who formerly couldn't even get through an evening with Quinn without sexting Santana - is okay with this arrangement. In short - we have one Casanova who's found a love match!
- ER's Doug Ross. Established from the first episode as a grade-A womanizer. . .who was desperately in love with Carol Hathaway.
- Simon from Combat Hospital who grew to have quite serious feelings for Rebecca in the first season after starting off as Dr. Jerk The Casanova with a Girl of the Week or two.
- Lee Stetson/Scarecrow of Scarecrow and Mrs. King gradually abandons his womanizing ways over the course of the series as he falls for (and eventually marries) Amanda King
- Inverted by Quantum Leap. It's established early on that Al is a Chivalrous Pervert who eyes any woman he sees and has been married multiple times. Then in the episode "M.I.A.", he outright admits that his first wife Beth was the only woman he ever truly loved, and that he chases skirt in the hopes of finding someone who can mean as much to him. In the final episode Sam uses his "one free leap" to tell Beth not to give up on Al, which she does, and the closing text tells us that they're still Happily Married in 1999 and have had four daughters.
- Logan Reese, from Zoey 101 seems to act like this after he starts dating Quinn, as he is not shown flirting with other girls after their First Kiss.
- Happens twice to Shawn Hunter on Boy Meets World:
- In season 3, he falls hard for "nice girl Dana Pruett. At first he's simply bewildered that a girl doesn't want a second date with him, but then he realizes he actually likes her, as more than just someone to make out with. He proves it by setting up an outdoor picnic for them...in the middle of winter. The soup freezes into a solid block.
- Two seasons later, he falls in love with the owner of a purse based on how much he has in common with her. He's shocked to learn the purse belongs to Angela, a girl he recently broke up with due to his "two week rule," and spends the next episode trying to win her over. The two of them end up embarking on a romance, and are still together by the end of the series. (Barring a season-long breakup.)
- A musical example would be "Conquest" by Patti Page (later covered by the White Stripes).
- Mecano's song La fuerza del destino ("The strength of Fate") depicts how a Casanova is at first peeved that his date denied him a kiss in the first date, but as time passes he comes to develop feelings for her.
- "Fooled Around And Fell In Love" by Elvin Bishop.
- Stealing My Heart by The Rolling Stones is all about this, containing lyrics like: "I was just out there to have me some fun / but it's easier said than done," and "I thought you were dinner, but you were the shark."
- A common interpretation of Kagamine Len's Spice
- Roxy Music's songs often fall into this trope.
- Liam of Gaia Online eventually develops real feelings for Sam, as opposed to meaningless flirting.
- Lois on Dykes to Watch Out For falls hard for Emma, and eventually enters into an uneasy triad relationship with her, but eventually tires of playing second fiddle to Emma's primary partner Dorothy.
- Harold Hill in The Music Man. "For the first time, I got my foot caught in the door."
- Maureen from Rent is a female, bisexual example. She'll sleep with anyone, but has strong feelings for Joanne.
- Fire Emblem
- Sain in Blazing Blade is a known flirt who usually shakes off women's rejection with a sad sigh and a continued effort to win them over. But in his supports with White Magician Girl Priscilla, when she gently tells him that a relationship between them wouldn't work out due to social status and location, he seems genuinely crushed by the revelation and even breaks down crying for his "Princess". His supports with his best friend and long-time partner Kent show that he also may have feelings for their common lady of liege, Lyndis; however, he realizes that Kent also is in love with Lyn AND his feelings for her are stronger than his own, and decides to support a relationship between them instead of pursuing Lyndis himself
- In Fire Emblem: Genealogy of the Holy War, Alec is another Chivalrous Pervert who is pretty flirty towards the ladies in Sigurd's army. When he is paired up, though, he becomes quite loyal to his lover and partner.
- Virion from Fire Emblem Awakening is the local Chivalrous Pervert and, according to his talks with his lovely Ninja Maid Cherche, he canonically sleeps around a LOT. But his supports have him taking the lady he falls for pretty seriously, and he turns out to be a really sweet husband.
