When Konatsu goes to look for Haruki, a member of the basketball team, she finds out that he [[GenderBender turns into a]] [[AllWomenAreLustful perverted girl]] at night. Haruki-as-a-girl then sexually harasses her, they wake up in the same bed, and Haruki admits that he knows Konatsu has a crush on the team captain. Long story short, the captain turns out to be a jerk, so Konatsu decides to go out with the ultimately well-meaning Haruki. Hijinks ensue.

!!This series provides examples of:
* {{Ahoge}}: Haruki.
* AllWomenAreLustful: Haruki's Female Self. [[spoiler:As well as his older sister.]]
* AttemptedRape: Konatsu has horrible luck with guys; every one of them save Haruki has tried this on her. Luckily Haruki is there to bail her out, usually as a girl.
* AttractiveBentGender: Haruki turns into a blond bombshell. [[spoiler:His siblings don't look so bad either, and nor does Konatsu as a boy.]]
* BelligerentSexualTension: Konatsu and Haruki constantly [[BelligerentSexualTension bicker over everything]].
* BiTheWay: Konatsu.
* CatchPhrase: "I can't control my urges," and "[[TitleDrop You're a beast!]]"
* ChainedHeat: [[spoiler:When Konatsu as a boy becomes uncontrollably horny, Megumi and Ryou decide to handcuff her to Haruki and lock them in a room. Nothing actually happens, but they do spend the rest of the chapter handcuffed.]]
* {{Ecchi}}: As a result of girl Haruki's utter shamelessness.
* FriendlyLocalChinatown: Haruki and Konatsu go here [[spoiler:since Konatsu caught Haruki's special condition, and doesn't want to go back home until she's cured.]]
* GagBoobs: The general joke is that Haruki, ostensibly a boy, has bigger breasts than Konatsu.
* {{Gayngst}}: Mostly averted. Konatsu mentions that she found herself more attracted to the female version of Haruki, though it doesn't seem to bother her too much. [[spoiler:Then when Konatsu turns into an equally lascivious boy, Haruki panics and says he doesn't want to kiss another boy. He takes it back, but by that time Konatsu [[SpoofAesop reverts to being a girl]].]]
* GenderBender: Obviously Haruki, [[spoiler:and also Haruki's younger brother, Megumi, and older sister, Ryou. Konatsu temporarily becomes a boy later on.]]
* GetAholdOfYourselfMan: Ren to Haruki, after Konatsu starts dating Jun. He may not have convinced the male Haruki, but female Haruki rushes straight to where Konatsu and Jun are afterwards.
* GirlsLove: The IfItsYouItsOkay sort, and a lot of it for a shoujo manga.
* GodivaHair: Girl Haruki, who oftens ends up bare-chested for [[MsFanservice one reason or another]].
* HotForStudent: A couple of the teachers. Neither Konatsu nor Haruki return their affections.
* HotSpringsEpisode
* IJustWantToBeNormal: Haruki. Occasionally he wonders whether he'd be better off as a girl.
* JerkWithAHeartOfGold: Haruki. As a girl he's just a LovableSexManiac.
* TheLadette: Haruki is much more aggressive as a girl.
* LingerieScene: Several, because for Konatsu, underwear is SeriousBusiness.
* MarshmallowHell: When he transforms, Haruki inflicts this generally on the unsuspecting.
* MsFanservice: Girl Haruki, definitely.
* MultipleDemographicAppeal
* OpeningMonologue: Since chapters are released irregularly, there's one at the beginning of every chapter from the POV of either Haruki or Konatsu.
* RomanticFalseLead: Several of them, actually.
* SchoolgirlLesbians: Haruki is a [[DiscountLesbians discount]] version.
* SickEpisode: In one chapter, Haruki changes genders whenever he sneezes.
* SingleTargetSexuality: Haruki.
* TheyDo: Subverted. [[WillTheyOrWontThey They try]], but they never quite seem to get there.
* TwoPersonLoveTriangle: Konatsu is never quite sure which Haruki she's attracted to, or which Haruki is attracted to ''her''. It's an ongoing part of her CharacterDevelopment.
* TheUnfairSex: Haruki probably wouldn't get away with any of the naughty things he does to Konatsu as a girl if he hadn't been one.
* UnusuallyUninterestingSight: Almost no one questions Haruki's ability to change sexes; if they do, they freak out, run away, and are never seen again.
* WidgetSeries: It's {{Ecchi}} {{Shoujo}} GenderBender GirlsLove... Who's the [[PeripheryDemographic intended audience]], again?
