[[caption-width-right:256:Otani & Koizumi in the anime.]]

At 172 cm (about 5'7"), high school student Risa Koizumi is way taller than most other girls. This makes her very self-conscious, which she tries to cover up by acting strong-willed and sarcastic, rarely showing her more sensitive side in public. That her name means "Little Spring" doesn't help much either.

Then she meets Atsushi Otani ("Big Valley"), captain of the basketball club, although he is short for a guy at 156 cm (5'1"). Otani's personality is a bit rough around the edges, so he and Koizumi don't hit it off well at first. Most of the time they try to one-up each other with snide remarks, giving them the reputation of being the high school's "All Hanshin-Kyojin" (referring to a comedy duo with one tall and one short member).

Despite all this they become good friends, since they share the same musical obsessions and zany sense of humor and promise to help each other out with their crushes. It is only a matter of time then before Koizumi discovers she might feel more for Otani than just friendship. But does he feel the same for her too, since she is way taller than he is?

Started as a [[{{Shojo}} shojo]] manga by Aya Nakahara, and adapted as an anime and live-action movie. The anime preserves much of the snark and energy of the original. The rollercoaster-ride of Koizumi's and Otani's relationship gains a lot of depth by way of a cast of lovable characters, which makes the series a pleasurable watch till the very end.

Creator/DiscotekMedia has announced a sub-only release of the anime series in North America.

!!Tropes:
* AccidentalKiss: [[spoiler:Otani passes out from his fever and falls on Risa's lips while trying to get a piece of rice out of her hair.]]
* ACupAngst: After meeting Hitomi, a rather buxom woman who flirts with Atsushi, Risa comments that she has no breasts with a rather dejected look on her face.
* AllGirlsWantBadBoys: Otani surely isn't Mr. Sweet most of the time
** To be fair, Koizumi is hardly Miss Sunshine either...
* AlmostKiss: [[spoiler:Koizumi and Kohori]]
** [[spoiler: Happens twice in the manga with Risa and Otani. The first time, they're interrupted by Mimi in Otani's room and the second time they are interrupted by Nobu and Nakao while the two are on the bridge after Otani found out he passed his exam.]]
* {{Angrish}}: Koizumi slips into this occasionally.
* [[AttentionDeficitOohShiny Attention Deficit... Ooh, Shiny!]]: Otani and Koizumi can instantly drop angst, romance, or anything they were doing at the moment they see swimming pools, rickshaws, or Umibouzu.
* AwLookTheyReallyDoLoveEachOther: Otani/Koizumi
* BaldOfAwesome: Umibozu.
* {{Beauty Brains And Brawn}}:
** Ishihara Nobuko: Beauty; {{Team Mom}}, TheFashionista
** Tanaka Chiharu: Brains; {{Brainy Brunette}}, {{The Smart Girl}}
** Koizumi Risa: Brawn; {{Fiery Redhead}}, {{Tsundere}}
* BetaCouple: The matchmaker friends.
* BewareTheNiceOnes: Suzuki fails to get into the same college as (sweet, meek, quiet) Chiharu, and seriously considers breaking up with her because he feels insufficient as a boyfriend. When she finds out, ''she picks up a desk and throws it, just barely missing him''. She remains angry enough for a while to involuntarily tear magazines in half whenever she remembers it, too.
* BigLittleBrother: Risa's younger brother is significantly taller than her.
* {{Bishonen}}: Suzuki, Otani, Haruka, Kohori, but especially Maitake and Seiko.
* BishieSparkle: Maitake's "magic".
* BitchInSheepsClothing: Mimi. She gets better.
* BlondeBrunetteRedhead: Nobu (blonde), Chiharu (brunette), and Risa (redhead).
** Suzuki (blond), Nakao (brown hair), and Otani (redhead).
* BokeAndTsukkomiRoutine: Otani/Koizumi obviously employ this trope, but it also comes up in casual conversation almost constantly, with Koizumi usually acting as the Tsukkomi. See also KansaiRegionalAccent, below.
* BookDumb: Both Koizumi and Otani
* [[BreakHisHeartToSaveHim Break Her Heart to Save Her]]: A variation; Nakao doesn't want Nobu to feel guilty about [[spoiler:leaving him to go take care of her grandma in Hokkaido while attending university up there]], so he tries to get her to hate him. The plan he comes up with is completely ridiculous and hilarious. It also doesn't work, though that's obviously for the better.
