I didn't want you around
Those pretty faces always made you
Stand out in the crowd
But someone picked you from the bunch
One glance was all it took
Now it's much too late for me
To take a second look"
Before the crisis, the character is perfectly fine being Just Friends or totally platonic bickering partners with another. But then, that other character gets romantically involved with an interloper, causing their not-at-all love interest to suddenly feel the sting of their absence. Once they finally admit to themselves their feelings, the Romantic False Lead's got hell to pay.
In some works, this is the cue for a Relationship Upgrade. In other works where Status Quo Is God, the envious one will stubbornly refuse to come clean and revert back to her "friend" self once the romantic complication is out of the picture. It's a Aw Look She Really Does Love Him moment — but a hidden one. This arc is especially common when the jealous one is a Tsundere.
Sometimes this trope comes into play after a couple has broken up, with one side having convinced herself that she's over him until seeing her ex with a vixen causes her to gnash her teeth.
If one partner isn't in denial and deliberately stages such an incident to make the other jealous and admit her feelings, he's pulling an Operation: Jealousy. Sometimes overlaps with Unrequited Love Switcheroo — a flip between which lover's love is unrequited. The writer might need to Derail the Love Interest if the new love is working out too well for the plot to continue.
- Rumiko Takahashi is the Queen of this trope:
- Ranma ½: Multiple times, both ways, between Ranma and Akane, Ranma and Ukyo, and Ranma and Shampoo. Seen mainly in the Ranma-Akane interaction, since they only show how much they care for each other when one of them is endangered, and they always have an excuse to cover up their very apparent jealousy.
- Inuyasha: Happens in both directions between Inu-Yasha and Kagome, with Koga as Kagome's Romantic False Lead and Kikyo as Inuyasha's Psycho Ex-Girlfriend back from the dead, and includes the added mind-screw element that Kagome and Kikyo are technically the same person.
- In Accel World, Kuroyukihime meets Haruyuki's Childhood Friend Chiyuri on bad terms, and at the time, Kuroyukihime claims that it's because she thinks Chiyuri is Cyan Pile, a Burst Linker who's trying to eliminate her for a point bounty.

- Implied in Fairy Tail. During the Grand Magic Games arc, Lyon, Gray's rival and fellow disciple of Ur, makes advances on Juvia, who's madly in love with Gray, even if he doesn't notice. Around this time, Gray gradually starts to notice Juvia's feelings for him.
- I Can't Understand What My Husband Is Saying has a variation in the backstory. When Hajime and Kaoru had been working at the same company for a while, Hajime asked out a co-worker and got turned down, and he took it pretty hard. Seeing him that upset made Kaoru upset, and she realized she was jealous of Hajime's strong feelings toward the co-worker even though they didn't get together. This forced Kaoru to admit her feelings for him, leading to the unlikely relationship that forms the basis of the series.
- In Itazura Na Kiss Naoki Irie finally comes to terms with his true feelings for Kotoko Aihara after he hears that her longtime friend Kinnosuke proposed to her. He confronts her and tells her that he doesn't want her loving anyone else. The pair share their first honest kiss and get their Relationship Upgrade. It only gets better from there.
- Fujiwara invokes this on Kashiwagi in chapter 16 of Kaguya-sama: Love Is War. She asks for Kashiwagi to image her boyfriend with another girl and if she feels bad or annoyed then that means she loves him. The hilarious part is that Kaguya also imagined Shirogane with Fujiwara and was furious. She didn't take the implication that it meant she cared for Shirogane well.

- In the canon movie The Last: Naruto the Movie, Naruto realizes he's in love with Hinata because he noticed that Toneri took an obsessive interest in her.

- Love Hina appears to run on this and equal doses of Not What It Looks Like and Comedic Sociopathy resulting in Keitaro's Made of Iron status. Both Naru and Keitaro love calling out each other's faults, and it's rare when Keitaro doesn't get the shit beat out of him for something he can't help or wasn't his fault in the first place, but as soon as someone else starts showing some kind of affection towards Keitaro, count on Naru to start some shit to break up the cozy atmosphere.
- In the Lovely Complex manga and anime, Otani has never been able to see Risa as anything other than a friend...until she's suddenly swooning over Maity-sensei.

Riza: ...Why should you be annoyed?
Otani: How should I know? Annoying things will, of course, annoy me!! Don't ever mention his name again!!
- In Nana, Shoji was this; even though he was cheating on her with his co-worker and classmate Sachiko and broke up with Hachi to be with her, he gets jealous when he hears that Hachi has found a new boyfriend who was pleasing her in ways that he didn't because he didn't think them important. Although he denied his feelings to friends again when he heard that Hachi was engaged, he finally admits to Sachiko that he regrets hurting her and that he became "far-sighted" when he finally got Hachi as his girlfriend.

Inverted in a later arc, when Nico realizes that she doesn't really love her then-boyfriend Victor after finding that Lillie's attempts to flirt with Victor just annoy her rather than really angering her.
- Elizabeth of For Better or for Worse had this problem: one plot arc involved her breaking up by proxy with Anthony before the school dance, only to get insanely jealous when her friend felt sorry for him and opted to take him instead. Infamously, this plotline was later echoed and writ large when Anthony got married and Liz lamented that she should have been the one he chose instead. Interestingly, Anthony's wife is openly distrustful toward Liz, which adds more strain to the marriage, which ultimately falls apart, and Liz and Anthony get together in the end.

- A Crown of Stars: During a conversation, Asuka tells Shinji she got hurt when she caught Rei and him talking because she realized how strong her feelings towards him were and at the same time she thought she had already lost.
- Doing It Right This Time: Subverted. When Asuka begins to suspect that Rei's feelings towards Shinji are not sisterly at all she gets jealous... and then stops herself, remembering that was when everything started to go wrong in the original timeline (she loving Shinji but being unable to spit it out and being jealous of Rei because she thought that Shinji liked her was a major factor in her break-down).

