Chapter 6: I Don't Like It

**I Don't Like It** is the sixth chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

The next day, Ichikawa is riding his bike to school, his mind filled with thoughts of the Ciel magazine. He again encounters Yamada on the path to school, but next to her is a boy he does not know. Fearing that she may have a boyfriend, he walks up behind them while trying to deny his own disappointment. Yamada is playing dumb about what a LINE account is, and Ichikawa realizes that the boy is trying to pick her up. He continues to push awkward questions on her, trying to get her contact information despite her obvious unwillingness to engage with him, and she tries various tactics to draw the conversation out to where he'll leave her alone. He makes zero progress until he calls her funny, which provokes a positive reaction in her. Even so, she refuses to give him any kind of information, and he suddenly grabs her arm to provoke her. Ichikawa reacts with stunned fury as she tries lamely to break his grasp on her arm. She finally begins reaching into her skirt pocket for her phone, and in response, Ichikawa rears back and flings his bicycle forward, just as Chi runs up beside him. The riderless bike crashes into the nearby barrier, startling everyone around, and it goes sailing off over the fence and into the river. Everyone in the vicinity rushes over to look at the scene, and when Yamada asks what happened, Chi informs her that Ichikawa threw his bike forward. He denies it by saying he got his brake and accelerator mixed up, much to Yamada's amusement. She calls him funny as his bike floats in the water.

## Trivia

* This is the first appearance of Haruya Nanjou, though he will not be named properly until Chapter 42. Ichikawa usually just refers to him as Pickup-pai, a portmanteau of Pick-up, like a pick-up artist, and Senpai.

* Ichikawa recognizes that for Yamada, being funny or interesting is the highest form of praise, and she later calls him funny when she recognizes what he did to save her from giving Nanjou her number.

* The street that Ichikawa walks down is the real-world Enzan Street, found here.

## Summary

* Yamada and Ichikawa are playing with sparklers on a summer's evening. Yamada announces that the first one to fall loses, and comments that they're pretty as they go off. He grabs her hand, pushing it away and saying that they should be further apart, but as he does, her attention goes from the sparklers to his face, and she continues staring until his goes out. She declares it her loss despite this, and he asks why.
* Yamada in a public bath.
* Following the events of the previous Chapter, Ichikawa offers to walk Yamada home since it's already pitch black out, trying to act outwardly suave, but feeling internally creepy. She proposes they play Shiritori, a Japanese word-play game while they walk. When they make it to her house, she says "arigatou" in compliance with the game rules, and he replies "un," (sure) in response, losing the game.

## Trivia

The game of shiritori that they play goes: gorira, ringo, ramen jirou, miruku tii, shii-chuu, imo-mushi, arigatou, and un. In English, that is Gorilla, apple, ramen jirou, milk tea, stew, caterpillar, thank you, and sure.

Beneath this, a single panel is of Yamada and Ichikawa reacting to a baby, who was born two months ago, asking what the "Twi" in "TwiYaba" means, with them realizing there is a generation gap.

## Trivia

The bit with the baby is in reference to the acquisition of Twitter by Elon Musk and his subsequent renaming of the platform as simply "X."

## Summary

* A follow-up to Extra 104.1, Yamada is lying on her bed, taking various poses like touching her face, or fidgeting in her bed.

Possible Future Events

**This page** compiles events that either appear to happen or are potentially foreshadowed to happen in the future of BokuYaba's canon, meaning past the events of the most recent Chapter of the Manga.

* Yamada goes with the Ichikawa's to Akita during their next New Year's visit. She says she would like to go to Akita in Chapter 50. Extra 89.1 might also be showing this.
* Revisiting Enoshima. In Chapter 137 Yamada and Ichikawa say that they'll go to Enoshima again to see the same spot.
* Video games with Yuki. Yuki offers Ichikawa his Friend Code on Smitch in Chapter 98. While he has been shown playing on his device a few times in Extras, there has been no confirmed instances of him playing with Yuki, so it's likely to come up.
* Yamada's birthday. Current Chapters are set in the middle of August, meaning her birthday is just about three weeks away.
* Christmas. Extra 86.1 has to take place around Christmas. Extra 111.1 implies Ichikawa will spend Christmas, or a day close to it, with the Yamada family.
* Yamada and Ichikawa's Anniversary. Extra 122.1 shows him giving her flowers for their anniversary, which logically would take place the following year.
Extra 46.1

**Extra 46.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Taking place during the previous chapter, where Yamada and Ichikawa are still standing in line, she asks him if he knows why it's a bad idea to go to a theme park on the first date. He can't think of a reason, and she adds that it's because of the long lines causing stress and it makes the relationship worse, but she absent-mindedly adds that that doesn't seem to be true at all, in regards to their current situation. They both take a moment to consider what she just said, and he asks why that is, while she covers her mouth in embarrassment. The caption on the side says "It's safe, he didn't notice."

