Alice loves Bob, and Bob loves Alice. But then, it would be [[DepartmentOfRedundancyDepartment too easy if it was this easy]]: [[TheoryOfNarrativeCausality for some reason]], Alice and Bob [[{{Tragedy}} cannot be left to live happy together]]. Sometimes, this leads to LoveMakesYouCrazy, when Bob stops acting rationally to stay with Alice. Sometimes, Bob decides to [[MurderTheHypotenuse take care of this annoying guy who claims he wants to just be Alice's friend]]. Sometimes, [[LoveMakesYouEvil Alice decides to torture and murder all of Bob's female friends]] so he won't be distracted by all these, well... Sometimes, Bob coldly decides to sacrifice his TrueCompanions to [[AlwaysSaveTheGirl save Alice]].

This is none of these situations. This is when Alice and Bob stay, most of the time, level headed and genuinely try their best to be together, and notwithstanding their success or failure, the CollateralDamage is at least 147 deaths, the destruction of three cities, and maybe even the EndOfTheWorldAsWeKnowIt. Even if it can involve some irrationality (after all, LoveMakesYouCrazy or sometimes evil), it's not the characters' flaws, but the circumstances that force the couple to go to extreme length to be together. Or, even worse, they didn't even realize what they were doing, and the couple's stubborn insistence on being together results in [[NiceJobBreakingItHero an unintended ripple effect of death and destruction]]. In short, this trope is not about characterization, it is about the effects of a relationship on the story and the setting.

Can involve LoveMakesYouEvil or LoveMakesYouCrazy. This is an inversion of DestructoNookie where the rampage part involves only the couple, and usually does not leave the bedroom.

This is a trope about how romance can be really, really destructive. That's just what happens when you place the huge power of love into the hands of someone in love. They become irrational, and mad with power. Expect at least one case of MurderTheHypotenuse, especially if there is a {{Yandere}} involved.

The TropeNamer is ''LoveActually'', by way of its {{tagline}}, though it's not an example.

Related to LoveMakesYouEvil and LoveMakesYouCrazy. Also related to DestructoNookie. Sometimes caused by AlwaysSaveTheGirl.

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Manga/MiraiNikki'': By the end of the series, [[spoiler:we learn that [[{{Yandere}} Yuno]] and [[KidWithTheLeash Yukiteru]] were once this in another world. When Yuno won the right to succeed [[MeaningfulName Deus Ex Machina]] in the first world, her first act as the new God was to attempt to resurrect Yukiteru. Needless to say, it did not go well. Everything we know of her in the series is the Yuno who has already long since crossed the MoralEventHorizon by abandoning the first world and creating a second where she could replay her day with Yukiteru. It is heavily implied though that they fit this trope very well in the first world, before the events of the series and the original Yukiteru's death.]]
* ''Anime/RebuildOfEvangelion'': Shinji triggers TheEndOfTheWorldAsWeKnowIt just to save Rei.
* in ''Manga/TsubasaReservoirChronicle'', [[spoiler: Shaoran causes the time to rewind and a lot of characters suffer because of this, in order to save Sakura.]]
** Also, in ''Manga/{{X1999}}'', Kamui's wish to get [[spoiler: Fuuma]] back even if it causes [[spoiler:Fuuma]] and the rest of the world harm. Can also be said for a lot of other characters.
* ''VisualNovel/UminekoWhenTheyCry'': Kinzo and Beatrice ([[spoiler:and Beatrice and Battler]])

[[folder:Theatre]]

* Love rarely ends happily in the operas of Creator/RichardWagner. (Of course, [[WesternAnimation/WhatsOperaDoc what did you expect in an opera -- a happy ending?]]) It causes Senta to jump off a cliff, [[Theatre/{{Tannhaeuser}} Elisabeth and Heinrich]] apparently just to keel over, Elsa to betray Lohengrin and ''then'' to keel over, [[Theatre/DerRingDesNibelungen Siegmund to commit adultery with his own sister and be killed by her husband (she dies in childbirth), Gutrune to drug Siegfried into loving her so that ''his'' wife kills him and then burns herself to death]], and Tristan to get fatally wounded while messing around with Isolde, the king's wife, who then herself keels over. Only Walther and Eva seem to end up well.
* Romeo's and Juliet's neighbors got off easy compared to the citizens of Rome and Egypt in Shakespeare's ''Theatre/AntonyAndCleopatra'' when their affair starts a war and turns all their people against them.

[[CannotSpitItOut Without even knowing how the other feels.]]
