A second season has been [[https://twitter.com/bokuyaba_anime/status/1670113575330025472?s=46&t=Z_Eu6mlSnrMR5VAvdA0KqA/ announced]] for 2024. The English dub premiered on August 26, 2023.

-->'''Moe''': ''I'm never covering for you too again!''

* OppositesAttract: Ichikawa is nearly about the size you’d expect from a middle schooler, while Yamada has been incredibly tall for her age since elementary school. Ichikawa is pessimistic, sarcastic, shy, diligent, and very observant. Yamada is outgoing, ditzy, prone to teasing, clumsy and it tends to take longer for her to read the room. He spends his time isolated and his interest lies in the macabre, while she spends time chatting with her friends or eating sweets. On a narrative level, Ichikawa's thoughts are presented to the audience as a show of how methodical he is, while Yamada’s are strictly ShowDontTell showing her simple yet ambiguous nature.

* TheQuietOne: Ichikawa doesn't actually speak that much early on outside of his monologues. His teacher is impressed that he spoke more than usual when getting Anna out of a bind, and Moeko is surprised that he talks at all. He becomes more comfortable with speaking over time, which led to Chii lampshading how he mutters as [[LeaningOnTheFourthWall though he's talking with squiggly speech bubbles.]]

** Ichikawa and Yamada growing closer is visualized via their distance in the library. Yamada is always seated at a table while Ichikawa starts off standing behind the library's bookcase reading a book (Or just pretending to read). Then he shifts to him standing across from her, coming closer to the point of talking distance, and finally sitting right next to her in Karte 35. There's also an extra chapter highlighting it, with Yamada herself lamp-shading how close he's gotten over the semester.
*** This also applies to their positions in class. The story starts with them sitting far from each other with Yamada in Ichikawa's line of view. Then after basically becoming friends, the class changes seats and they sit criss-crossed. [[spoiler: During their 3rd year, they end up seated next to each other thanks to Hanzawa immediately trading seats with Yamada [[ShipperOnDeck for reasons.]]]]
** The illustration for Karte 60 show Ichikawa and Yamada seated next to each other enjoying a moment. With a shadow looming over Ichikawa holding his phone, [[spoiler: hinting at the upcoming riff between them.]] Karte 63 features a similar cover of them seated [[spoiler: at Yamada’s apartment, this time with a shadow over her when she shares her childhood, insecurities and the source of her GuiltComplex.]]

* Besides TheTag, "Twi-Yaba” starts with a segment of Ichikawa struggling to greet Yamada in the morning and it ends with a segment of Ichikawa struggling to say goodbye to Yamada.

A SpinOff called “Tsuiyaba, or "Twi-Yaba”, was [[https://bokuyaba-anime.com/news/detail/?id=1111883 announced]] on October 2023; adapting the many extra chapters posted on Norio’s Twitter Account.

Kyōtarō Ichikawa is utterly convinced he is the tortured main character of a "fearsome psycho-thriller" centering on "the dark side of adolescence." A recluse and isolated from the rest of his classmates he spends his days fantasizing about ways to destroy the peaceful junior high life his classmates share. Surely this is a tale of a person at the very bottom caste of his school, who hides murderous impulses that lurk at the very bottom of his soul...

* RunningGag: Moeko expressing that she wants a “Boyfwiend”, followed by Chii and Yoshida not caring.

* {{Chuunibyou}}: Ichikawa has this '''bad''', often having "dark" thoughts about his classmates and life in general. Justified because he actually '''is''' a middle school student.

* EyeScream: Yamada tries to put glasses on Ichikawa’s face in Extra 54.2. But she ''also'' wants to surprise herself and keeps her eyes closed-shut while doing it, resulting in ''him'' getting poked in the eye by the temple.