* In class, Moe is reading about the trashy lives of celebrities, talking about a famous man who cheated on his wife. They talk about how pretty his wife is, and how surprising it is that he'd cheat on someone so gorgeous. Moe asks Ichikawa, who has had his head down on his desk the entire time, his opinion, and while he finds the question pointless, he offers that someone who commits adultery is a "morally bankrupt douchebag." Moe makes fun of him for listening in, and Yamada reacts with happiness at his proclamation.

* Another part is Yamada and Ichikawa considering how to finish their hand-outs from Extra 44.3. Both of them are considering the "Love Corner" section, with Yamada looking away embarrassed and considering her options, while Ichikawa taps angrily at the page with his pen.

* The next page is Yamada and Ichikawa celebrating a new reprint of the manga.

* The last page is an acknowledgement from Norio Sakurai about an art mistake she made in the previous chapter, forgetting to fill in a section of Ichikawa's undershirt. She makes a hypothetical drawing of how the sleeves of the mistake shirt would look on him.

## Trivia

Yamada does not have her tights on from the previous chapter here.
Extra 88.1

**Extra 88.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* An image of Yamada on a couch, looking wistful, and holding her phone in her hand.
* An image of Ichikawa at his desk, his lit-up laptop illuminating his otherwise dark room. He has headphones on and is looking to the side, as if thinking.
* An image of Yamada snuggling with a small cat, and Ichikawa being snuggled by a huge cat, approximately a time-and-a-half his size.

## Trivia

The two cats are assumedly "cat versions" of the other character, as Yamada's cat has Ichikawa's "hair style" in the black part of the fur, while Ichikawa's cat is much bigger than him and seems physically possessive.
Kobayashi Chihiro

* Manga
* Anime

**Kobayashi Chihiro** (小こ林ばやし ちひろ, *Kobayashi Chihiro*) is a secondary character in Boku no Kokoro no Yabai Yatsu. She is Yamada Anna's close friend. She studies in Class 2-3 (later 3-1) with most of the rest of the cast.

## Appearance

Kobayashi is considerably shorter and more child-like in appearance than the rest of the girls in her friend group. She has short, brown hair and brown eyes.

## Personality

Though Kobayashi has a somewhat childish personality, she usually acts as a brash straight man to Yamada's antics, calling her out for disappearing when she should be working on something, or when she smacks herself while trying to use a fan to cool off. She also has a tendency to be oblivious of certain more "mature" things, like romance, as she seems to be the only one who doesn't realize Yamada and Ichikawa's feelings towards each other.

## Relationships

#### Yamada Anna

Kobayashi and Yamada seem to be best friends, and in a lot of ways polar opposites. She is sometimes used by other characters (namely Ichikawa) to get a feel for her mood. They have a comedy routine where the (considerably larger) Yamada uses Kobayashi as a form of transport or as furniture. Ichikawa calls Kobayashi Yamada's "boyfriend" due to their skit, which the other boys enforce by comparing her sitting on Chi's lap to them performing skinship. That said, Kobayashi often complains about Yamada's carefree attitude, and they are known to bicker with each other at times, with Kobayashi often insulting her by calling her "giant."

## Etymology

* **Kobayashi** means "small" (小) (**ko**) and "forest" (林) (**hayashi**/**bayashi**).
* **Chihiro** is written in hiragana (ちひろ), which has no special meaning. However, when written in kanji (千尋), it could possibly mean "thousand" (千) (**chi**) and "fathom, armspan" (尋) (**hiro**).

## Trivia

* Despite being a secondary character, Kobayashi, alongside Yurine Hanzawa, actually predate the entire rest of the cast in publication by at least three years, appearing in a one shot titled *With Her Eyes Half-Open.* The characters were later repurposed for *BokuYaba*.
* She is in the school basket ball club.
* Kobayashi has food allergies and cannot eat certain things, though it isn't fully mentioned what they are.
* In elementary school she had three pet goldfish named Ron, Pon, and Kan.
Extra 122.1

**Extra 122.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* An image celebrating Yamada and Ichikawa's real-world Anniversary on June 12th. Yamada is in a white dress, sitting on a green, windswept hill picking flowers, and Ichikawa, wearing a casual outfit, walks up beside her, holding a big bouquet of white flowers in a blue holder. He is picking a flower crown off of her forehead, and she is looking up at him surprise before he hands it to her.
* An image promoting Episode 11 of the anime. Yamada in her sportswear, looking intrigued.
* An image promoting Episode 12 of the anime. Yamada is on Ichikawa's bed looking happy, and his shadow is visible looming over her.

