[[caption-width-right:302:[[http://www.smbc-comics.com/index.php?db=comics&id=2161#comic Take notes]]. [[FunnyBackgroundEvent Guy on bottom left]] is apparently a {{Narcissist}}. [[SchmuckBait There are also some duplicate arrows.]]]]

{{Love Triangle}}s are stressful and often heartbreaking. Add five or ten more people to the mix, and instead they [[CrossesTheLineTwice become comedy]]: Characters A, B, C, and D all love character E, who might love any of them, but can't commit for reasons of honor or basic wishywashiness. There's also character F, who ''might'' love E, and whom he might love back, but they get on each other's nerves so it's hard to tell. Meanwhile, G is sweet on C while H and I both love A. Except on alternate Tuesdays, when H's [[TheIdiotFromOsaka third cousin from Osaka]] expresses her intent to marry Character F's dog, who has an odd thing for D…

You get the idea.

Many series have [[LoveChart official diagrams]] so the fans can keep track of the LoadsAndLoadsOfCharacters.

''Literature/TheSevenBasicPlots'' Christopher Booker uses this concept as his definition of the ''Comedy'' genre, only the point is that the CleaningUpRomanticLooseEnds isn't a shoehorn but the soul of the plot:

* Start with at least 3 ideal relationships;
* Each relationship is stymied because the people involved are:
##Fixated on the wrong partners and [[ObliviousToLove oblivious to the good ones]],
##[[CannotSpitItOut Failing to communicate]], and/or
##Suppressing their desires due to [[StarCrossedLovers other factors]] (e.g., [[IncestIsRelative taboos]], class distinctions, [[ParentalMarriageVeto family]] [[ArrangedMarriage pressures]], etc.).
* The Villain (or sometimes the Hero) is the source of the biggest road block, so
* Make him [[HeelFaceTurn repent]] ([[MyGodWhatHaveIDone dramatically]]), and then
* Everyone can cheerfully enter into the relationship they were meant to be in all along.

The Villain (or Hero) acts as a FisherKing, casting a darkness and confusion across all the relationships until his HeelFaceTurn, which frees up the main couple to get together and that, in turn, frees up everyone else.

The Love Dodecahedron[[note]]A dodecahedron being a geometric object with twelve faces (or for the TabletopGames enthusiast, a ''d12'').[[/note]] is a superset of the following tropes:

* TheUnwantedHarem
* LoveTriangle
* AllLoveIsUnrequited
* TriangRelations

Also, see GambitPileup, which is similar to this trope, but with gambits. Though Love Dodecahedra can be the cause of such pileups. The opposite of this is NoLovesIntersect. There are three kinds of stable Love Dodecahedra:
#[[NoRomanticResolution Everyone staying friends]]
#[[MarryThemAll Everyone marrying the hero]]
#[[DumpThemAll The hero abandoning his harem]]
Can also sometimes be resolved by SquaringTheLoveTriangle. Compare DatingDoSiDo, which is similar with the lots-of-tangled-up-relationships part but the relationships do not necessarily have to be in competition with each other. TangledFamilyTree can be considered a sister trope, and a Love Dodecahedron can turn into one of those if given enough time. Video games that care about such relationships may track them dynamically with RelationshipValues.