** To her initial confusion, Yamada cries from anxiety while shooting a movie scene where she acts out as a rebellious daughter. [[spoiler: She confides to Kyōtarō later on that she may have been unknowingly drawing inspiration from her own admitted anxiety around her parents during her stay over at his house.]]
* IndirectKiss: Yamada gives Ichikawa some medicine for a headache. When he reaches the sink for water to drink the pill, he sees a cup already wet, checks the pack to see a pill missing and realizes Yamada already drank from the cup. He ''almost'' forces himself through it until he hears Yamada suddenly get up and leave the infirmary, swallowing the pill down his throat dry with a startled gulp.
* InjuredLimbEpisode: The Ichikawa family's trip to Akita in Karte 50 is cut short after Kyōtarō suffers a nasty fall exploring the woods, fracturing his right arm. He spends the rest of the winter break and the start of the next semester with his arm in a sling and has to adapt to using his non-dominant hand for everything.

* MeaningfulEcho: Kyōtarō overhears Anna rehearsing a [[spoiler: LoveConfession scene from ''Kimi Iro Octave'' for an audition for its live action adaptation, though she says it with a lack of zeal due to her conflict between going for the audition and attending the school trip to Nara with Kyōtarō. Her own confession for Kyōtarō is modeled after her rehearsal using the same dialogue. Not only does she say it with more confidence, but she also switches out “I like you” with;]]

* NotSoDifferentRemark: Ichikawa usually thinks to himself in moments with Yamada; that for all their differing traits on the surface, they have similar doubts and worries.
** When Yamada glares at Moe in Karte 31, Ichikawa internally notes he's familiar with those murderous eyes.

** He bought a dog souvenir from Akita to give to her In Karte 51, knowing she likes dogs. When he meets Yamada again next chapter he gets cold feet, considering giving a girl a souvenir as something heavy and that him knowing she likes dogs is "creepy". Ichikawa also brought back her muffler from their last hangout, only for Yamada to confess that she wanted to give it to him as a gift but didn’t think he would like it. This is what makes him hand over the souvenir while noting that they're a bit similar.

* SerenadeYourLover: Played With in Karte 127. [[spoiler: Ichikawa doesn’t sing the song ''Moving Forward''. Kana does. The song ordinated from him writing down Yamada’s LoveConfession on a note in the first place before Kana used them as inspiration (read: basically just copying) for lyrics. Kyōtarō adjusted the song further before the show and made it into a love letter to Yamada.]]
* SingleTargetSexuality: Both Ichikawa and Yamada pretty much only have eyes for each other. Yamada is the only person Ichikawa actually interacts with regularly, while Yamada often seeks him out.

* StarCrossedLovers: Discussed. When Kana brings up the idea of the two’s "hearts changing" as they grow up, Ichikawa immediately thinks of Yamada’s modeling/acting career and becomes fearful of them growing apart. Especially after hearing her affirm that she loves it. When Yamada invites him to watch her during work, Ichikawa goes along to defy this trope and learn more about her.

* ThenLetMeBeEvil: The focus of the earlier part of the manga, as Ichikawa keeps repeating to himself that he'll do something "evil" to his classmates or to Yamada. Of course, it's all talk.

** To her initial confusion, Yamada cries from anxiety while shooting a movie scene where she acts out as a rebellious daughter. [[spoiler: He confides to Kyōtarō later on that she may have been unknowingly drawing inspiration from his own admitted anxiety around his parents during her stay over at his house.]]

* PaintingTheMedium: [[spoiler: Under Nigorikawa Lucifer's influence]], Ichikawa's narration boxes are inverted into black space with white text.

* ShowWithinAShow: '' Kimi-Iro Octave'' or ''Your Color's Octave'', a shoujo romance manga that Yamada reads (And the only manga she seems to read). Ichikawa becomes a regular reader after she loans her books to him. Certain scenes in the series are used as parallel to Ichikawa and Yamada's growing relationship. The female lead is an identical clone of Yamada and the male lead Nigorikawa shares a significant number of Ichikawa’s personality traits (Which he subconsciously denies). Nigorikawa himself eventually manifests into a psychological representation of Kyōtarō’s growing self-esteem and true desires.

