''My Wife is a High School Girl'' (''Oku-sama wa Joshi Kōsei'') is a {{Seinen}} {{Manga}} series created by Hiyoko Kobayashi and published by Shueisha in their publication magazine Young Jump. The {{Manga}} ran from 2002 to March 2007 and compiled thirteen volumes over its run.

The Manga would later be adapted to a VideoGame designed for the PS2 and {{Dreamcast}}. The games were released on June 20th, 2002 for the PS2, and November 21st, 2002 for the Dreamcast.

Another adaptation came in the form of an {{Anime}}, produced by studio Madhouse under director Jun Shishido. The show's original run was on the TV Saitama network between July 2nd, 2005 and September 24th, 2005, with 26 episodes produced.

The plot of the Manga and adaptations involve Asami Onohara a seventeen-year old high-school student who is married to Kyosuke Ichimaru, her Physics teacher in the same high school she attends. However, even though they are officially a married couple, Asami's father forbids them to have any sexual contact until after Asami has graduated. The story involves the hiding of the relationship from people; specifically those of the highschool, while the couple face opposition to the relationship on behalf of Asami's father and third parties.

!!Tropes:
* AllWomenAreLustful:
** Asami, as she consistently tries to get Kyosuke to break her father's rules that forbids them from having sexual contact until she graduates from high school. HilarityEnsues.
** Iwasaki-sensei tries to tempt Kyosuke with her feminine wiles [[spoiler:[[IgnoreTheFanservice to no avail]]]]
* ChickMagnet: For someone as [[GenericGuy lampshadedly plain]] as [[TheEveryman Kyosuke]] is, he certainly had a lot of women throwing themselves at him.
* HotForStudent:
** The entire plot of the story.
** There's even another teacher guilty of this. But it's okay--the teacher was just using him so she could feel good, she wasn't going to marry him or anything. (This is exactly how it was treated in the anime.)
* IWantMyBelovedToBeHappy: Iwasaki-sensei
* JailBaitWait: Kyosuke is waiting for Asami to graduate from High School before they can have sex; it's all written up in a legal contract her father forced him to sign.
* LoveMakesYouCrazy: Iwasaki-sensei, upon realizing Kyosuke loves someone else, develops an obsession and repeatedly tries to tempt him away from his love interest. When she finds out it's a student, and they're "dating", she refuses to lose to a "little girl" and uses her authority to separate them, and blackmails Kyosuke at least twice.
* MaleGaze: And ''how''.
* MsFanservice:
** Asami, between her own erotic fantasies (and her husband's), hilarious real-life situations, and attempts to seduce her husband. Ironic in the fact that she's the only character who's off limits.
** Secondary is Sakura, who works at a night club and is anything but subtle when she wants a man.
* OverprotectiveDad: Asami's father.
* ShipperOnDeck: Her friends are ''very'' supportive of a potential hookup between their friend and her teacher crush.
* ThroughHisStomach: Played with, in that she's already married and a [[YamatoNadeshiko traditional Japanese]] wife: she sort of ''has'' to cook for him. That doesn't stop her from trying to effect some reaction from him by cooking elaborate, tasty meals.