* LoveDodecahedron/WesternAnimation


[[folder:Comic Books]]
* The ''ComicBook/ScottPilgrim'' graphic novels are known for this. The inside back cover of the third book consists of [[LoveChart an absurdly complicated diagram detailing the relationships of all of the characters thus far]] (including such descriptors as "in a band with", "still likes" and "dating(?)") that is rendered obsolete before the end of the ''first chapter'' of the next book.
* ''Franchise/ArchieComics'' has the famous [[BettyAndVeronica Betty/Archie/Veronica triangle]]. However, Veronica also regularly dates Reggie, who keeps trying to date Midge, much to her boyfriend Moose's wrath. Other than Betty, Jughead mostly runs from girls, especially his constant admirer Ethel, who occasionally has to settle for Dilton. Then [[ThirdOptionLoveInterest Cheryl Blossom]] came along. They've all had countless one-time love interests. Chuck and Nancy have enough sense to keep out of this mess.
* After they turned it into a soap opera, the Franchise/ArchieComics ''Comicbook/SonicTheHedgehog'' series twisted Sonic's love life into a Gordian Knot: Originally hooked up with Sally Acorn, she got stuck ruling the country and shoved the relationship to the side to focus on her new duties, prompting Sonic to fall in with Mina Mongoose, starting a rivalry between the two women for Sonic's affection. He then started seeing Fiona Fox on the side, which not only pissed off Mina and Sally, but Tails, as well, who had a crush on her due to falling in love with a robotic duplicate created by Robotnik several years earlier (don't ask). Eventually, Mina got her own boyfriend, Sally got Sonic once again, and Tails got tossed into a brick wall by Fiona, who gave them all the finger to have a relationship with Sonic's [[EvilTwin evil clone]] from [[MirrorUniverse another universe]]. Sally later started dating Monkey Khan but broke it off due to her history with Sonic. And that's not even counting the mini-tangle between Antoine, Sally, Bunnie Rabbot, and Antoine's evil clone from the same universe Fiona's new beau comes from.
** In WesternAnimation/SonicSatAM, Sonic was [[OfficialCouple obviously officially coupled]] with Princess Sally Acorn. Thanks to AdaptationDecay, RuleOfDrama dictates that Sonic and Sally are one of these with each other and everyone else. As a result, the comic's writers have a tendency to [[OutOfCharacterMoment rewrite the canonical romance]] to make the highly complicated romance plots seen above. When Sally proposed that she and Sonic become a RulingCouple, UnfortunateImplications ensued: ''[[http://static.tvtropes.org/pmwiki/pub/images/sonic_is_sallys_consort.jpg she confirmed that Sonic is her]]'' ''[[HotConsort consort,]]'' thus making every one of those romances [[YourCheatingHeart adultery!]]
* ''ComicBook/XMen'':
** Almost every member of the X-Men has been in love with another member at some point. One of the more famous dodecahedrons: Wolverine loved Jean Grey, who loved Cyclops, who loved her back but married her clone Madelyne Pryor, who had an affair with Cyclops' brother Havok, who almost married Polaris but [[RunawayBride left her at the altar]] for Nurse Annie, who kissed Iceman, who was unaware that Northstar was secretly in love with him... For those less familiar with the complicated relationships under Xavier's roof, Uncannyxmen.net made a [[http://uncannyxmen.net/db/article/showquestion.asp?faq=4&fldAuto=189 flowchart]].
** In the early days when Jean was the only female on the team, all of the men were in love with her (yes, including Xavier, but nowadays it never gets mentioned). Warren and Scott were the only serious contenders for her affection. Scott is also well known for attracting telepaths, having serious relationships with Jean, Madelyne Pryor, and Emma Frost most recently. He was also mutually attracted to Psylocke, but nothing serious ever developed.
** Speaking of ComicBook/JeanGrey, her past counterpart in ''ComicBook/AllNewXMen'' has some complicated examples. None of them even worked out, somehow:
*** She and Teen Scott were in love until they got to the future. Now she's not so sure she wants him anymore given what she knows about who/what he grows up to be, while he's still smitten, thinking that their eventual wedding is "proof" they're supposed to be together.
*** She and Teen Hank kiss. She instigated it on top of that. The events of ''ComicBook/BattleOfTheAtom'' cause a little fallout, and they're still not sure what's going on between them.
*** She and Teen Angel have a moment when he catches her when she's falling.
*** She also seems to be attracted to Modern Scott, but he quickly says it can't ever happen. ''Ever''.
* Also, ComicBook/{{Daredevil}}, Hawkeye, and Comicbook/IronMan keep dating the same women. Daredevil dated Black Widow, who also dated Hawkeye ''and'' Iron Man, and Hawkeye slept with Echo who is another of Daredevil's ex-girlfriends, as was Heather Glenn who was involved with Iron Man for awhile, etc. Yet another DD ex, Typhoid Mary, once tricked Deadpool into sleeping with her. Iron Man, for his part, has had a plethora of ladyfriends including Emma Frost (Cyclops' current flame), She-Hulk, and the Wasp. Remember kids, when you kiss Tony Stark, you taste Galactus.
* ''ComicBook/StrangersInParadise'' begins with a LoveTriangle and then... [[SerialEscalation hooboy]]. Katchoo loves best friend [[GirlNextDoor Francine]] unrequitedly, then takes up with David because [[DoggedNiceGuy he has been in love with her for years]]. Then Francine, who had a crush on David, starts to sort-of [[IfItsYouItsOkay reciprocate Katchoo's feelings]]. [[TheDitz Casey]], unhappily married to Francine's ex-boyfriend [[{{Jerkass}} Freddie]] (who still loves Francine), falls in love with David [[LoveAtFirstSight at first sight]]. With their marriage on the rocks, Freddie pursues Francine while Casey pursues David and also Katchoo. Katchoo, unable to deal with [[DysfunctionJunction the issues of her past and family]], finally drives David away. Francine becomes engaged to Brad and then breaks off her engagement to be with Katchoo, but still cannot consummate the relationship, so a frustrated Katchoo sleeps with Casey on the side. When Francine discovers this she goes back to Brad. When confronted at gunpoint by Katchoo's sister Tambi (who insists that their two families produce an heir via David and Katchoo), David offers to produce a child with her in exchange for his life and Katchoo's release from the obligation, and after they attempt this Tambi secretly falls for David. David returns to marry Katchoo, but the two part amicably once she learns about Tambi ''and'' realizes she prefers women. Casey finally gets to shack up with David… then [[OneTrueThreesome Katchoo joins them so they can all be happy together]]. Eventually, [[spoiler: Francine leaves Brad for [[YourCheatingHeart cheating]] on her; David dies, leaving Casey to take up with Tambi, and Francine and Katchoo end up together for good. Freddie [[TheChewToy ends up alone.]]]].
* Jaimie and Gilbert Hernandez's ''ComicBook/LoveAndRockets'' features several of these, particularly Gilbert's ''Palomar'' stories which are influenced by Hispanic [[SoapOpera telenovelas]].
* Due to their decades of continuity, many Creator/MarvelComics series have dodecahedrons so complex you need a 3D model to keep track. For example, Johnny Storm of the ComicBook/FantasticFour romanced Crystal, but she married Quicksilver instead and they had a child. But Crystal also began an ill-fated romance with Dane Whitman, who was not only involved with Sersi but also hopelessly pining after Wasp. Wasp was the ex-wife of Hank Pym, had an ill-fated one-night-stand with Magneto (Quicksilver's father!) and briefly dated Tony Stark, aka Iron Man (see above). To top it off, Crystal is currently betrothed to Ronan the Accuser, ruler of the Kree, who was formerly romantically involved with Una-Rogg, who tried to seduce Genis-Vell, who... you get the idea. Due to various destructions, memory wipes and rebuilds, Marvel's Vision is a one-character love dodecahedron.
* There's some sort of bizare love-lust-hate-obsession dodecahedron going on between Daredevil, Elektra, Punisher, and Bullseye. Bullseye is obsessed with Daredevil (in the AU ''Daredevil Noir'' Daredevil actually falls in love with Bullseye's genderswapped counterpart) and Punisher. Punisher and Daredevil have some angry manpain UST going on. Elektra and Daredevil were in love, and she and Punisher are attracted to one another (in yet another AU, [[ComicBook/Marvel2099 the 2099 verse]], they had a daughter, Cassandra). Elektra and Bullseye's relationship can best be summed up by his quote to her: "''I love to see you bleed.''"
* In the ''ComicBook/TeenTitans'' comics, [[strike:Speedy]] [[strike:Arsenal]] Red Arrow is into [[strike:Wondergirl]] [[strike:Darkstar]] Donna Troy, who got married to Terry Long. Meanwhile, Starfire was once involved with, and still has feelings for, [[strike:Robin]] [[strike:Nightwing]] Dick Grayson, who's engaged to Barbara Gordon. Red Arrow also had a crush on Raven, who had a crush on [[strike:Kid Flash]] the Flash (who is now married to Linda, but had a relationship with three other women first), then one on Dick Grayson, and now one on Beast Boy (which she might be over now). Beast Boy had a crush on Terra, then on Starfire, and is now in love with Raven. Still not sure where [[strike:Aqualad]] Tempest stands in all this. Cyborg is the only one that was smart enough to stay out of this crap, or he would have, if not for his [[WillTheyOrWontThey ambiguous feelings for Sara Simms]]. Red Arrow has a daughter, whose mother is a [[DatingCatwoman psychopathic supervillain]].
* For a comic which is only a decade old, the ''ComicBook/UltimateSpiderMan'' (now ''Ultimate Comics: Spider-Man'') continuity has a pretty impressive one for Peter. Depending on how you count things, Peter's current love interests include Gwen, Mary Jane, Kitty, and [[spoiler:Johnny Storm]]. That's not mentioning the fact that Peter currently lives with Kitty's ex-boyfriend Bobby as well as Johnny, [[spoiler: who made out with his OppositeSexClone]]. Added into this is Felicia Hardy, who was rather blunt in her attempts to woo Peter until she realized he was [[{{Squick}} fifteen years old]].
* In ''ComicBook/QuantumAndWoody'', one develops between Quantum, Woody, Amy Fishbein, Tempest Sheridan, and Holly Williams. Just don't ask how the goat fits in...
* The basic premise of the Creator/DCComics title ''Young Heroes In Love''.

[[folder:Comic Strips]]
* ''ComicStrip/{{Peanuts}}'': Marcie loves either Charlie Brown or Peppermint Patty, who loves Charlie Brown, who loves the Little Red-Haired Girl. Woodstock loves (or at least is jealous of) Snoopy [[InterSpeciesRomance who loves]] Marcie. Then you have Lucy who loves Schroeder [[CargoShip who loves his piano]]. Sally loves Linus, who [[PrecociousCrush loves Ms. Othmar]] and/[[CargoShip or his blanket]].
** In the the earlier days, [[BrotherChuck Frieda]] loved Schroeder, and [[BrotherChuck Eudora]] loved Linus. Linus did eventually get over Miss Othmar and did have crushes on girls his own age (but not Sally). And in the '90s, Charlie Brown had a girlfriend/crush named Peggy Jean... this is so confusing... and nobody is over [[ToyShip the age of 10]].
* In ''ComicStrip/FlashGordon'', Flash loves Dale, Dale loves Flash, Ming loves Dale, Aura loves Flash, Barin loves Aura, Ming hates Flash, and everyone hates Ming. Eventually this straightens out when Aura shifts her affections to Barin, and Ming comes to hate Dale almost as much as he hates Flash. Other women such as Freya and Undina also find Flash attractive, which always makes their boyfriends mad at him.