** Yamada sticks some chocolate paste on Ichikawa’s mouth and draws a heart at the corner of it before leaving. Ichikawa then buys a box of MeltyKiss and gives it to Yamada on his way home, reminding her that she said she was a boy at school.

** The covers of both Karte 40 and Karte 121 show Ichikawa and Yamada in the storage room. [[spoiler: Only 121 shows them as more physically developed and intimate.]]

* BreakingSpeech: An extra from Karte 85 reveals that Ichikawa did this in 4th grade to another student named Hosaka, who denied going out with Moeko and called her a hag. After seeing her crying, [[spoiler: Ichikawa confronted the boy and told him that he would be financially ruined with defamation charges, forcing Hosaka to apologize to her while bawling his eyes out. [[EveryoneHasStandards Present! Moe actually calls Ichikawa scum for this when she finds out.]]

* AnguishedDeclarationOfLove: [[spoiler: Kyōtarō cries from anxiety while finally confessing to Yamada, in addition to convincing her to a movie audition she wanted.]]

* ArentYouGoingToRavishMe: In Karte extra 109.1, Yamada fakes sleeping near Ichikawa and gets annoyed when he figures it out. She tells him to “do something”, but he thinks she’s talking about some kind of gag. [[SureLetsGoWithThat She just rolls with it.]]
* ArmorPiercingResponse: While giving Yamada a ride on his bike, Ichikawa stops at a traffic light before the local police station and [[MrImagination imagines getting busted by the police for two-person bicycle riding, along with his and Yamada’s reputation suffering and Yamada losing her part-time modeling job.]] Before he can bring it up she asks if he prefers chocolate or calpis-flavored Papico. His answer, chocolate, apparently means he’s the type who fears change. Ichikawa then decides to just ride past the station with her anyway.
** In Karte 63, [[spoiler: Yamada admits to Ichikawa that she constantly worries she's making her friends upset, and that they just aren't telling her out of politeness. Ichikawa tries to reassure her that he's not like that and that he'd have no problem speaking up and being [[BrutalHonesty brutally honest]] with her if she ever did something he didn't like. Yamada then brings up how [[CallBack he started avoiding her in the days leading up to the winter break]], and expresses doubt that it was really just because he was busy like he said. Ichikawa, who had been giving her the silent treatment over a misunderstanding, then lied about it afterward to avoid hurting her feelings, is caught completely off guard and can only apologize and confess he's not as strong as he makes himself out to be.]]

* BeCarefulWhatYouWishFor: While still within his “murderous-urges” phase, Ichikawa mused in chapter 1 about seeing Anna’s “beautiful face contorted in pain”. The sight of her suffering from a nose injury horrifies and hurts him almost as much as it does her.

* CutenessProximity: Ichikawa becomes so enamored by [[spoiler: Yamada’s new blonde-hair color]] that his inner monologue devolves into jumbles of connected words before finishing at "CUUUUTE!!!"

* GoneHorriblyRight: In Karte 115, [[spoiler: Ichikawa starts to worry that his family may have seen the piece of paper he wrote Yamada's LoveConfession down on, and tries to cover for himself by claiming that he's been writing song lyrics. Unfortunately for him, Kana happens to be struggling to write a new song for her band at the time, and begs Kyōtarō to show her his "lyrics" for inspiration. When he finally relents, she thanks him by giving him two tickets for her next show, meaning Yamada will be one of the first people to hear a song very obviously based on her own confession]].

* MeetCute: Played with. Yamada and Ichikawa are classmates, but apparently didn't really interact much until he happened to walk into the library when she was stuffing her face. He also lent her a retractable knife when he saw her trying to work on a class project (In an amateurish manner. She tried ripping the paper with her barehands before he handed his knife over.)

** When Yamada asks (over text) what Ichikawa said about her to his sister, he tells her that they’re friends... “at least for now.” Ichikawa meant that ''that’s'' the explanation what he’s going with. Yamada focused on the “for now” part, assumes he’s talking about a future RelationshipUpgrade and gets giddy.