* ButtMonkey: Poor Kohori
* CaughtOnTheJumbotron: Two characters get caught having a heart-to-heart discussion about their relationship.
* ClassTrip: with a very central role to the plot
* ClingyJealousGirl: Mimi towards Otani at first, though she gets better. Otani and Risa towards ''eachother'', and Haruka towards Risa, though he later gets better too.
* CompletelyMissingThePoint: Happens ''far'' too often with Otani. (See ObliviousToLove)
* CompressedAdaptation: The anime series compressed all of the manga up until after Otani's entrance exam into 24 episodes, leaving out or changing some events that happened in the manga, fortunately not affecting the story too much.
* CornerOfWoe: Haruka is a frequent occupant.
* CreatorCameo: The stylist who works with Mimi and helps Risa dress up in the final episode is called Nakahara-san. ''Lovely Complex'''s mangaka is Aya Nakahara.
* TheDandy: Haruka
* DawsonCasting: In the live-action movie, all the main cast ''except'' the actress playing Koizumi is clearly much older than their supposed age. Averted with her, as she just as clearly is playing almost her own age.
* [[DoggedNiceGuy Dogged Nice Girl]]: Koizumi
* DynamicEntry: Nobu-chan frequently does this to Koizumi, usually involving a knee to the ''kidneys''. Ouch.
* EarnYourHappyEnding: Koizumi has to do this over, AND over, AND over, AND over again until things go right.
* EffortlessAmazonianLift: Carrying a guy who struggles to escape to a changing room? Not a problem for Koizumi.
* FaceOfAThug: Umibouzu. His wife even says that, despite his angry appearance, he's actually a very kind person.
* FallingInLoveMontage: Koizumi imagines this would've happened, had she and Otani been of 'normal' height.
* {{Forceful Kiss}} : Koizumi does this to Otani.
** And Otani does this to Koizumi when confessing to her.
* FunTShirt: In the prequel/WhereAreTheyNow collection of stories called ''Lovely Complex Plus'', Yoshi is seen wearing a shirt with a [[http://anymanga.com/lovely-complex-plus/001/002/006/ very interesting phrase]] on it. (NSFW) Needless to say, it was removed by Viz for English-speaking readers.
* [[GaussianGirl Gaussian Man]]: [[HotTeacher Maity]], when introduced in the anime.
* GetAholdOfYourselfMan: Koizumi's famous [[MegatonPunch "Ahou Punch"]].
* GenkiGirl: Seiko
* {{Gonk}}: Risa is normally pretty good-looking, but she can make some rather...strange faces if she's in a bad mood or is trying to be more [[YamatoNadeshiko "traditionally" cute.]]
* GratuitousEnglish: [[spoiler: Otani: "I'm breaking up with Koizumi...''FOLEVER!'' "]]
* GreenEyedEpiphany:
** Koizumi's not actually going out with someone else but [[spoiler: Maity-sensei takes it upon himself to make Otani jealous, getting him to ''finally'' realize he likes Risa. It's the OperationJealousy variation.]]
** Similarly, after [[spoiler: Seiko starts flirting with Otani, Risa starts getting jealous as well, which leads her to start admitting she likes Otani.]]
* HeadbuttOfLove: Koizumi and Otani do this after Otani [[spoiler: passes his entrance exam.]]
* HeightAngst: A large part of the series, with the male and female protagonists being very short and very tall respectively. It doesn't help that several characters are a ShipperOnDeck for them.
* HotTeacher: Maitake, in ''spades''.
* HugeSchoolGirl
* ImagineSpot: Used to great effect in the anime.
* InnocentlyInsensitive: Chiharu and Suzuki to Otani and Risa. They both start talking about how comfortable they are with the main characters, but they accidentally offend them. They both state that since Otani and Risa are about the same height as their RomanticFalseLead, they don't see them as a boy /girl. These comments almost cause them to a HeroicBSOD.
* InsultOfEndearment: [[HugeSchoolgirl Koizumi]] and [[TheNapoleon Otani]] refer to each other as "midget" and "amazon" or "totem pole" respectively. Later, after the [[spoiler:RelationshipUpgrade]], they still occasionally call each other this, though in a considerably softer manner than before.
* InstantFanClub: Koizumi starts one for Maitake.
