Haruna Nagishima focused heavily on playing softball all through middle school, but her love of shojo manga led her to wanting a romance of her own come high school. However, given her total lack of attention to style and flirting situations up until high school, she's an utter train wreck in trying to find a guy. Her best friend, Mami, points out that when she had similar problems in softball, she got better via advice from a coach. Haruna, instantly seeing the wisdom in this, thinks immediately of the perfect guy to ask, one who helped with her shoe when it broke the other day.

Enter Yoh Komiyama. A DeadpanSnarker that all the girls watch from a distance, he is said by everyone close to him to know what style works for anyone. He's like a Japanese schoolboy Simon Cowell, with the addition that girls just typically annoy him. Haruna's insistence wins him over, and he agrees to coach her on one condition: she can't fall in love with him.

Just how long do you think that will last?

By artist Kazune Kawahara, the series ran for about five years. A live-action film adaptation was released on April 1, 2011.

!!This series has examples of:

* ActionGirl: While not actively on a sports team anymore, Haruna still exercises regularly, goes to batting cages to clear her head, and sees no problems jumping down a full flight of stairs to catch up with people. After physicals are done, she's shown to be the strongest girl in her whole school in all categories. [[spoiler: Yoh speculates that he stops getting girls approaching him because they're afraid of Haruna.]]
* AdaptationDyeJob: Not just a dye job, actually. Compare [[http://cdn.myanimelist.net/images/characters/14/42200.jpg the Fumiya from the manga]] to [[http://4.bp.blogspot.com/_TOmy2IqK-yA/TN-705l8wNI/AAAAAAAACDY/qijn_UqtxSM/s1600/20101112_koukou1.jpeg.jpg the Fumiya from the]] LiveActionAdaptation.
* AllMenArePerverts: Haruna worries about this after reading some of her younger brother's magazines [[spoiler:when she's just innocently invited Yoh on an overnight trip.]] Fortunately for Haruna's nerves, [[spoiler:Yoh manages not to live up (or down) to the stereotype.]]
* AloofBigBrother:
** Yoh can be like this to Asami sometimes.
** [[spoiler:Miyabi]] is a gender-flipped example. She is bitter, rude, and hates her younger brother Akito for getting special treatment because he was "cuter" than her. As a result, Akito blames himself and is convinced that if he was never born, maybe his sister would have been a nicer person.
* AManIsNotAVirgin: Averted. [[spoiler:Yoh tells Haruna during the overnight trip that he's never been with another girl.]]
* BishieSparkle: If Yoh isn't actively scowling, he's emitting these. Asaoka and Fumiya also have them occasionally.
* BlueWithShock: Haruna's standard reaction when she finally realizes something. She even does this on the cover of one of the volumes.
* CanNotSpitItOut: When Haruna ''does'' finally realize she's fallen for Yoh ([[spoiler:it takes two full volumes]]), she tries to hide it because she's afraid, due to his "no falling in love" condition, she will lose him entirely if she confesses.
* ClassTrip
* CrouchingMoronHiddenBadass: Go ahead, just ''try'' mistreating a girl in Fumiya's presence. Also his BerserkButton and, in the present time incident involving Asami, a CrowningMomentOfAwesome and CrowningMomentOfHeartwarming.
* CryingWolf: Asaoka is rarely serious about anything he says and makes promises only to manipulate a loophole in his words. So when he [[spoiler:confesses to Haruna, even after promising Yoh he wouldn't]], she just smiles at him and says, "I'm not falling for that!" Possibly subverted, since there's no way of knowing if he was being honest.
* DeadpanSnarker: Yoh. In fact, Haruna gets worried about him when he stops snarking.
* [[DefrostingIceQueen Defrosting Ice Prince]]: Yoh mellows consdierably after spending more time with Haruna.
* DirtyOldMan: Haruna's second-year teacher is rumored to be one, as she notes that several pretty girls are placed in the front row. Haruna then notes that she got placed near the rear of the class. He's also disappointed when Haruna gets picked to be class representative.
* TheDitz: Haruna is pretty spacey, but even she's not as bad as Fumi, who's described as the most clueless person on the planet (Haruna being a close second).
* [[DoesNotKnowHisOwnStrength Does Not Know Her Own Strength]]: Haruna is a milder case, and usually for side gags. She seems blissfully uncaring about the fact that she tops all of the female strength tests during her physical, hurts Asami when she demonstrates the difference in their grip strength, and nearly knocks the wind out of Yoh at one point when she playfully slaps him on the back.