[[folder:Fan Works]]
* ''Manga/Evangelion303'': Let's begin: [[OfficialCouple Asuka loves Shinji]]. [[HeroesWantRedheads Shinji and Jessika love Asuka]]. Mandy loves Jessika and Jessika loves her, too. Hikari and Toji love each other. Rei and Saburo love Kaworu. Kaworu may have feelings for rei and he no longer loves Saburo. Misato is dating Shinji's ex-wingmate, and her ex-boyfriend Kaji is about to show up in the doujin. Gendo and Ritsuko are lovers and it is unknown like Gendo's marriage to his deceased wife Yui disrupts their relationship...
* ''Fanfic/KyonBigDamnHero'': As of Chapter 31, Kyon is confirmed to have 7 girls with romantic feelings towards him. And ''yes'', Haruhi is among them, and [[spoiler:she's planning on a MarryThemAll [[{{Polyamory}} resolution]]]]. Bet you didn't see ''that'' one coming, did you?
* ''Fanfic/{{Seduction}}'': Marjani, who is an arranged engagement with Kurumi, is in love with Sarakshi. Who Tora also has a thing for. While Sarakshi doesn't seem to have romantic feelings for either, Linda seems to harbour some for Marjani [[spoiler:(As of Chapter 18, his engagement with Kurumi has been dissolved and they are... in a ''bit'' of a relationship)]] and Yuki seems to harbour some for Tora.
* ''Fanfic/TDWTReducksRedux'' seems to be developing a massive one: Ezekiel likes Bridgette, who's dating Geoff yet has ShipTease with Harold, who also has ShipTease with Lindsay even though he really likes Leshawna, who broke up with him because she likes Alejandro. Lindsay was dating Tyler, who looks like he'll eventually hook up with Gwen, who likes Duncan (who's dating Courtney) even though Cody still sort of likes her, and Sierra likes ''him''...
* In ''Fanfic/{{Ragnarok}}'' despite being a CelibateHero [[Manga/DeathNote Light]] has practically [[EvenTheGuysWantHim everyone chasing after him.]] Mello and Matt are in a relationship but Mello still engages in some uncomfortable flirting with Light and Mello and Matt make it clear they're open to a three-way. Light dated Takada in college, had a brief but happy affair with Stephen Loud a.k.a. Gevanni of the FBI, and he went on a single date with Mikami before realizing [[StalkerWithACrush how crazy he was and has been trying to avoid him ever since.]] Misa loves Light but they agree that they're BetterAsFriends. [[StalkerWithACrush Also L has been stalking Light for the past year and Light has been stalking L.]] Also Near gets all flustered around Gevanni and Sayu.
* The titular boys of ''Fanfic/TheBalladOfStootAndArgyle'', Terrance Stoot and Phillip Argyle, are unknowingly enmeshed in one of these. [[spoiler: Karen [=McCormick=] likes Terrance, who's in a trial relationship with and might be falling for Eric Cartman. Meanwhile, Phillip is in love with both Terrance and Bebe Stevens, and unknowingly has half the female student body fangirling over him.]] Add in the boys who might like those girls, and you've got a tangled web.
* The ''Fanfic/PoniesOfOlympus'' series has Spike ending up in the middle of one in ''Atlas Strongest Tournament''--he still has feelings for Rarity, but is also attracted to Ran Biao, who is [[OperationJealousy using him to hurt Rarity]], [[spoiler: who she has twisted feelings for, feelings Rarity is reluctantly starting to return, even while realizing she's in love with Spike, and on top of that, Scootaloo likes Spike too, and it's hinted he might feel the same way. And then Scales and Wavedancer get involved...]]
* ''Fanfic/MoonDaughter'' has Nico, Alabaster, and Hades all hitting on [[{{Mary Sue}} Flavia]]; meanwhile, Flavia starts out claiming she was in love with Luke and won't date ever again, but then crushes on Chiron, flirts with Nico, moves on to Alabaster, dumps him, then goes back to Nico, claiming he's her one true love. And then she moves on to [[Literature/PercyJacksonAndTheOlympians Percy]]...
* In ''Fanfic/OfWhiteTreesAndBlueRoses'', between Ashara Dayne, Barristan Selmy, Brandon and Eddard Stark. Like in canon, Barristan had his crush on Ashara.[[spoiler: Ashara had a crush on Brandon, and Eddard had a crush on her. Ashara rejected Eddard's feelings for her, while Brandon dropped Ashara faster than a hot potato after a one-night stand. However, he fathered a bastard.]]
* In ''[[http://archiveofourown.org/works/573263 The Other One]]'', [[Webcomic/{{Homestuck}} Eridan]] ponders the canon entanglements between himself, Feferi, Sollux, and Aradia, respectively. (Terezi/Karkat are the BetaCouple.)
--> It took every ounce of self control not to roll his head across the keyboard and let that serve as his response, a mess of mashed buttons and still-unresolved flushed feelings. Aradia was Sollux’s [[LoveTriangle other one]], he knew that. Or maybe a better way to put it was that she might be Sollux’s ''one'', which made ''Fef'' the other one, which made him hate that guy even more.
* Subverted in ''Fanfic/FlashFog'': {{Deuteragonist}} Pencil Pusher has a big crush on Fluttershy, who is implied to at least like him back. This excites [[ThinksLikeARomanceNovel Rarity]] and [[TomboyWithAGirlyStreak Rainbow Dash]] to the point that they [[ShipperOnDeck start meddling to try and get the two together]]--Rarity more than Rainbow Dash. Unfortunately, this backfires, resulting in Fluttershy and Twilight Sparkle thinking that it's ''Rarity & Rainbow Dash'' who have crushes on Pencil Pusher, which leads to Spike fearing Pencil Pusher could be a rival for Rarity. The subversion comes because, after a couple of chapters of setup, Spike openly talks to Pencil Pusher about Rarity and is corrected, whilst Applejack, upon hearing about the situation from Rarity and Rainbow Dash, [[CuttingTheKnot drags all four of the mares into a private room and tells Fluttershy about Pencil Pusher's crush and Rarity & Rainbow Jack's efforts to get Fluttershy to notice him]].
* ''Fanfic/TheDemesneOfTheReluctantTwilightSparkle'' slowly forms one around Twilight. The first chapter implies she has a crush on Big Mac [[AbortedArc (though that has not been mentioned since)]] and that Celestia in turn is attracted to Twilight. Then Twilight develops a crush on her assistant Golden Retriever and has to deal with [[TheTease Rainbow Dash]] [[spoiler:who is then implied to genuinely have a crush on Twilight herself. And then Golden expresses interest in Dash...]].
* ''Theatre/AVeryPotterMusical'':
** Pansy → Malfoy → Hermione ↔ Ron
** Ginny ↔ Harry → Cho → Cedric
** Umbrige → Dumbledore → Snape → Lily → James
** Bellatrix → Voldemort → Quirrel
* In ''WebVideo/DeathNoteTheAbridgedSeriesKpts4tv'' [[NoYay Ryuk is screwing Light]], [[VillainousCrush Light is in love with L,]] [[{{Yandere}} Misa stalks Light]], [[MamaBear Rem]] loves Misa and so did Gelus. Then during Light's [[spoiler: MemoryGambit]] he [[TransparentCloset went back into the closet]] and only worried about being a good boyfriend to Misa ([[TheBeard who he is dating for other reasons that he can no longer remember]]) Misa then goes on [[YourCheatingHeart to cheat on him]] with with Higuchi and Rem. Namikawa flirts with Light. L makes a passing mention of [[MemeticMolester Beyond Birthday]], Light suspected [[spoiler: incorrectly]] that L was screwing Matsuda, and meanwhile L shows no interest in anyone except for maybe [[CargoShip his snacks.]] Also, everyone but Light wants Misa (including Ryuk) and when Mello kidnaps Sayu, Mr. Yagami tries to get Mello to take Light as well. Ryuk was doing... ''something'' with [[CargoShip an apple]] and Mr. Yagami flirts with Ryuk. Also [[NoYay Demegawa]] declares his love for Kira, Ryuk takes to calling Matsuda "daddy", [[BlackComedyRape Aizawa and Mogi go off to to "violate Misa" and Matsda and Ide wish they could join in]], and Aizawa may or may not have gotten someone who may or may not be his daughter pregnant. [[spoiler: Osoreda molested Near.]] There's also Gevanni (or rather [[spoiler: Raye Penber]])/[[CargoShip Death Note]].
* ''FanFic/MyLittlePonyNakamaIsMagic'': Spike has a crush on Rarity. Rarity and Applejack both have a crush on Sanji, who has a crush on everyone including Nami, who has her eyes set on Luffy.
* ''FanFic/MiraculousLadybugVsTheForcesOfEvil'': Oh boy. Star Butterfly is crushing on Marco who used to be with [[spoiler: Jackie]] but broke up before the fic. Marco considers Star his best friend, but then Marco got attracted to Ladybug, who's actually Marinette. Marinette's primarily enamored of Adrian, but isn't against hearing Marco out later since she doesn't feel worthy of him. Adrian is Cat Noir who's into Ladybug (not knowing about her being Marinette), but he's also somewhat attracted to Star. Add into that Chloe being possessive of Adrien as her guy, and Marco thinking Star's still into Oskar Greason, and you've got a bit of a tangle of feelings to work through.

