- Alternative Character Interpretation: There is frequent reader debate over whether Takagi's antics tread into abuser territory. She sometimes engages in mild gaslighting to confuse Nishikata, as well as putting him in positions where she has power over him, then "letting him off the hook." These are tactics often used by abusers to "ease in" a victim toward more serious domestic abuse. Although all scenes from her point of view indicate she's benign, some of her interactions would ring alarm bells to an abuse counselor.
- Big-Lipped Alligator Moment: Sanae, Mina, and Yukari's segments in the anime rarely if ever impact the main plot of the episode and shift the genre of the anime into a Schoolgirl Series. This is because the characters are actually from another manga, Ashita wa Doyōbi (Tomorrow is Saturday) by the same author set in the same universe, which the anime merged into this series plot. The segments feel like a completely different story because they actually are.
- Cliché Storm: Mostly due to the series being Strictly Formula: Nishikata has a plan against Takagi -> tries to exact it -> Takagi outsmarts Nishikata somehow -> Nishikata blushes. Those who dislike the format accuse it of not trying anything new, save for the rare moments he catches her off guard. This sentiment has carries over to (Moto) Takagi-san.
- Ensemble Dark Horse: Kimura secures this position for himself following the airing of episode 12 of Season 2, when he helps a separated Nishikata meet up with Takagi. Comments about the episode are dominated by lines like, "Kimura...you're one heck of a guy!" or "Today's MVP is Kimura for sure!"
- Fandom Rivalry: With Don't Toy With Me, Miss Nagatoro, a manga with a similar premise, but with a Loving Bully instead of a mere teaser. Fans of this series will often say that Nagatoro goes too far with how she teases the male lead, while fans of the latter will claim that Takagi's coyness is more dishonest than Nagatoro's approach.
- Hilarious in Hindsight: Chi may not have a spinoff of her own, but Soredemo Ayumu wa Yosetekuru, made by the same author, features two characters that act just like her and her crush but in a Sempai/Kohai relationship.
- Memetic Mutation:
- Takagi's Forehead of Doom is something people really like to make fun of. It has also lead to comparisons with Jack Douglass, whose forehead is also the subject of many a joke.
- Takagi-san, Queen of Smug.
- Since the "Typhoon" segment in Episode 8, it became popular to depict Takagi as Megumin from KonoSuba due to having similar mannerisms when "controlling" the wind and both characters being voiced by Rie Takahashi.
- "Your overconfidence is your weakness". Regarding to Nishikata being too stubborn with himself which always leads to his loss.
- Memetic Troll: Takagi is one of the most famous anime trolls in The New '10s alongside Raphiel.
- Never Live It Down: For detractors of Takagi's pranks on Nishikata, the time she intentionally tutors him the wrong answers for an upcoming test. The fact that she did this knowing full in well that Nishikata had told her he'd get in trouble with his parents if he failed, made this particular prank rather mean-spirited. As such, detractors believe that whenever Takagi pranks Nishikata, she does it so she can toy with him.
- Ron the Death Eater: There's a running joke on /a/ among some fans that Takagi really doesn't love Nishikata and is just toying around with him. Even the Time Skip isn't safe from this, with the theory going that Takagi made him raise another man's child and never told him the kid isn't his, given that her daughter shared an overwhelming resemblance to her (and that being just as unlucky and making the same expressions are the closest things that indicates Nishikata as being the father after all).
- Sweet Dreams Fuel: As a whole, the series slow build-up of Nishikata and Takagi's relationship, combined with the relaxed atmosphere, makes for a very comfy read.
- They Changed It, Now It Sucks!: Netflix's decision to replace the Funimation English dub cast with a Los Angeles-based cast for Season 2 was met with backlash by those who watched Season 1.