- Jasmine in Deltora Quest is lured into a trap by the Shadow Lord, where he baits her into coming into his lair (and thus prompting Leif to follow and rescue her) with a fake long lost sister. Part of the reason she is vulnerable to the ruse is that Leif had been hanging around a Toran lady who she suspected was his betrothed, and this bothered her for some reason. Her fears were unfounded as the Toran lady was actually Leif's temporary heir; a distantly related cousin whose identity he had to keep secret in case she was targeted. Perhaps a little communication might have helped, but then again if the misunderstanding hadn't revealed the green-eyed monster, they might have never gotten around to spitting it out.

- Parks and Recreation
- In "Galentine's Day", Ann becomes jealous at how April has gotten the attention of her ex-boyfriend Andy, although it's not so much that Ann still harbors romantic feelings for him as much as it stems more from You Never Did That for Me due to how Andy's become much more considerate of others ever since she broke up with him and she's slowly starting to realize her relationship with Mark isn't really satisfying her.

Unusually for arcs invoking the trope, she doesn't get him in the end. Here the rival is the song's point-of-view character, possibly the artist herself — more normally we follow the fate of the girl having the epiphany.
- Toby Keith's "How Do You Like Me Now?" is about a guitarist/songwriter gloating through the radio at the girl who rejected him in high school and went on to marry some rich guy who never has time for his family. The video, on the other hand, makes it clear that his ex-crush still isn't very impressed with him.

- Tchaikovsky's Eugene Onegin has a tragic example: Eugene hadn't returned Tatyana's affections until after she married Prince Gremin, after which he realized that he had loved her all along.

- In Dog In A Manger by Lope de Vega, the secretary Theodoro has a love affair with one of Countess Diana's (his employer) maids. She discovers this, which forces her to reflect on her own feelings for him and kicks off the entire plot. Lampshaded when Diana makes him read and review a love letter she wrote " for a friend who asked for some advice", where she outright states that she "loves because she is jealous" (in that precise order). Theodoro then writes an answer to that letter in which he hints that he loves her too, and which pushes her to (sort of) confess her love, thus further encouraging him.
- Super Robot Wars games play with this trope and Kouji Kabuto. Kouji in Mazinger Z has Love Interest in the form of Sayaka. Kouji also appears in UFO Robo Grendizer, where he has another Love Interest, Maria Grace. Both of them are Tsunderes. It's a Running Gag that whenever they meet in Super Robot Wars game, they both get hit by a Green-Eyed Epiphany and start fighting over him. The best part? Kouji has no idea what's going on.
- Valkyria Chronicles plays with this trope when dealing with Welkin and Alicia. Welkin's mannerisms and (for the lack of a better word) obsession with nature put Alicia off in the early going, but as the game progresses, she begins to appreciate how Welkin's knowledge gets them out of rough situations. The anime, however, jacks it Up to Eleven.
- A non-romantic variant of this happens in Persona 4. Rise, an Idol Singer who's on hiatus, is forced to realize how much she actually used to love being an idol in part because of her jealousy over the rising popularity of her rival Kanami, who's seen as Rise's replacement.
- El Goonish Shive: Elliot and Sarah are childhood friends. Sarah isn't in denial about her feelings, but Elliot pretends he doesn't notice, and he's dating Nanase. When Sarah finds this out, she runs off crying. Who steps up to the plate and fixes things? Nanase, of course, by dumping Elliot so she can move on and he can be with Sarah. It helps that Nanase later realizes she's a lesbian and this is why she never felt sexually attracted to Elliot.
- Margaret from College Roomies from Hell!!! only starts to return Dave's affections when he finally starts to return Blue's.
- Skin Horse: Marcie has started 'dating' Chick Magnet/Wholesome Crossdresser Tip. Slightly less effeminate Chris (who is begrudgingly forced to admit that he understands why Marcie is attracted to Tip a little too well) won in the end when his jealousy forced him to make a move for Marcie... which may have been Tip's intention all along. For the record, Tip's reaction to being dumped was essentially "K. Can we still have sex?"
- Bittersweet Candy Bowl: LUCY. Oh dear god, Lucy. After nearly a decade of Belligerent Sexual Tension with Nice Guy Mike, she finally realizes she's in love with him - almost a year after he gets back together with Sandy!

- Ron's jealousy towards Kim's relationship with Eric is what ultimately made him realize that he has feelings for Kim.
- The convenient Mankey/Monkey concerns Ron had about Kim's earlier boyfriend, Josh... although Ron helped her somewhat with that romantic pursuit despite his misgivings.
- The same happened to Kim herself when she jelled against Ron and Yori. And Ron's growing friendship with Felix as well, which was especially amusing since Kim apparently has a "Ron Night" each week, of which both she and her parents are aware, and yet she didn't consider that maybe they had a little more going on than simple friendship.
- Subverted in the "Burning Low" episode of Adventure Time when it is made to appear that Princess Bubblegum is jealous of Finn dating the Flame Princess, even including an overwrought "I thought I was ready for this!" after she found out. In the end, she's actually conflicted because she knows that extreme romantic feelings would stoke Flame Princess's flames to the point of destroying the planet, and she's aware that she'd consequently have to hurt Finn by forcing him to stop dating Flame Princess.

Because of that, Lois can finally understand how Peter can get so jealous, and the couple resolves to live with their mutual jealous natures.
- In Star vs. the Forces of Evil, Star Butterfly constantly encouraged her friend Marco Diaz to ask out his crush, Jackie-Lynn Thomas. In "Bon Bon The Birthday Clown", when Marco and Jackie finally go out, Star becomes insanely jealous.