[[folder:Films -- Animation]]
* ''WesternAnimation/StrangeMagic'': [[DoggedNiceGuy Sunny]] likes [[PrincessClassic Dawn]] who likes a string of different boys but is eventually accidentally [[LovePotion love potioned]] to like [[EvilOverlord The Bog King]]. [[JerkAss Roland]] cheated on Marianne with an unnamed girl but tries getting her back. [[spoiler: [[WorthyOpponent The Bog King]] and [[BirdsOfAFeather Marianne]] fall in love, meshing the two [[LoveTriangle love triangles]] into a proper Love Dodecahedron.]]
* In Creator/GoldenFilms' take on ''Literature/TheLittleMermaid'', Stefan falls in love with the mermaid-turned-human Lena, but his father has arranged for him to marry Anna, the girl who found him on the shore and brought him to medical care, except ''she'' is in love with a guy named Maxwell, which results in Anna marrying him and Lena marrying Stefan, [[SparedByTheAdaptation saving her from the fate of her literary counterpart.]]

[[folder:Films -- Live-Action]]
* ''Film/TheresSomethingAboutMary'' features a Type 3 [[TriangRelations Triang Relation]] extended into a Love Dodecahedron with Mary at the center. Everybody is in love with/stalks Mary, including the main character and football star Brett Favre. Naturally, Mary chooses the main character over Brett. (She's a Niners fan.)
* ''Film/{{Tootsie}}'' has a great example of this:[[note]]"Dorothy" is Michael's drag alter ego[[/note]]
-->'''Michael:''' You should have seen the look on her face when she thought I was a lesbian.\\
'''George:''' "Lesbian"? You just said gay.\\
'''Michael:''' No, no, no--''Sandy'' thinks I'm gay, ''Julie'' thinks I'm a lesbian.\\
'''George:''' I thought Dorothy was supposed to be straight?\\
'''Michael:''' Dorothy ''is'' straight. Tonight Les, the sweetest, nicest man in the world asked me to marry him.\\
'''George:''' A guy named Les wants ''you'' to marry him?\\
'''Michael:''' No, no, no -- he wants to marry Dorothy.\\
'''George:''' Does he know she's a lesbian?\\
'''Michael:''' Dorothy's ''not'' a lesbian.\\
'''George:''' I know that, does ''he'' know that?\\
'''Michael:''' Know ''what?''\\
'''George:''' That, er, I... I don't know.
* The 1982 avant-garde movie ''Film/{{Querelle}}'' has a complicated and bizarre love-lust-hate dodecahedron. The main character, Querelle, is attracted to the madame Lysiane, who is the mistress of his brother Robert. But Querelle first purposefully loses a bet to Lysiane's husband, Nono, and has sex with him as payment before becoming Lysiane's lover. Querelle also sleeps with Nono's friend, the corrupt police captain Mario. Meanwhile, a construction worker named Gil (confusingly played by the same actor who plays Querelle's brother Robert) murders his co-worker Theo, who has been sexually assaulting him. Roger, who is in love with Gil, introduces him to Querelle hoping that Querelle can help Gil escape. Instead, Querelle begins an affair with Gil but betrays him to the police. In the end, Querelle sails off into the sunse with his superior officer, Lt. Seblon, who has been obsessed with him the entire movie. So the Dodecahedron looks something like: Robert loves Lysiane who is married to Nono but who has an affair with Querelle, who also has sex with Nono, Mario, and Gil. Roger is in love with Gil, but loses him to Querelle. Seblon is attracted to Querelle and gets him in the end.
* Spoofed towards the end of Woody Allen's ''Film/LoveAndDeath'':
-->'''Natasha:''' It's a very complicated situation, Cousin Sonja. I'm in love with Alexei. He loves Alicia. Alicia is having an affair with Lev. Lev loves Tatiana. Tatiana loves Simkin. Simkin loves me. I love Simkin, but in a different way than Alexei. Alexei loves Tatiana like a sister. Tatiana’s sister loves Trigorin like a brother. Trigorin’s brother is having an affair with my sister, whom he likes physically but not spiritually.\\
'''Sonja:''' Natasha... It's getting a little late.\\
'''Natasha:''' The firm of Mishkin and Mishkin is sleeping with the firm of Taskov and Taskov!
* ''Film/CrazyStupidLove'': Robbie has a thing for his babysitter Jessica who has a crush on Robbie's father Cal who is going through a really rocky relationship with Emily, who had a one-night stand with David [[spoiler: but is also the mother of]] Hannah, who's the girlfriend of Jacob, who teaches Cal how to "regain his manlihood," which allows him to pick up multiple women, [[spoiler: including Robbie's teacher...]]
* ''Film/TheLoveOfSiam'': Ying is in love with Mew, but Mew is in love with Tong. Tong is in love with Mew, but he's also in a relationship with Donut. Donut is in love with Tong, but Tong does not love her.
* ''Film/{{Unconscious}}'': Salvador loves Alma and is married to Olivia, who eventually runs off to Paris with Frances. Alma finds both León and Salvador attractive. León has affairs with several of his patients, but claims that Salvador is the love of his life.
* ''Oscar'' (the original French movie): Colette Barnier is courted by Baron Honoré de la Boutiniere, whom she rejects, and the Baron eventually marries her maid Bernadette. Meanwhile, Colette is ready to marry just anyone who's handsome enough. She takes her chauffeur Oscar as her lover, but when he's sacked by her father, she's almost as willing to marry her father's employee Christian Martin or the masseur Phillippe Dubois. While Phillippe does fancy her, Christian is in love with Jacqueline Noiret, a typist. [[spoiler:On top of it all, Jacqueline turns out to be the illegitimate daughter of Monsieur Barnier from his affair with his former servant Charlotte]].
* Creator/IngmarBergman's ''Film/SmilesOfASummerNight'' revolves around one of these in Sweden around the turn of the century. It involves two men and two women at first, and four of each by the end.