## Trivia

The bouquet of flowers that Ichikawa gives Yamada is one of White Roses, and the intended meaning behind them in Japan is innocence, devotion, and silence, while Western interpretations are virtue and chastity.
Sekine Moeko

* Manga
* Anime

**Sekine Moeko** (関せき根ね   萌もえ子こ, *Sekine Moeko*) is a secondary character in *Boku no Kokoro no Yabai Yatsu*.

Moe is a fashionable young woman with a mischievous streak. She is Ichikawa and Yamada's classmate in Class 2-3 (later 3-1).

## Appearance

Moe's design has elements of the gyaru subculture, namely her light hair color and manner of dress. She is often depicted with the anime-style "cat smile" w-shape.

## Personality

Moe has the most outgoing personality of her friend group, and she seems to act out certain "cutesy" tropes, like often referring to herself in third person, or posing on big announcements or proclamations. While she is a good friend, she enjoys messing with people, and even when she is helping this usually comes at the cost of her trolling.

## Relationships

#### Ichikawa Kyoutarou

Moe becomes a friend to Ichikawa through their shared relationship with Yamada. She teases him when he begins opening up to Yamada and her friend group, saying she was surprised he could talk, but also tries to help him get out of his shell and pushes the relationship further in a variety of ways. She calls him out for claiming that Pickup-pai is "misreading" his and Yamada's relationship, while also getting him out of a situation where he is trying to get information out of Ichikawa. She also helps to get him into Yamada's apartment by pretending to be his girlfriend, which later gets him closer to both Yamada and puts him on good terms with her mother. That said, her penchant for messing with him often makes him angry, to the point that many of their interactions are two steps forwards, one step back.

## Etymology

* **Sekine** means "barrier, gate" (関) (**seki**) and "root" (根) (**ne**).
* **Moeko** means "bud, sprout" (萌) (**moe**) and "child" (子) (**ko**).

## Trivia

* Moe is in the school's cooking club.
* Moe knows Re:Zero via her brother, who is otaku. She likes Ram more than Rem. She is also aware of various other mainstream anime, such as One Piece, HunterxHunter, and Attack On Titan, but doesn't delve too deeply into otaku culture.

He immediately rejects the idea, thinking how it's worse if a disturbed character wears them, but she insists, so she tries to put them on, stabbing him in his closed eyes. He asks why she has *her* eyes closed, and she says she wants to get the full effect when she sees it. He dodges her next attempt, then puts his hands on hers to help guide her. She chuckles at the result.

He says that if you say anything important on this day, it seems like a lie. She asks for an example, but he accuses her of playing dumb. She tells him to tell her tomorrow, then, but he ends the conversation several hours later by saying he fell asleep.
Extra 16.1

Extra 16.1 is a set of Extras in Boku no Kokoro no Yabai Yatsu. It is the first Extra of Volume 2.

Ichikawa then broods the rest of the day, while biking, bathing, and lying down to sleep, before waking up the next day, determined to say "good morning" back. She greets him as expected by saying it while prodding him in the back with her shoulder, and he gets momentarily distracted, but tries to call out to her. When she comes over, asking what's wrong, he loses his nerve, and tells her it's nothing, but this just makes her more curious. She chases him through the halls, demanding an answer, and asking if it's something he can't say in public. She then opens an empty classroom and drags him forcefully inside, blocking the door, and demanding he say it. He stammers out an clumsy "morning," causing her face to light up. Outside, she continues following him down the hallway, latching onto his backpack handle, and repeating "Good morning" in a sing-song fashion.

* A follow-up is a sketch of Yamada saying "bye-bye," and Ichikawa spending several panels mustering up the courage to reply. He eventually settles on "See you," and Yamada takes off, satisfied, saying she'll see him tomorrow. She accidentally runs into the door, and he thinks about how tomorrow is Saturday.

* A bonus is the rough draft of Ichikawa and Yamada fighting over the book from the previous Chapter.

**I'm Today's Star** is the ninety-third Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Kyoutarou recaps how on the night of his birthday, Yamada has come over to his house. She apologizes to his mother for showing up so suddenly, but she says it's not a problem. Kyoutarou adds that she wanted to eat some beef, which she protests. Ichikawa's mother frets about how dirty the sink is, and begins cleaning, while Yamada offers to help, but she is told to sit down and relax. She sits down on the couch next to his father, but they awkwardly have nothing to say to each other, and she becomes determined to help clean. Kyoutarou asks if she called home to let them know she's late, and she quickly dials up her mother to explain. Sanae clarifies that it's a friend's birthday, and when Kana comes downstairs talking, she believes it must be a girl. She tells her to have fun, and Yamada then addresses Kana's new, stylish rocker getup, which she refers to as her "party style."