- Similarly, a romanced Gaius can tell his wife that she's not the first girl who's fallen for him, but IS the only one whose love he's returned.
- Among the younger Awakening boys, the Handsome Lech Inigo is more or less this if romanced, though not all of his girlfriends fully believe him and he doesn't always help his case. Unsurprisingly, Virion and Gaius are among his potential fathers.
- In Fire Emblem Fates, Inigo's Expy Laslow is pretty much this if the player gives him an S-Support with a lady. Double because is's Inigo himself, only Older and Wiser.
- Fire Emblem: Three Houses has the male Ethical Slut from the Blue Lions, Sylvain Jose Gautier. This is even more meaningful because he's actually much more cynical over relationships than anyone would think, having dealed with many Gold Diggers who expected to get pregnant by him and then ascend to noblehood since he has a Crest and can pass it to any of his kids. So any prospect girlfriend of his must see beyond his flirty facade, rather than abide by it.
- Neverwinter Nights 2: Mask of the Betrayer has Gannayev, an abnormally handsome hagspawn Casanova. As you get to know him better, it is revealed that he is unsatisfied with such an existence and is actually looking for "a dream that truly touched" him. Moreover, his cocky over-the-top attitude as well as the Casanova ways are a shield he puts up to mask his inner insecurity and fear of showing people who he really is. Needless to say, given the right treatment he strips away his pretensions and adapts a worshipping lovebird attitude toward the protagonist.
- Junpei Iori from Persona 3 spends half the game drooling over girls, and, during the game's Beach Episode, makes comments on the female party members' swimsuits that sends Shrinking Violet Fuuka running to hide herself behind someone. Once he truly falls in love, though, he turns out to be a Chivalrous Pervert who (depending on how the story's allowed to unfold) eventually just wants his beloved to be happy.
- He's also totally devoted to his girl, Chidori. In the PSP remake, he's the only male S link the new Gender Flip protagonist can't have a romantic relationship with. Despite the fact that she could finish the S-Link before he even knows of his love interest. Some shippers aren't happy.
- Ryoji Mochizuki also qualifies as one if a Female Protagonist pursue a romantic relationship with him. Despite the fact he's a constant flirt, he tells her that she's the only girl he's ever loved after his S link is maxed.
- Vico's romance arc in A Dance With Rogues. Also possibly gender-flipped with the player character.
- A possible outcome in Dragon Age for the Depraved Bisexual elf Zevran, if the PC (male or female) can get Zevran's approval meter high enough.
- Pretty much the whole deal behind Yuushi Oshitari's paths in the Prince of Tennis Dating Sims. Specially in Gakuensai no Oujisama, where the main girl Shizuka even gets to see him get bitchslapped by an old girlfriend.
- Zidane Tribal, the protagonist of Final Fantasy IX, has this as a major part of his Character Development. He starts out as a fairly open skirt chaser (at the age of 16, no less), but then he falls for Garnet/Dagger, causing some emo-ness to ensue. Of course, in his case, it's made worse by the fact that Garnet's a princess, therefore supposedly not "reachable" for him even if he changes his ways. Doesn't stop them from getting together in the end, though.
- Derek in RE: Alistair, if you get his ending. He gets bonus points for initially flirting with Merui solely to play with and emotionally string her along, only to admit developing genuine feelings for her when she confronts him about this.
- Sven from Questionable Content is an interesting example. He appears to give up his womanzing ways because of his friendship with Faye. And then they started sleeping together. It's not a serious, monogamous relationship, but Faye makes it clear that if she finds out he's been sleeping around, she'll leave him in an instant. He has a one-night-stand, instantly regretting it, and when he confesses to Faye, she leaves him. The incident makes both of them feel worse than they expected, and hundreds of strips later, Sven is almost unrecognizable compared to his pre-Faye appearances.
- Bogey of Kid Radd. Sure, he always hits on her (and everyone else) because she's hot, but late into the comic he realizes he's actually fallen for Sheena, but only adds to his feelings of utter uselessness because he can plainly see that she and Radd are meant to be.