* IWantMyBelovedToBeHappy: Abe is in love with Kohori who is in love with Koizumi. Rather than being happy that her rival is preoccupied with Otani, Abe tries to convince Koizumi to date Kohori [[spoiler:by trying to start a fight so that she'll break up with Otani and be free.]]
* JerkAss: Koizumi's grandfather, "Jii-chan," who gives Otani nothing but hell from the second the two meet, to the point of [[spoiler:arranging for a vicious gold-digger to seduce Otani away from Koizumi and break them up. She hits the wrong target, but the fact that he tried is bad enough]]. Possibly upgrades to JerkWithAHeartOfGold when he reveals [[spoiler:that his late wife was even taller than him, and the height disparity caused their relationship a lot of trouble, so he doesn't want to see the same thing happen to Koizumi]]. Possibly.
* JerkWithAHeartOfGold: Otani.
* KansaiRegionalAccent: Most of the cast. Most noticeable when Otani and Koizumi are bantering, as the staple FangirlJapanese word "baka" is replaced with "ahou".
** The series is interesting for both playing the dialect completely straight (as an aspect of the region rather than the characters in general), but also playing the [[TheIdiotFromOsaka character trope]] completely to the hilt. Aside from the "manzai duo" of the main couple, they go to freaking ''Maido Academy''. ''Maido''... really.
* KaraokeBox
* {{Kimodameshi}}
* LeaningOnTheFourthWall: Generally, the narration boxes in the manga belong solely to Koizumi's thoughts. Once in a while, some pop up that seem to belong to Otani... except the "camera" then pulls back to reveal that one of their friends is holding up a sign and a marker.
-->'''Otani''': What are you doing?
-->'''Nakao:''' (''holding up a marker and a sign next to Otani's head that says "I'm sorry for being mean to you."'') Your true feelings.
* LoveDodecahedron
* LuckyCharmsTitle: ''[[LovelyComplex Lovely]]?[[LovelyComplex Complex]]'' or ''Love?Com''.
* MatchmakerCrush: The 'matchmaker' part takes place in the first episode when both of them try to fix each other up with two of their friends (said friends end up together at the end of the episode). The crush part comes later.
* TheMatchmaker: Everyone for Koizumi and Otani, but especially Nobuko.
* MeaningfulName: Inverted with Koizumi and Otani.
* MistakenForCheating: [[spoiler:Koizumi, during several events involving her coworker Kohori. Later thought of Otani when he spends the night with a gold digger]]
* NoGuyWantsAnAmazon:
* NoodlePeople: Even Otani looks noodly sometimes.
* {{Nosebleed}}: A RunningGag with Suzuki in the movie.
* NotWhatItLooksLike: [[spoiler:Otani and Koizumi's first 'kiss' was a result of him passing out and falling on her face.]]
** Also, Otani coincidentally spotting [[spoiler:Kohori attempting to kiss Koizumi in her sleep.]] It's one of the first events to ''seriously'' test their relationship.
* ObliviousToLove: It's truly frightening how hard Otani has to be clubbed across the head with Koizumi's interest. She confesses to him, and he thinks it's a joke. A friend says that, yes, she meant him. He says, "Don't lie." When he asks what the guy she loves is like, she describes him perfectly, and [[ObliviousToHisOwnDescription he guesses she means another member of the basketball club]]. [[spoiler:It takes her repeating that description and saying, "He's in here," when they're ''in a room alone together'', and he still doesn't get it until he's had a good long think about what she's said.]] WhatAnIdiot.
* OneHeadTaller: Koizumi and Otani, though in this case it's the girl who's taller.
* PatientChildhoodLoveInterest: Mimi
* TheReasonYouSuckSpeech: Koizumi deals those to both Otani and [[spoiler: Mimi.]]
* TheRival: Mimi .
* RomanticFalseLead: Chiharu for Otani and Suzuki for Risa.
* SchoolFestival
* SecondYearProtagonist
* SexyManInstantHarem: Maitake.
* SheIsNotMyGirlfriend: Both Otani and Koizumi say this, [[spoiler: even ''after'' the former has kissed her of his own accord.]]
** There's more! [[spoiler: After they get the RelationshipUpgrade, when Koizumi is asked if Otani is her boyfriend, she says he isn't, ''because he didn't say they were a couple!!'']]
* ShipSinking: Done quite literally in the first episode with Risa's and Otani's crushes.