* The main character in R. Kelly's ''Trapped in the Closet'' slowly discovers that he has stumbled into one of these. Flowchart can be found [[http://www.somethingawful.com/d/your-band-sucks/thorpes-notes-kellys-2.php here]].
* Here Comes My Baby by Cat Stevens. Especially apparent in when covered by Sons of Admirals in a [[http://www.youtube.com/watch?v=vR5wKLfzGHo music video]].
* The song "Alter Mann" (old man) by the German [[GenreBusting fun-whatever]] band Knorkator features one of these in the first verse.
-->''Daniela likes Jonas, but he has a thing for Vanessa\\
Vanessa would rather be with Lars, but he likes Melanie better\\
She on the other hand loves Tim, Tim is on love with Jennifer\\
Jennifer on the other hand likes Kevin, but Kevin is... gay\\
Tobies has the hots for Annika, and she actually likes him too,\\
but the thing is that her best friend also has a crush on him.''
* Moosebutter's song "Doug", which used to be the page quote. To explain how it works, I love you, but you love Doug. I don't really like Doug. Doug loves Martha, but Martha don't really like Doug. Martha loves Brad, but Brad don't really like Doug. Brad loves Sue, but Sue loves truth. [[CrowningMomentOfFunny Truth don't really like Doug.]]
* Music/TomLehrer: "I Got It from Agnes". Tom, Agnes, Jim, Louise, Harry, and Marie appear in the first verse ''alone''.

[[folder:Myths & Religion]]
* Despite being one of the more famous ancient cases of a MinimalistCast, the [[Literature/TheBible Garden of Eden]] turns into this once you look at all the extracanonical folklore. Adam had, by some accounts, as many as three wives, of which the only named two--Lilith and Eve--are both said by some stories to have been seduced by the Devil--[=and/or=] by ''each other'' in at least one account. Add in that the Devil has occasionally been portrayed as the ''ex-lover of God'', and in other versions has a whole harem of succubi consorts, one of whom--Namaah--may have seduced or raped Adam and subsequently given birth to Asmodeus, the Demon of Lust, who--among many other consorts and would-be consorts because, again, Demon of ''Lust''--is sometimes said to have taken Lilith as his mate and fathered a brood of demonic spawn by her. Lilith herself, meanwhile, ReallyGetsAround by almost all accounts, being simultaneously a consort of a whole slew of high-ranking demons depending on who you ask and also a succubus-like entity in her own right seducing or raping mortal men throughout the centuries--with her first mortal victim being recorded in some stories as ''Cain'', Adam and Eve's son, who also had an incestuous SiblingLoveTriangle story told about him where his sister--named Awan or Aclima depending on version - was betrothed to his brother Abel but then stolen by Cain as part of their [[CainAndAbel infamous rivalry]], while Cain's original betrothed--his ''other'' sister Jumella--ended up marrying Seth, Adam and Eve's ''third'' son. In all honesty, the tangled romances of Eden are such a mess that it's surprising we ''didn't'' end up with an [[https://en.wikipedia.org/wiki/Adam_and_Steve Adam and Steve]] at some point.

[[folder:Tabletop Games]]
* [[LevelUpAtIntimacy5 Having one of these is the surest path to survival in]] ''TabletopGame/BlissStage''.
* ''TabletopGame/{{Forsooth}}'': Comedy games tend to include this. Tragedy games are more likely to have a scheming dodecahedron.

* ''A Little Night Music'' has a series of interlocking {{Love Triangle}}s that take in most of the cast.
* OlderThanSteam: Creator/WilliamShakespeare loved {{Love Dodecahedron}}s; one found its way into most of his comedies, including ''Theatre/TwelfthNight'' and ''Theatre/AMidsummerNightsDream''.
* This also extends to all of the plays, books, and movies based ''off'' of said Shakespeare works. One such example is ''All Shook Up'': Chad loves Sandra who hates him and loves Ed who doesn't exist because he's actually Natalie because she wants to be with Chad who's first sidekick is Dennis who loves Natalie whose dad is Jim who loves Sandra and later loves Sylvia who is so jaded that she doesn't love anyone at first but later falls for Jim who gives Dennis advice on how to approach Natalie, who is friends with Lorraine who is in love with Dean who is Matilda's son who hates interracial marriage despite giving birth to a mixed child but later marries her sidekick Earl who is supposed to arrest Chad who later loves Ed/Natalie until he finds out that Ed is actually a woman and runs away. By the end of the musical, Jim is married to Sylvia, Matilda is married to Earl, Dean and Lorraine are dating, Sandra and Dennis (inexplicably) get married despite the age difference, and Chad gets over Natalie being a girl and they marry by compromising "maybe once in a while you can put on that hat and the beard... we'll work something out".
* ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'':
** Sweeney loves Lucy. So does the Judge. Mrs. Lovett loves Sweeney, who is indifferent to her. The Judge loves Johanna. Anthony loves Johanna, who loves him back. After that, things get a little confusing.
** There's also one of the "Parlor Songs":
--->''Sweet Polly Pluncket saw her life pass\\
Flew down the city road crying:\\
"I am a lass who, alas, loves a lad who, alas, has a lass loves another lad, who once I had in Canterbury.''
** "Love" is a rather strange word to use about Judge/Lucy and Judge/Johanna. "Lust" is more like it. It depends on the production, but at least in the movie adaptation she doesn't appear very loving.
* In ''Theatre/{{Wicked}}'', (at least the musical adaptation) Nessa loves Boq, Boq loves Glinda, Glinda loves Fiyero who becomes her boyfriend, and Elphaba and Glinda are best friends, but Elphaba starts to develop feelings for Fiyero. Then Fiyero starts reciprocating those feelings and ultimately breaks things of with Glinda to be with Elphaba. And to make things more complicated, being together doesn't diminish that Elphaba and Fiyero still do care about Glinda. And that's not even getting into any subtext issues. Yikes.
* The whole point of ''Aspects of Love''. Alex loves Rose who loves his uncle George who loves her back because she looks like his dead wife despite having a mistress, Giulietta. Giulietta and Rose have major LesYay while Rose and George get married and have a daughter, Jenny. Rose takes on a lover named Hugo while Jenny falls in love with Alex. Alex loves her back but is disgusted since they're [[KissingCousins cousins]]. Alex and Giulietta fall for each other while both Rose and Jenny beg Alex not to leave them...[[Film/AustinPowers and now I've gone crossed eyed]].
* ''Theatre/{{Hair}}''
-->'''Jeannie:''' This is the way it is. Sheila's hung up on Berger. I'm hung up on Claude. Claude is hung up on a cross between Sheila and Berger. And Berger's hung up everywhere. As a prospective mother I must say something very weird is going on here. And to make it worse, Woof's hung up on Berger.\\
'''Woof:''' No I'm not. I'm hung up on Mick Jagger.
* ''Theatre/ThoroughlyModernMillie''. Millie decides she'll marry her boss...once she gets one. She finally decides on Trevor Graydon. Meanwhile she had SlapSlapKiss with Jimmy and upon realizing her feelings she catches him hanging around her friend Miss Dorothy. Millie tries to go back to Trevor but he has LoveAtFirstSight with Miss Dorothy. Jimmy tries to win Millie back while one of ThoseTwoGuys hanging about falls for Miss Dorothy as well.
* In ''Theatre/TheMerchantOfVenice'', Bassanio has something going on with Antonio, marries Portia, who is loved by the Prince of Morocco and others. Then there's Jessica and Lorenzo and Nerissa and Gratiano.
* Many of Gioacchino Rossini's operas, especially ''Il viaggio a Reims'' (as it has basically no other thing for a plot). Melibea flirts with Don Alvaro though she loves Count Libenskof who gets jealous, Countess de Folleville loves the cavalier Belfiore who flirts with every girl in the neighborhood but mostly Corinna who rejects him because she loves Lord Sidney (who thinks his love is hopeless), and Corinna is also JustFriends with Don Profondo and platonically adored by all other men--got it all? Good.
* Music/WolfgangAmadeusMozart's opera ''Theatre/TheMarriageOfFigaro'' has… (deep breath) okay, here we go: Figaro and Susanna are happy together and about to be married. The Count and the Countess are already married, but aren't happy. The Countess still loves the Count, but he'd rather be off reinstating the DroitDuSeigneur with Susanna (and it's implied he's taken full advantage of this same right in the past with other women). Marcellina has a weird crush on Figaro up until she learns he's [[spoiler: her son]], and she used to have a thing going on with Bartolo, [[spoiler: which is then reignited when they find out they still have a child]]. Cherubino is a heterosexual male in the middle of puberty and so by definition wants to sleep with every female he sees, but especially Susanna, Barbarina and the Countess. Barbarina reciprocates, and the Countess reciprocates in the sequel. Bartolo still doesn't seem to have quite got over his crush on the Countess from the first play. Oh, and Barbarina also seems to have once had a thing going on with the Count, but now she only loves him "like a kitten", as opposed to her more erotic love for Cherubino. And... the Count seems to have rediscovered his feelings for his wife by the end. [[InfoDump Got all that?]]
* Rimsky-Korsakov's opera ''The Tsar's Bride''. Gryaznoy is in love with Marfa who is promised to VictoriousChildhoodFriend Lykov, while Gryaznoy has ClingyJealousGirl Lyubasha as a mistress already, and the court physician Bomelius is extremely attracted to Lyubasha [[spoiler:who concedes to his advances in exchange for him preparing a poison for Marfa]], and Tsar Ivan the Terrible, looking for a new wife, chooses Marfa as his bride.

