[[StunnedSilence ......]]

Sounds about right!

While critically acclaimed, the film had disappointing sales and box office numbers, possibly due to how [[LighterAndSofter completely different it is from the director's other works]].
!!I'm a Troper, But That's OK:
* ApologizesALot: One of the patients apologizes for damn near '''everything'''.
* ArmCannon: Young-goon imagines that as a cyborg she can turn her hands into machine guns.
* ArmorPiercingSlap: When Young-goon rails on Il-soon for stealing her dentures.
* BerserkButton: Don't talk about mothers in front of Il-soon.
* BetaCouple: Kyu-suk and Eun-young.
* BungledSuicide: The very opening scene (although it wasn't actually intentional).
* CastOfSnowflakes: If there is any example of this trope, [[UpToEleven it's this]].
* CharacterTics: Considering their mental health, it's understandable several of the characters have them (although they're mostly played for humour).
** Young-goon talks to electric objects wearing dentures and attempts to shake hands with people (who she actually wants to shoot).
** Il-soon wears masks based on other people's faces, hops around like a rabbit, and furiously brushes his teeth when upset.
** One male patient walks backwards, says redundant and meaningless things, and considers everything to be his fault.
** Eun-young dresses like Literature/{{Heidi}}, never looks away from her mirror, and practices singing.
* {{Cloudcuckoolander}}: '''''All''''' of the patients.
* CompanionCube: Young-goon has her granny's dentures. She also has a radio, bedside lamp, and the vending machine which she regularly talks to.
* ConsummateLiar: Sul-mi, one of the patients in the institution, is a mythomaniac.
* CueTheSun: The final shot is of a beautiful sunrise [[spoiler:revealing that Young-goon and Il-soon survived the storm]].
* DidTheyOrDidntThey: It's implied, but never confirmed, that [[spoiler:Young-goon and Il-soon have sex]]. Considering they're both {{cloudcuckoolander}}s, anything could've happened.
* ElectricTorture: The shock therapy is portrayed as this. Sul-mi actually loses her memories every time she has it.
* EmotionlessGirl: Young-goon tries to be one, since cyborgs shouldn't have emotions.
* FatGirl: Gop-dan, who is the only overweight character around, and one of the most selfish, unsympathetic, and overall [[{{Pride}} vainest]].
* ForceFeeding: Young-goon is subject to this since she won't eat, with realistically horrible results.
* GadgeteerGenius: Mentally unstable or not, Il-soon shows off his creativity and inventing skills, the Rice Megatron being the sum of all this. It's explained that he used to work as a technician.
* GoryDiscretionShot: When Young-goon slits her wrist.
* ImNotHungry: Young-goon refuses to eat, if only because she thinks she's a cyborg, and cyborgs don't ''need'' food.
* InelegantBlubbering: Everyone.
* LackOfEmpathy: Young-goon wants to get rid of her sympathy so she won't feel bad about [[spoiler:murdering the doctors]].
* LighterAndSofter: Compared to Park Chan Wook's other works.
* LivingEmotionalCrutch: Il-soon eventually becomes this for Young-goon.
* ManInWhite[=/=]WomanInWhite: Il-soon and Young-goon primarily, but virtually everyone wears white.
* MeaningfulEcho:
** "Just give up hope, and stay strong."
** "Why would a girl like you want to die? We must carry on living through thick and thin."
* MeetCute: As cute as you're gonna get at a mental hospital.
* MissingMom: Il-soon's mother not only abandoned them when he was 15, she also [[FelonyMisdemeanor took the whole family set of electric toothbrushes]].
* MyCard: Il-soon gives Young-goon a very convincing one he made himself, with a lifetime warranty.
* NoPeriodsPeriod: Averted. Young-goon tells her mother she's a cyborg, and her mother asks her if she's feeling strange because she missed a period.
* NoSenseOfPersonalSpace: Most of the patients display this.
* OneHeadTaller: Il-soon and Young-goon. This is played with during [[spoiler:their first kiss]], where they both try and solve the height difference.
* OnlySaneMan: The doctors, quite literally.
* ParentalNeglect: Young-goon's mother is too busy/ashamed to seek help for her, and Il-soon's parents ignored him so much he genuinely thought he was invisible.
* RaisedByGrandparents: Young-goon's mother tells the doctor that her mother mostly raised Young-goon at the beginning of the movie, explaining why Young-goon is devoted to her granny.
* ReadingLips: Il-soon is shown to be quite good at this when interpreting a distraught Young-goon. It is shown that he learned it from one of the doctors who apparently reads the lips of crying patients. [[ChekhovsSkill It comes in handy later]].
* RoaringRampageOfRevenge: [[spoiler:Young-goon]] goes on an imaginary one against the "white-coats" for incarcerating her. It may not be real but it's [[ThereIsNoKillLikeOverkill pretty disturbing]] while it lasts.
* RuleOfFunny: See WillingSuspensionOfDisbelief below.
* ShirtlessScene: It's ''Rain!'' Would be a complete waste not to let him take his shirt off at least once.
* SoundtrackDissonance: A light hearted waltz plays during Young-goon's [[spoiler:bloody killing spree]].
* StepfordSmiler: Doctor Seul-ki may be this. It's understandable that working in a mental hospital would take its toll on her.
* SurrealHumor
* TakeOffYourClothes: When Il-soon [[spoiler:pretends to install the Rice Megatron]] in Young-goon's back, he asks her to do this. Subverted as he's the only one who realises how awkward the request sounds.
* TinCanTelephone: Il-soon uses one to communicate with Young-goon while in solitary confinement. He then sings her a song about YodelLand.
* ToplessnessFromTheBack: Played with. When Young-goon takes her top off in front of Il-soon you'd certainly expect fanservice, however instead we get to see how emaciated she's become. Il-soon is clearly distressed by this, although he still caresses her bare back for good measure.
* TroubledFetalPosition
* UnusualEuphemism:
-->'''Young-goon:''' Anyway, let's just take off our wet socks.
-->'''Il-soon:''' More than our socks are wet...
* UnusualEyebrows: Young-goon's eyebrows are white for some reason.
* WhatIsThisThingYouCallLove: Young-goon is a cyborg, so she convinces herself she can't feel love and has difficulty returning Il-soon's feelings, although it's obvious she reciprocates.
* WhyAmITicking: Granny tells Young-goon that she is not a cyborg but [[spoiler:a nuke bomb, and her purpose it to blow up the world]]. Young-goon tries to go through with it.
* WillingSuspensionOfDisbelief: The director has openly admitted that the mental institution as depicted in the film is deliberately the antithesis of what a real one is like. This was done for narrative purposes.