* ThePowerOfLove: Ichikawa has pushed himself to do things that he’d consider impossible for him and out of his comfort zone, even on a subconscious level where his body moved and/or his mouth opened in dissent with his thoughts. Because Yamada was present and he desires and values her company that much. [[spoiler: He realizes this by Karte 124 and tells Yamada as much when she apologizes for “bothering” him (texting for his opinions on swimsuits she’s shopping for) while he’s studying, likely worried about her GuiltComplex.]]

* OhCrap: Ichikawa in Karte 60, when he absentmindedly shows Anna [[spoiler: the picture he took of some snowy scenery (Which he said he would take for her on his trip to Akita) right before he fell and broke his arm. He initially thought they could laugh over it [[ItsAllMyFault until he saw the horrified look on her face.]]]]
** Karte 68; basically everyone's reaction to the presence of [[spoiler: Yamada's [[FaceOfAThug father.]]]]

* OppositesAttract: Ichikawa is nearly about the size you’d expect from a middle schooler, while Yamada has been incredibly tall for her age since elementary school. Ichikawa is pessimistic, sarcastic, shy, diligent, and very observant. Yamada is outgoing, ditzy, prone to teasing, clumsy and it tends to take longer for her to read the room. He spends his time isolated and his interest lies in the macabre, while she spends time chatting with her friends or eating sweets. On a narrative level, Ichikawa's thoughts are presented to the audience while Yamada’s are strictly ShowDontTell.

[[https://bokuyaba-anime.com/ An anime adaptation]] by Creator/ShinEiAnimation premiered on April 2, 2023. Available for streaming on [=HiDive=]. A second season has been [[https://twitter.com/bokuyaba_anime/status/1670113575330025472?s=46&t=Z_Eu6mlSnrMR5VAvdA0KqA/ announced]] for 2024. The English dub premiered on August 26, 2023.

* AccidentalPervert: Discussed when Adachi feels the need to ask an editor for Akita Shoten [[AskAStupidQuestion to what degree lucky lecher moments have a basis in reality]] during a class trip. Ichikawa also has his fair share of inadvertently finding himself creeping on Yamada, but it's implied that Yamada is every bit as self-conscious about her own attraction to Ichikawa.

* GuiltComplex: Yamada will feel immediate guilt and responsibility for any inconvenience that she even thinks she causes others. At most she's quick to apologize. At worst, and sadly quite often, she'll break into tears. This applies even if it's not something she actually did and someone's doing something on her behalf, such as Ichikawa [[spoiler: getting his arm in a cast while taking pictures of snowfields in Akita for her, which he proposed. She later admits to developing a fear of her friends and loved ones eventually hating her from a history of many screw-ups.]]

* HeldGaze: While forced against each other while riding an elevator with so many people, Ichikawa keeps his eyes closed so that he wouldn’t have to stare at Yamada for too long. By the time he hears the ding, he opens his eyes and sees Yamada staring into his face even after the other occupants left.

** It also goes both ways. Ichikawa gives her an ear stimulation when he was just trying to quietly tell her to hide some candy from the librarian. And in trying to keep Yamada from seeing some magazines that she models for in his bedroom, he pins Yamada to the bed and seemingly awakens a collar bone fetish in her.

* IndirectKiss: Yamada gives Ichikawa some medicine for a headache. When he reaches the sink for water to drink the pill down, he sees a cup already, checks the pack to see a pill missing and realizes Yamada already drank from the cup. He ''almost'' forces himself through it until he hears Yamada suddenly get up and leave the infirmary, swallowing the pill down his throat dry with a startled gulp.

* InterplayOfSexAndViolence: In an omake chapter, Yamada gets Ichikawa to roleplay a zombie scenario, to which Ichikawa claims he'd shoot a zombified Yamada without hesitation even if she hasn't turned yet. Hearing this, Yamada begins slowly lurching towards him moaning. Ichikawa to his surprise does indeed hesitate, just for a second, as Yamada pulls Ichikawa in for a pretend bite. Both Ichikawa and Yamada can be seen blushing as she draws closer to his neck.

