* FoeYayShipping: Risa and Mimi become particularly...''chummy'' for two girls who start off as rivals in love.
* HoYay: Otani and Maity. The scene most famous is Maity blowing in Otani's ear to wake him up. The poor boy was mortified by his actions.
* MemeticMutation: AHDSAKAFAJDAGS![[labelnote:Explanation]]Haruka's reaction to learning about Risa's and Otani's relationship.[[/labelnote]]
* {{Narm}}: The scene during the class trip when [[spoiler: Otani discussed his feelings towards Risa and his reaction at finding out about her crush on him.]] It quickly turns narmy when a sobbing Koizumi runs towards Nobuko and Heikichi... screaming something about bear meat curry. Doubles more as NarmCharm regarding the [[ItMakesSenseInContext situation]].
* ValuesDissonance: A modern viewer or reader will consider Seiko a trans girl and will treat her as such, but her handling is somewhat haphazard; while she's specifically told that she's not disgusting and there's nothing wrong with her, and her femininity is encouraged by most of the cast, the subtitles and certain translations will refer to her with he/him pronouns, and call her a false woman.
