History YMMV / HappyLesson

* OnceOriginalNowOverdone: At the time of its original release, the series had a fairly unique premise, but nowadays, thanks to the boom of HaremGenre series, it seems like a run-of-the-mill ClicheStorm. Each character can be classified as an archetype, the plot beats can be seen a mile away, and the plot itself can be seen as rather generic.

* AudienceAlienatingPremise: The idea of a "harem of mothers" may seem off-putting to many viewers, despite the [[spoiler:initial]] absence of any romantic tension. Largely because that, while they ''aren't'' [[NotBloodSiblings actually related to each other]], the notion of a teenage guy in any kind of romantic relationship with an adoptive mother figure can easily break incest taboos.

* CrossesTheLineTwice: The abuse (sometimes accidental, sometimes intentional) that befalls Chitose is played for laughs.

* ClicheStorm: Not too much for the 2002, but is now almost on the verge SeinfeldIsUnfunny.

* {{Squick}}: The [[spoiler: Mutsuki/Chitose]] pairing has the potential to elicit this response. In addition, the idea of ​​"the harem of the mothers" may seem repulsive to many viewers, despite the absence of any romantic tension.
* StrangledByTheRedString: The [[spoiler: Mutsuki/Chitose]] pairing; not only is there no hint whatsoever of attraction between the two until the last few OVA episodes, but the entire idea of the couple is antithetical to the point of the show.
* NarmCharm: This show is a comedy, but, its bizarre animation, weird humor and reactions Chitose may themselves look incredibly narmy.

* CounterpartComparison: with LightNovel/SisterPrincess. Both series are light comedies about how lonely guy suddenly gets a large family consisting of lovely girls. Both shows are also have easy IncestSubtext, so in the first case the MC lives with twelve younger half-sisters, and in the second case, the MC is adopted by five beautiful women. The only difference is that the Happy Lesson is less focused on this, because none of the "mothers" or appearing later "sisters" is not a relative of the MC.

* UnfortunateImplications: Although its not official in a legal sense, the teachers are basically Chitose's adopted parents, which makes [[spoiler: the last minute hookup between Chitose and Mutsuki]] a little uncomfortable. Woody Allen would be proud.

** On the other hand, the two of them have a very weird sexual tension since the first time they are introduced and the line between adoptive parent/possible love interest gets hazy numerous times through the entire franchise, so in hindsight its far less creepy, though YMMV.
