It's time for the second TV Tropes Halloween Avatar Contest, theme: cute monsters! Details and voting here.
Alice has some long-standing grudge with Bob, or they have just had a very acrimonious breakup. Alice then strikes up an intimate relationship with Charlie, a close friend or relative of Bob's, not because she has sincere feelings for Charlie, but to get back at Bob.
This becomes Operation Jealousy
if Alice is trying to manipulate Bob back towards loving her.
- Happened at least twice in Detective Conan:
- One was the case of a young man who, on his wedding-day, poisons his bride - the daughter of the local Chief of Police - in revenge for said Chief causing the death of the young man's mother through carelessness years before. Indeed, he had started a relationship with her and proposed marriage, just to get his revenge on the man who left him an orphan. What he doesn't know is that the daughter is his childhood sweetheart.
- In another case, the (highly unpleasant) patriarch of a wealthy Zaibatsu family is murdered on a cruise-ship, on his way home from his granddaughter's wedding. It soon turns out that the groom is secretly the son of a man who committed suicide after said patriarch ruined his business. The man even admits that he initially started the relationship in order to get closer to the man, so he could find a way to get revenge - but adamantly insists that he eventually came to genuinely love her, and that he has nothing to do with the murder. What's more, they decide to renounce the family estate and lived Happily Ever After.
- This is an important, not to say central, plot element of the Tsukigomori drama and its remake 'Cloudy Moon,' which the main characters spent a lot of Skip Beat! filming. Ren's character, the lead, is engaged to Kyouko's character's older sister (even though he actually likes the abused foster-sister) as part of a long-term plan to avenge himself on the family. Because fiancee-Meiyou's father was responsible for murdering Katsuki's whole family when he was a kid and disguising it as one of those car-over-a-cliff suicides. He has to keep her believing he loves her madly, or his whole scheme will collapse.
- This scenario is modeled closely on a fusion of two real famous classic Japanese dramas. The second Conan example is a subversion homage.
- It also mirrors Ren's situation with Kyoko to an amusing degree—not the fake romance, but the need to maintain the reinvented identity and therefore to stay apart from the girl he likes. Hell, she's even similar, with the Cinderella angle.
- The appropriately-named Revenge has Emily, the main character, dating, and then getting engaged to Daniel, the son of her sworn enemies Conrad and Victoria Grayson as a part of her vengeance plan.
- Friends has Chandler's elementary classmate (played by Julia Roberts) seducing him, stealing his clothes and abandoning him in a restaurant bathroom as revenge for pulling up her skirt. This happened when they were about nine and he was going through his parent's divorce at the time so the revenge is definitely an overreaction and Played for Laughs.
- In one episode of Fairly OddParents, Timmy wishes he no longer had emotions, and his resulting stoicism makes him extremely popular, to the point where Trixie appoints him as her boyfriend. When Timmy remarks that this doesn't make him feel anything, a spurned Trixie starts dating Chester instead to spite him. Naturally, this doesn't work, and Chester doesn't like it either because girls make him break out in hives.