* {{Shojo}}: Though it tends to make fun of itself more often than most
* SickEpisode: Otani gets sick, Risa helps him out.
* SickeninglySweethearts: Nakao and Ishihara.
* SlapSlapKiss: Otani and Koizumi, of course, but [[spoiler:Maity's fiancee Jody]] and her father take the cake for this one. They beat each other senseless right before her wedding, as he didn't approve of the man she chose, but treat it as a perfectly normal occurrence and take it more as an expression of their deep love.
* SleepCute: The night before Otani's college entrance exams, everyone in his house comes down with the flu. To avoid catching it himself, Otani spends the night at Koizumi's house. He falls asleep studying, and when Koizumi goes in her room to check on him, she falls asleep next to him.
* StaringKid: Otani attracts a crowd of them after making a scene during the BeachEpisode.
* StringyHairedGhostGirl: Koizumi plays one in the haunted house during the culture fest episode, and is so incredibly good at it (due to channeling her resentment at Otani) that nobody wants to come unless she's there.
* ThereIsOnlyOneBed: At Maity's wedding, Otani and Koizumi are given a room with a double bed to share. This causes Koizumi a significant amount of angst, though Otani eventually decides to sleep down the hall.
* TinyGuyHugeGirl: Much to both Koizumi and Otani's irritation. One interesting twist on the trope is that short Otani is an athletic basketball player (and later team captain), while tall Risa is rather gangly and awkward, and not very good at sports.
* TotallyRadical: The official translation of the manga by Viz Media. Includes copious amounts of the word, "dude."
* {{Transsexual}}: [[spoiler:Seiko]] is an EPIC version of this trope. Notable in that all the characters are pretty unbothered by it, after the initial surprise.
** TransEqualsGay: The character themselves, however, is an EXTREMELY unrealistic portrayal.
* {{Tsundere}}: Koizumi comes pretty close at times
** Otani is much more so. A rare male example.
* UnlimitedWardrobe: In the manga, at least, everyone seems to have a new outfit each day. Even in school, where you'd be expecting the usual [[SchoolUniformsAreTheNewBlack Japanese high school uniform]]. Koizumi also has quite a few unique hairstyles.
* UnluckyChildhoodFriend: Haruka. He frequently sulks about it.
* UnrequitedLoveSwitcheroo: Played with, as [[spoiler: Otani starts realizing he has feelings for Risa just when she's deciding to give up on him for the last time.]]
* UnsettlingGenderReveal: [[spoiler:Seiko]]
* ViewersAreGoldfish: The anime suffers from this. ''Badly.'' In episode 13, when Risa goes to Otani's house when he's sick, [[spoiler:his fever spikes and he passes out, falling on her face and accidentally kissing her.]] Twenty seconds later, she has a flashback about what just happened.
* VitriolicBestBuds: Koizumi and Otani, ''so much'', before either even begins [[AwLookTheyReallyDoLoveEachOther thinking of the other as potentially date-worthy.]] They actually fit every single aspect of this trope, up to Otani freaking out because Koizumi thanked him for a drink instead of snarking back at him.
** Haruka and Seiko probably also qualify.
* VocalDissonance: When crossdresser [[spoiler:Seiko]]'s voice changes at the end of his second year, he becomes despondent and refuses to wear girls' clothes because his new deep voice doesn't match with a cute appearance. [[spoiler:Lucky for him, it was just a cold and his voice went back to its usual higher tone.]]
* [[WhenSheSmiles When He Smiles]]: When Chiharu promises Suzuki that she'll wait for him ([[spoiler:to enter the same university as her]]), the latter smiles. Everyone (except Chiharu) remarks how they've never seen him smile before, especially in such an adorable manner.
* WholesomeCrossdresser: [[spoiler:Seiko]] again.
* {{Yandere}}: Mimi, though she gets better.
* YourSizeMayVary: Though their stated heights ''should'' result in Koizumi being consistently OneHeadTaller than Otani, especially given that she often wears small heels (despite complaining about her height), he's often drawn to be at least as tall as her nose, sometimes with the top of his head level with her eyes, even though he's not wearing elevator shoes. The only time their heights are truly as exaggerated as they should be is when it would be conveniently [[RuleOfFunny hilarious]] or relevant to the plot - for example, Otani needing to stand a step or two higher on a staircase in order to [[spoiler:kiss Koizumi.]]