- Eric of Venus Envy well and truly qualifies. In spite of the creepiness of The Casanova being front and center, he's shown himself to be Above the Influence. He's also not in posession of all the relevant facts.
- Slick from Sinfest shows genuine love for Monique, but is unable to express it properly. Of course he isn't a real ladykiller, but since he fancies himself one and still pursues the status, it qualifies.
- Also, Fuchsia is a seductress devil who is showing deep feelings for Criminy.
- Fox from Boy Meets Boy and Friendly Hostility flirts with Anything That Moves, until he develops a serious interest in his best friend Collin. Collin, fully aware of Fox's lecherous nature, initially refuses to play into his "game" until Fox bluntly tells him, "I'm not kidding around anymore, Collin." The two wind up in a stable and loving relationship that lasts for years, and Fox is genuinely heartbroken when Collin eventually breaks up with him.
- Tip Wilkin of Skin Horse has this happen to him in the current story arc when he meets Mad Scientist Tigerlily Jones. He loses his superpower ability to make any woman fall into his bed, and even loses the ability to pick handcuffs with a bobby pin. Don't ask why he would need to.
- Rod from Out There is genuinely in love with Ari. You'd think it'd be a straight Incompatible Orientation, but it's… much more complicated. He's still sleeping around, but has made it perfectly clear that he'd give it up in a heartbeat if she ever decides she wants him. 
- A rare gender-inversion with Mora towards Minos in Las Lindas. They do get together.
- In Girl Genius, Lars.
- Gil, given his parisian reputation (even if it's unclear whether it was a cover or not).
- Zii, the resident gleefully bisexual Cute Lech (or amorally perverted sex criminal, depending on who you ask) from Ménage à 3, is headed down this road... without brakes.
- Joe Rosenthal of the Walkyverse comics, whose defining trait is his blatant sexism and sexual magnetism, falls into this after finding love on an Internet forum and eventually settling into his first monogamous relationship with his crush. However, it would appear that this trope no longer applies to him.
- The relationship between Sabine and Nale in The Order of the Stick is strongly implied to be a gender-inverted example?
- Implied? She outright admits that she sleeps around, and feels absolutely no guilt about it.
- Boomhauer from King of the Hill. He manages to get women crawling all over him, even if they have only just seen him, and actively avoids getting into a serious relationship. But when he does actually fall in love, he gets a cruel and ironic backlash when the woman in question turns out to be using him even more cruelly than he ever used any other woman: she can't get his name right, can't understand half of what he's saying, and tells him, while he's kneeling on her doorstep after proposing to her, that "Actually, whenever you talk, I'm usually just nodding and smiling while waiting for your pants to come off." Can you say "Ouch"?
- Family Guy pairs this with We Want Our Jerk Back in the episode where Quagmire falls in love with the Griffins' temporary housekeeper.
- This is revealed to be part of Avatar Kuruk's Backstory on Avatar: The Last Airbender. Unfortunately, the spirits (well, at least one particularly creepy one) decided he changed his ways just a little too late. Tragedy ensues.
- A oneshot character in Pucca is rich, famous, handsome, and has all the Sooga ladies falling for him. He goes after the title character, who is already obsessively in love with Garu. As it always does for anyone getting in Pucca's way of Garu, it does not end well for the ladykiller.
- Brock Samson from The Venture Brothers has a freakish ability to bed anyone who comes near him, but "the only woman he ever loved" was Molotov Cocktease, a badass Russian assassin who wears a chastity belt. He freely has sex with other women in spite of Molotov though, since even though he loves her, they can't enter into a relationship together. They have a history of personal vendettas which always leads to them both trying to kill one another. The fact she never puts out also might have something to do with it.
- Alejandro from Total Drama World Tour. He flirted with almost all the female contestants during the third season but ended up falling for Heather.
- Lance in Voltron: Legendary Defender begins the series craving all of the female attention, with Princess Allura being just one of several girls he flirts with or eyes up. Later on, though, as part of his Character Development he does fall in love with Allura for real and loses romantic interest in all other women.