* TheGadfly: Asami. And how! The girl goes out of her way to provoke 'interesting' reactions from Haruna, mostly out of jealousy for stealing away Yoh's attention.
* GenericCuteness: Haruna is supposedly plain-looking.
* {{Gonk}}: Haruna's second-year teacher.
* GraduateFromTheStory
* HotBlooded: Haruna, and it's even noted that her body temperature is similarly warm.
* IWantMyBelovedToBeHappy:
** Haruna eventually gets over Fumiya and quickly grows to support his relationship with Asami.
** Subverted. [[spoiler:Asaoka decides not to confess to Haruna, only to do so, but she doesn't take him seriously because he's always such a joker.]]
* IdiotHero: Haruna, who will fall for any trick pulled on her and who misses the bleedingly obvious, like [[spoiler:how Yoh actually falls for her first]].
* InformedAttractiveness: Several of the so-called "cute" characters (most notably, Leona) don't appear all that attractive. This may be ValuesDissonance, though--maybe the "so much eyeliner, she looks like a raccoon" look is popular in Japan right now.
* [[BigBrotherInstinct Little Sister Instinct]]: Though she may not always show it, Asami genuinely cares about Yoh and is protective of him.
* LockedInAFreezer: A mild example. [[spoiler:Leona locks up Haruna and Yoh, hoping they'll quarrel over the meager resources and break up as a result.]] It doesn't work.
* LoveBubbles
* LoveTriangle: One pops up a little less than half way through the manga [[spoiler:between Yoh, Haruna, and Asaoka--who may or may not really be in love with Haruna.]]
* MenAreStrongWomenArePretty: Reversed. Haruna is noted for her physical strength, while Yoh is noted primarily for his looks.
** But typically played straight in the selection of class captains for the Sports Festival. It's a "beauty contest" for the female captains, while the male captains are usually rugged sporting types. [[spoiler:The other male captains are shocked when Yoh is selected to represent his year.]]
* NoGuyWantsAnAmazon: Haruna worries about this and tries to hide her physical competence at one point.
* {{Otaku}}: Haruna's kohai still tell stories about her binging, buying ten manga in a single visit. She's also obsessive about studying very hard on whatever she's focused on--whether it be softball or finding a boyfriend [[spoiler:or going on dates.]]
* SchoolFestival
* SecondLove: Haruna falls for Fumiya before realizing she's developed feelings for Yoh. [[spoiler:Also, Yoh towards Haruna.]]
* SiblingYinYang:
** Yoh and Asami, though they have their {{not so different}} moments.
** Akito and [[spoiler:Miyabi]]. They look nothing alike and act nothing like.
* TomboyAndGirlyGirl:
** Haruna becomes close friends to Yoh's sister Asami, who is rather feminine.
** Also, [[spoiler:Yoh's first girlfriend, who ends up asking Haruna for advice on how to get Yoh back, has this dynamic with her.]]
* StalkerWithACrush: Miyabi ends up becoming this towards Yoh after her resentment turns to affection.
* SugarAndIcePersonality: Yoh.
* TemporaryBulkChange: When Haruna is led to believe that [[spoiler:Yoh wants to break up with her,]] she starts eating huge amounts of food and appears quite rotund for about half a chapter. In the next chapter, she is seen jogging in a "sauna suit" to work off the weight and already appears normal.
* TwoTeacherSchool: Heck, a teacher isn't introduced at all until Haruna reaches her second year. That said, most of the in-school scenes happen at lunch or between classes.
* UnknownRival: Leona, who played on a rival softball team that couldn't get past Haruna's pitching, ends up at the same high school as everyone else and constantly tries to challenge Haruna. While Haruna is well aware that Leona wants revenge (well, eventually is well aware), she's blissfully ignorant of how obsessed Leona is with topping her.
* UnwantedHarem: Surprisingly, ''Haruna'', of all people, gets one when three first year boys--a mute {{bishonen}}, a {{delinquent}}-looking ladies' man, and a Yoh {{fanboy}}--each take an interest in her.
* TheVoiceless: Akito. [[spoiler:He finally talks in Chapter 39.]]
* [[ArtisticLicenseBiology You Fail Biology Forever]]: InUniverse example: A first year boy kisses Haruna, sending her into [[HeroicBSOD catatonic depression]]. He comes to school the next day with his head shaved, asking Yoh to hit him, and promising that he'll take responsibility if she's pregnant.