[[folder:Video Games]]
* In ''VideoGame/BreathOfFireIV'', Ryu is in love with Nina, who is in love with Clay, who is in love with Elena, who is [[spoiler:trapped in a marriage with the evil prince.]] It was a love daisy chain, only made more disturbing by having Nina and Elena as siblings, and everyone else being different species. Significantly simpler in the orignal, as the Nina's love for Clay was added in [[{{Bowdlerise}} the translation]]. Made all the more complicated in the official manga adaptation, ''Utsurowazarumono'', where [[http://www.mangafox.com/manga/utsurowazarumono_breath_of_fire_iv/v02/c010/9.html Scias' reason]] for doing a HeelFaceTurn and returning to the party is explained by him [[http://www.mangafox.com/manga/utsurowazarumono_breath_of_fire_iv/v02/c010/15.html developing a big crush on Nina]]. (In the video game, it's just simply assumed that, due to spending so much time fighting in the party, he developed a bond with everyone.)
* In ''VideoGame/TheSims'', it's far too easy to set one of these up. It can even happen by accident. There's a pre-made one in Pleasantview in ''VideoGame/TheSims2''. Darren is love with Cassandra, who is engaged to Don, who is in love with Nina and has a crush on Nina's sister, Dina. Dina is dating Cassandra's father, Mortimer, who is married to the missing Bella, and who also has a default want to flirt with Nina. Dina was also married to Cassandra's uncle, Michael, before he died. Don also has memories of putting the moves on Cassandra's mother, Bella, just before her alien abduction. Don is also currently having an affair with Kaylynn, the maid. Kaylynn is in turn having an affair with Daniel, who is unhappily married to Mary Sue. [[http://sims.wikia.com/wiki/File:Love_web.JPG Here's a picture for those who couldn't follow that.]]
* In ''Franchise/FireEmblem'', letting the player decide how to resolve the love dodecahedron has been a major gameplay/story element since, oh, sometime before they started releasing the games outside of Japan:
** A major, plot-relevant dodecahedron encompasses ''VideoGame/FireEmblemShadowDragonAndTheBladeOfLight'', ''VideoGame/FireEmblemGaiden'', ''VideoGame/FireEmblemMysteryOfTheEmblem'', and their remakes. Nyna is in love with Camus, who reciprocates her feelings but [[MyCountryRightOrWrong puts his duty to Grust above all else]]. Hardin is in love with Nyna, who respects him as a friend but doesn't like him that way. However, Archanea needs a king after ''Shadow Dragon'' concludes, so they enter a political marriage. It ends ''badly''; after Hardin finds out Nyna never loved her, he falls into a HeroicBSOD, [[BrainwashedAndCrazy succumbs to Gharnef's brainwashing, goes completely batshit insane]], and hands Nyna over to be sacrificed to Medeus. Meanwhile, Camus survives the beatdown Marth gave him, ends up in Valentia as an amnesiac, takes the name Zeke, and falls in love with a priestess named Tatiana. He briefly returns to Archanea under the pseudonym Sirius to deal with Medeus and save Nyna, who still has feelings for him; however, he is already bound to Tatiana and returns to Valentia afterwards. In summary, Camus and Tatiana live HappilyEverAfter, Nyna DidNotGetTheGuy, and Hardin ends up {{Yandere}} and then dead.
** There's quite the LD in ''VideoGame/FireEmblemGaiden'' and its remake, ''Fire Emblem Echoes: Shadows of Valentia''. Tobin and Gray pursue Clair, who has a crush on Alm. Celica and Faye (from ''Echoes'') also have feelings for Alm, while he only has eyes for Celica. Last but not least, it's implied that Boey has a crush on Celica while, in ''Echoes'', he also has BelligerentSexualTension with Mae. In the end... [[spoiler: Alm and Celica marry; Clair either marries Gray or stays single if he dies, Faye never fully gets over Alm, Boey and Mae either marry or, if one dies, the other also stays single.]]
** ''VideoGame/FireEmblemRadiantDawn'' has a relationship Dodecahedron ''in game'', updated as the player progresses. A full version can be found [[https://serenesforest.net/radiant-dawn/miscellaneous/character-relations/ here]] (major spoilers).
* ''VideoGame/LuminousArc2'' have one ''mostly'' revolves around Roland. He can end up with either Althea or Fatima, while gaining affections, via Intermissions, from Dia (who also have a few ShipTease with his brother, Rasche), [[WingedHumanoid Sadie]] and Karen, who's oblivious to Ace's interest in her, as well as getting distracted by some of the girls in their Hot Spring Intemissions (Dia, Luna, Ayano, I'm looking at you). Rina, despite being Roland's childhood friend, just {{Fangirl}} over Richter.
* Lampshaded in the ''VideoGame/NancyDrew'' game ''Stay Tuned for Danger'', where a tabloid newspaper headline refers to ''[[ShowWithinAShow Light Of Our Love]]'' character Rory's "Love Octagon".
* One village in ''VideoGame/DragonQuestVII'' features one of these: To pay off her family's debt to the richest family in town, Linda is [[ArrangedMarriage engaged]] to their son [[UpperClassTwit Iwan]]. However, Linda ''really'' loves Pepe, one of their gardeners. Meanwhile, [[{{Meido}} Maid]] Kaya loves Iwan, but Iwan is too busy lusting after Linda and fuming with jealousy over her obvious love for Pepe. Notably, [[spoiler: things ''don't work out'' in the long run]].
* ''VideoGame/LegendOfMana'': Matilda loves Irwin (who sort of loves her back, but since he's a demon he expresses it weirdly), but is also more or less married to her job; Escad loves Matilda; Daena is torn between Matilda and Escad. It ends with [[spoiler: everybody except one person dead, Matilda as the Seventh Wisdom, and Irwin wanting to reincarnate himself without any memories of the woman he loves because it was so messy]].
* In ''VideoGame/BatenKaitosOrigins'': [[CrowningMomentOfFunny "Quadrangle"]]
* Thanks to the massive shippers and MemeticMutation ''VideoGame/{{Touhou}}'' Fanon often displays all of the characters stuck in this situation. And there's [[LoadsAndLoadsOfCharacters a lot of characters.]] Here's a fanmade [[http://danbooru.donmai.us/post/show/663898/-3-3-aki_minoriko-aki_shizuha-alice_margatroid-buu chart]] to help out. Warning: Ads are {{NSFW}}.
* ''VideoGame/AceCombat04ShatteredSkies'' has the [[{{Narrator}} Storyteller Boy]] crushing on the [[LaResistance Barkeep's Daughter]], who crushes on [[AcePilot Yellow 13]], who very much obvlivious to his [[{{Wingman}} wingwoman Yellow 4's]] feelings for him, because he is busy generating FoeYay towards [[PlayerCharacter Mobius 1]].
* In ''VideoGame/BlazeUnion'', Siskier has rather obvious feelings for her childhood friend Garlot, who is completely oblivious--partially because he's aware that their ''other'' childhood friend Jenon, despite his [[SerialRomeo incurable tendency to flirt with anything that has breasts]], has had a crush on Siskier for a long time. Siskier has no idea that Jenon likes her. Garlot himself develops a crush on Nessiah when the latter joins the party, and while Nessiah flirts with him quite a bit, it's ambiguous as to whether or not he's serious about it. So: Nessiah/Garlot/Siskier/Jenon, with crushes going from right to left; also factor in that [[UnwantedHarem most of the party is implied at some time or other to have a thing for Garlot]] and that [[ObliviousToLove this flies miles over Garlot's head]]. The resolution to this situation ([[NoRomanticResolution when there is one]]) varies by RoadCone.
* Smaller version in ''VideoGame/TheKingOfFighters''. [[TheHero Kyo]] [[PlayingWithFire Kusanagi]] and [[GirlNextDoor Yuki]] [[HighSchoolSweethearts are in a relationship]] [[OfficialCouple already]], which goes by BelligerentSexualTension in some versions. However, [[IdolSinger Athena]] [[ActionGirl Asamiya]] is all but stated to be or have been in UnrequitedLove with Kyo in the SpinOff manga and games ''The King of Fighters KYO'' (and maybe in the AlternateUniverse manga ''KOF G''), whereas Athena's partner [[BadassAdorable Sie]] [[PsychicPowers Kensou]] is her [[CrazyJealousGuy VERY clingy]] DoggedNiceGuy despite how Athena herself sees their bond as JustFriends and either ignores or rejects his love declarations. And in the KOF:KYO manga we also have [[{{Adorkable}} Takaya Maeta]] who has a massive crush on Yuki [[spoiler: and wins a date with her]], as well as Yuki's friend Sanae who encourages Maeta's crush while saying she finds Kyo hot but never directly hitting on him.
** Additionally, fanon adds other vortexes to this "dodecahedron": Kyo and [[TheRival Io]][[AntiHero ri]] have LOADS of FoeYay, [[NaiveNewcomer Shingo]] can easily be seen as having [[HoYay a huge boy-crush]] on [[EvenTheGuysWantHim Kyo]] based on [[HeroWorshipper his massive fanboy-ing]] of the man, [[YamatoNadeshiko Chi]][[BarrierMaiden zuru]] is said to have [[LovingAShadow "envisioned" Kyo as an "eternal schoolboy"]] [[spoiler: and used that to create Kusanagi when BrainwashedAndCrazy]] which [[RelationshipWritingFumble the fans have interpreted rather predictably]] and in return Kyo is ''very'' protective of [[CoolBigSis her]], the KOF:KYO manga has Athena ''seriously'' worrying for Iori's almost non-existant mental health which she ''still'' does in KOF XIII, ''and'' XIII also shows that Chizuru is among the very few people that [[JerkAss Iori]] [[PetTheDog seems to care for a little]]...
* ''Franchise/SuperMarioBros'': Mario and Luigi are both attracted to Princesses Peach and Daisy, and the feelings are mutual. Mario also at one point had a girlfriend named Pauline. Bowser is in love with Peach even though she rarely ever returns his feelings except for some ShipTease in ''VideoGame/SuperPaperMario''. There also are also at least a few other minor character who have been shown to be attracted to the Brothers or Princesses.
* ''VideoGame/FinalFantasyVII'' is well known for its LoveTriangle, but things are a little more complicated than that. Tifa likes Cloud, who had a crush on her as a child; back then she liked him just a little, but enough to make him promise he'd protect her someday. Cloud is oblivious to her current feelings, and also to those of Aerith, who is attracted to him. Aerith still mourns the loss of her FirstLove Zack, [[spoiler: who unbeknownst to her was Cloud's BigBrotherMentor]], whilst being unaware of the crush Tseng has on her. Meanwhile Rude laments the fact that Elena likes Tseng, whilst also admitting that he fancies Tifa. Yuffie has an unrequieted crush on Cloud, whilst Vincent broods over his lost love, Lucrecia, who didn't reciprocate his feelings ''despite sharing them'', and instead ran off to marry her partner aka MadScientist Hojo. There's also UnluckyChildhoodFriend Johnny, who's liked Tifa for a long time, but CanNotSpitItOut.
* The first three games in the ''VideoGame/PretentiousGame'' series are all about this trope. The blue square loves the bright pink square, but she loves the gray square, who is married to the light pink square. Then the gray and light pink squares get divorced, the bright pink and gray squares end up married with two kids, and the blue and light pink squares get into a relationship. [[spoiler: ''Then'' the gray square drunkenly kills the blue square in a car accident, which results in the blue square's relationship with the light pink square abruptly ending, the gray square going to jail, and the bright pink square presumably divorcing the gray square. Yeah, it's one of ''[[LoveHurts those]]'' stories.]]
* From ''VideoGame/CorpseParty'': Satoshi loves Naomi, who loves him back, but neither of them can spit it out. Seiko also loves Naomi, but can't confess because [[IncompatibleOrientation they're both girls]]. Yuka also loves Satoshi, but can't confess because [[{{Squick}} they're siblings]]. Yoshiki likes Ayumi, who is oblivious because she likes Satoshi, who is also oblivious. Mayu loves Morishige, who sees Mayu as a little sister, and Ms. Yui has ShipTease with Satoshi but ultimately he just reminds her of her childhood boyfriend who she hasn't seen in years. This is ''just'' the core cast, as there are a dozen other characters who make up their own dodecahedrons or add on to the main one.
* In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', Mipha is a childhood friend of Link's who harbors feelings for him, [[spoiler: even wanting to marry him]], yet it is unknown if Link felt the same. Zelda also appears to have developed a BodyguardCrush on Link and again, it's left up to the air if Link reciprocated those feelings. Kass's teacher was the court poet for the Hyrule royal family and fell for Zelda but she only had eyes on Link. There was also Kodah, another childhood friend of Link's, who also chased after him.
* ''VideoGame/DragonAgeOrigins'' lets you get matters of the heart in a very tangled skein, especially in the endgame. For example, [[spoiler: Alistair]] could be engaged in a political marriage to [[spoiler: Anora]] and end up becoming [[spoiler: Morrigan's]] baby daddy, while still being in love with the Warden, who may have had a previous relationship with two other members of the party.
* In ''VideoGame/AzureStrikerGunvolt'', Gunvolt is in the center of a LoveTriangle with surrogate sister Joule, and Quinn, the girl who gave him and Joule a new home. Gunvolt's friend Zeno is also good friends with Joule and her OlderAlterEgo Lumen, although it's quite obvious he has a crush on the latter, and Viper, a Boss in the first game, meanwhile, has a crush on Joule (Viper is explicitly called a {{Lolicon|AndShotacon}} even) instead, and is mad at Gunvolt for kidnapping her. Joule is very much a ClingyJealousGirl not just towards Quinn, but towards MissionControl Moniqa (first game) and Xiao (second game) as well, even though Moniqa has feelings for Gunvolt's mentor and parental figure Asimov, while [[MistakenForGay Xiao's a guy]]. One of the bosses of the second game, Gibril, then tells Gunvolt she fell for him after she was bested in battle, to Joule's disgust. What really complicates the relationships is TheReveal in the ending, where [[spoiler:Joule is in reality a [[PsychicPowers Septima]] [[ArtificialHuman given human form]] derived from a girl named Mytyl, who happens to be the twin sister of Gunvolt's rival and nemesis Copen.]]

