- Base-Breaking Character: Anyone in the main trio:
- Suzume. Is she a fresh change from usual shoujo heroines, or is she just even more passive, slowly becoming more of a trophy to be won rather than an actual character as the series progresses?
- Shishio. Is he a selfish adult who just wants to play around with a young girl, or is he serious about Suzume and just can't express his feelings well after coming of a painful relationship?
- Mamura. Depending on who you ask, he's either one of the nicest manga boys on Earth or a misogynistic brat who only cares for Suzume because of his own purposes.
- Crack Ship:
- Ensemble Dark Horse: Yuyuka. Some fans would've preferred more focus on her than on Suzume.
- Germans Love David Hasselhoff: The series doesn't sell that well in Japan (although it's rather popular, other series ongoing at the same time such as Blue Spring Ride or Wolf Girl and Black Prince sold far better), but its overseas fanbase is huge, with the author receiving lots of questions from foreign fans in her Twitter account and a strong Tumblr fanbase. Its popularity also made possible it was licensed in four European countries before receiving an official English translation. It helps that Mika Yamamori is very invested in Western pop culture and is willingly receptive of her international fans.
- Hilarious in Hindsight: Early during the publishing of the series, Yamamori Mika did a fanart of Lisbeth Salander from The Girl With The Dragon Tattoo. Cue 2015, and Sameshiba, the new girl introduced in Shishio's special, looks a lot like her.
- Memetic Mutation: 2 beers 4 Shishio. Explanation
- The Scrappy:
- Shishio is very popular in school because of his status as the Cool Teacher, but he's sort of The Scrappy in various parts of the fandom. This is lampshaded in the crossover with Heroine Shikkaku (drawn for Margaret's 50th anniversary) where Hatori mentions that Mika Yamamori's family and assistants unanimously hate him. This leads to many Ron the Death Eater moments, with extreme Mamura fans accusing Shishio of being the cause of every problem in the series.
- Tsubomi isn't a well liked character in the fandom either.
- Ship-to-Ship Combat: The tension between Shizume (Shishio x Suzume) and Mazume (Mamura x Suzume) fans reach overwhelming levels, specially after the last chapters where Suzume starts to fall for Mamura but Shishio realizes he's in love with her.
- Squick: Some Mamura fans complain about how a relationship between a teacher and his under-aged student would be gross.
- They Wasted a Perfectly Good Character:
- Some fans consider Shishio to be neglected during the latter half of the manga, barely getting any spotlight or development and later getting paired up with a complete stranger in his special. Whether it happened to be Executive Meddling (Yamamori changed editors during the time Mamura's arc started) or if it was due to Mamura's bigger popularity is up for debate.
- Same happens to Samejima. Fan reception of her character was overall very positive, but some people think it should've been better if she had been inserted in the main story rather than being featured only on an extra.