** In Karte 61, Moe comes across Ichikawa searching for “something” [[spoiler: (a doggy keychain from his family trip that he gave to Yamada as a gift) out in the snow. She says that she was on her way to Yamada’s home and allows him to come along, something that he obliges to knowing he has a better chance of finding it close to where Yamada lives at. When he meets Yamada herself, Moe suddenly gets a “call” that her brother is in the hospital and walks off. A character Q&A revealed that she forgot about her brother’s “incident”.]]

* LastNameBasis: The student cast addresses each other by their last names, as is typical of their age group. Yamada goes by first-name basis with her circle of friends, while Moe is the only one who calls her "Anna". When Yamada and Ichikawa are forced to call each other by first name, even if one of them isn't around the other, [[TwiceShy the two either stutter or get tongue-tied.]]

* NoSenseOfPersonalSpace: Yamada sometimes comes right up to Ichikawa when talking to him, often making him back up in a flustered panic. She seems to do this subconsciously, though, because on the one occasion Ichikawa walked right up to her to whisper in her ear (to warn her a teacher was coming and to hide her snacks) in Karte 37, ''she's'' the one who jolted away.

** In Karte 18, a teacher walks into the chemistry lab to find Anna [[DoesThisRemindYouOfAnything kneeling in front of Ichikawa behind a desk, coughing and covered in a sticky substance]]. Kyōtarō quickly confesses that the two of them snuck in to prepare a dessert in one of the beakers and Anna accidentally spilled it on herself, which gets them both in trouble, though almost certainly not as much trouble as they'd have been in had he not explained himself.

* TheRemake: Karte 72 adapts the events of two of the bonus Twitter comics into a full chapter with more polished artwork, with [[https://twitter.com/lovely_pig328/status/1360891870331604995 Moeko giving out friend chocolates to the boys in her class]] and [[https://twitter.com/lovely_pig328/status/1095977515452063745 Anna challenging Kyōtarō to a game of chocolate Shogi.]] Karte 73 would continue this trend, with [[https://twitter.com/lovely_pig328/status/1228264038213156866 Yamada and Ichikawa discussing what kind of chocolate you'd give to someone to tell them you love them]].

* DelayedReaction: On a walk from school in a Vol. 4 extra, Ichikawa lets Yamada touch the hand belonging to his fractured arm to see if he feels pain. Then they continue their walk and talk about the prospect of Yamada getting an injury while unknowingly holding up hands. ''Then'' they realize they’re holding hands on the next page, but neither of them bring it up or let go and continue their conversation as naturally as they can.

** Karte 68; basically everyone's reaction to the presence of Yamada's [[FaceOfAThug father.]]

** The Illustration for Karte 42 is a butterfly flying out of Yamada's hands, foreshadowing [[spoiler: the chapter's following strain in her relationship with Ichikawa. That same butterfly appears over the two next chapter where they reconcile.]]

* SayingTooMuch: On a few occasions, Chii gossips to Ichikawa about things Anna said (Usually concerning him) or did (Like her eating habits) while Yamada herself is feebly trying to get her to hush or just pouting at her.

** DoubleSubverted with Kana. Kyōtarō is worried she'll start acting like this as soon as she finds out about Anna, but when she does she assumes her brother developed an unrequited crush on a girl well out of his league, and tries to let him down gently. At least, until she realizes Yamada was the same person who came to visit him while he was sick, at which point she immediately starts pestering him to ask her out.

** When Adachi awkwardly admits to Ichikawa that he [[TooMuchInformation "can't jack off to Anna anymore"]] (while still only referring to her in sexual terms), Ichikawa wonders if he feels disgusted at the exchange because he knows he's thought about Yamada in sexual terms as well, let alone all the times it's implied Ichikawa has had to [[IllBeInMyBunk go relieve himself after feeling overwhelmed by her.]]