[[folder:Visual Novels]]
* Most of the routes in ''VisualNovel/BrassRestoration'' focus on Ryo and his love interest, but Yoshine's route has one of these as part of the plot.
* Franchise/{{Nasuverse}}: Just look at [[http://i.imgur.com/VIcu0nD.jpg this chart]]. At least eight people in love with [[VisualNovel/{{Tsukihime}} Shiki]] plus Arihiko on the side crushing on Ciel and Akiha and possibly the maids. Even the girls at school seem to be somewhat attracted despite not being insane like his other love interests. [[VisualNovel/FateStayNight Shirou]] is ''only'' the center of four-six girls' affections (Mitsuzuri being subtext and Ilya being up to your interpretation, but probably only familial), but there's other entanglements besides his making it even ''more'' complicated when you figure in [[StalkerWithACrush Gilgamesh → Saber]] and [[BodyguardCrush Bazett → Lancer]] and Avenger. Curse you Nasuverse!
* The first ''VisualNovel/FragmentsNote'' has this. [[ShamelessFanserviceGirl Mischa]], [[NotBloodSiblings Haya]], and [[ChildhoodFriendRomance Yukitsuki]] love Yukiha, who might love them all back, or he might love [[DoesNotLikeMen Eri]], who eventually might develop feelings for him. Keep in mind that Eri is abnormally cordial towards [[TheSmartGuy Mikiya]] despite hating most guys, and Mikiya "holds Haya in high regard" and might love Mischa, while [[ButtMonkey Kazuhide]] blatantly loves Mischa and Haya.

[[folder:Web Animation]]
* Volume 2 of ''WebAnimation/{{RWBY}}'' establishes one, although it's only a subplot at best. Pyrrha likes Jaune, who likes Weiss, who likes Neptune, who likes pretty much any girl who will give him the time of day (and a few who don't).
* ''Webanimation/TerribleWritingAdvice'' parodies this in [[https://www.youtube.com/watch?v=9F-Ycl70vsQ one video on Urban Fantasy,]] showing the obvious choices such as [[Literature/{{Twilight}} vampire and werewolf,]] as well as many others, including [[{{CelestialParagonsAndArchangels}} an archangel,]] [[{{HornyDevils}} an incubus,]] and an [[{{EldritchAbomination}} Eldritch Abomination.]]

* [[TruthInTelevision These aren't as uncommon as one might think]]. This sort of thing can happen in any [[http://www.myconfinedspace.com/wp-content/uploads/tdomf/73014/Adolescent%20romantic%20network_reviseda.jpg social circle or group of friends.]] ''Especially'' with teenagers.
* In Carrie Fisher's memoir, ''Wishful Drinking'', she has a chart indicating all of her parents' marriages, and her siblings, step-siblings, etc.
* The Pre-Raphaelite Brotherhood was eaten up with this trope. Dante Gabriel Rossetti married his model Elizabeth Siddal, but also had an affair with another model, Jane Burden, who married another artist, William Morris. Rossetti also had an affair with Annie Miller, a barmaid and the fiancee of artist William Holman Hunt. Hunt took her back, but finally broke off the engagement when Annie became involved with the 7th Viscount Ranelagh. Annie Miller ended up married to Ranlagh's cousin while Hunt married Fanny Waugh, and after her death, remarried to Fanny's sister Edith. His colleague, the sculptor and poet Thomas Woolner, had also been in love with Fanny Waugh; he married Alice Waugh, the third sister of Fanny and Edith. Meanwhile, John Everett Millais fell in love with Effie Gray, who was still a virgin despite being married to critic John Ruskin. They wed after she left Ruskin.
* Simone de Beauvoir and Jean Paul Sartre, who had been in a lifelong relationship, are known to have been involved in one as de Beauvoir made it the basis for her novel ''She came to stay''. It involved one of de Beauvoir's teenage students in whom Sartre had been interested, but being ignored he turned to her sister, who eventually ended up marrying one of de Beauvoir's former lovers. It's unknown what part he played in it, but the whole thing was the reason that ended Sartre's friendship with Creator/AlbertCamus.
* Two days after UsefulNotes/BarackObama was reelected, CIA Director and FourStarBadass David Petraeus became the focus of one of these, which is still-expanding. It cost him his job, may put his biographer in jail (for removing classified materials), could sink or derail a number of military careers, deal a blow to American intelligence efforts and effectiveness around the world at a crucial time, [[ArsonMurderAndJaywalking and provided plenty of fodder for late-night comedians who thought that they had lost a mother lode at Mitt Romney's election loss.]]
* Music/FleetwoodMac: The Music/{{Rumours}} album and tour. Before the start of the album, there was a married couple (the [=McVies=]), a committed unmarried couple (Buckingham and Nicks), and Fleetwood had a wife outside the band. As the album and tour was being made, Fleetwood divorced, the [=McVies=] divorce followed, Buckingham and Nicks were breaking up (the song "Go Your Own Way" is pretty much them playing their nasty breakup for Top 40 radio), Nicks started an affair with Fleetwood...add groupies, alcohol, and a small mountain of cocaine to make matters even worse, and ''all of them'' were stuck together on tour.