At the table, everyone is ready to eat while Kyoutarou, not too pleased, has on a pair of novelty party glasses and a sash labeled "Today's Star." His sister begs him to smile for a picture while he refers to this scenario as "torture." Yamada begins to address him as he takes off the getup, but Kana tells her to eat up, to which she says she just wants a little because of her "small appetite," which Ichikawa thinks of as an outrageous lie. Their mother comments on how thin Yamada is, saying it almost worries her, to which Kana says she's like a model, and Yamada affirms that she is one. The Ichikawa women ask several questions, while Kana panics about her fashion choice. The mother brings up how Kana got him a present, and when Ichikawa gets it, it is an anime girl figure from a game he likes, which embarrasses him in front of Yamada, while Kana comments on how bishoujo figures are always like that. After the meal, Ichikawa's mother brings out a cake and tells her son to make a wish. He wishes for good health, to which Kana snarkily asks if he's an old man. He blows out the candles, but leaves them all in total darkness, so Kana goes fumbling for the lights. Yamada leans close to him and whispers "Happy Birthday, Kyou," which is powerful enough to send him to the floor just as his sister hits the lights. She nervously asks if they're in the middle of a murder mystery, while Yamada buries her hands in her face, embarrassed.

Later, Kana is trying on various outfits, while Yamada compliments each one with "cute." Kana accuses her of being the type to call anything cute, while Kyoutarou watches their antics, feeling as though they're already friends. Ichikawa's mother asks Yamada if she's fine with time, since it's already 9:30PM, while a drunken Kana mentions that she should stay over the night, since her friends Momo and Hina had stayed over previously. Yamada agrees, on the condition that it's not any trouble, leaving both of the Ichikawa children shocked.

## Trivia

This Chapter is the first mention of Momo, Kana's friend who won't appear properly until Chapter 119.
Chapter 9: I Hid Her

**I Hid Her** is the 9th chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Ichikawa bears witness to Chi giving Yamada a piggyback ride in the halls of the school, while Moe and Serina are offering emotional support. She sets her down in front of the water fountains, and Yamada offers to trade positions with Chi, but she refuses on account of it being too embarrassing.

Back in the library, Yamada gets a call on her cellphone from Moe, warning her that Chi is on her way. She hides unconvincingly underneath the table, and tells Ichikawa to sit on the nearby chair to distract her, which he does regretfully. Chi enters the room and begins grilling him for information about Yamada's whereabouts, while he tries to keep his composure at Yamada being just below him beneath the table. Chi quickly figures out Yamada's hiding spot, but rather than call her out, she takes a seat at the table with Ichikawa. Unsure how to react, Ichikawa offers her some of Yamada's chips, but Chi turns them down on account of her food allergies. She then tells a story about how she went to Yamada's house and found her eating snacks in the hallway, so as to not seem rude for partaking in something that Chi could not. She then begins listing off all of her positive traits, which Ichikawa meekly agrees with. He reacts with shock as Yamada puts her hand on his thigh as she crawls out from under the desk, and Chi mocks her for only appearing only when praised. Yamada asks if all of that praise was from Chi's true feelings, which she denies, but when Yamada offers a piggyback ride again, Chi graciously accepts away from the prying eyes of the public. Ichikawa is left alone; exhausted, overstimulated, and wishing to go to the bathroom.

* A bonus page is a skit involving Chi understanding Yamada even when a sucker is in her mouth. Moe is shocked and they turn it into a game. Yamada tries to cheat by saying nonsense, but Chi still figures it out.

Extra 27.1

**Extra 27.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* The students are putting away gym equipment after class, and Ichikawa is struggling to move a balance beam. Yamada hops on, and invites him to do the same, saying that if he can beat her in a game of sumo, that she'll help him move it. The two go through the motions of a sumo fight, clapping hands, and leaving him uncomfortable, but he knows a secret technique, to thrust from below, as a "surefire" method of victory. He seems to be gaining ground, but accidentally clasps onto her hands, a penalty. She says a second penalty disqualifies him, and he prepares to sumo again. She simply lowers her hands to her sides, however, as he moves his hands up and down, trying to coerce her into defending. At the prospect of simply pushing against her chest and winning, he concedes, but Maeda steps in and yells at them for goofing off, so she helps him move the balancing bar anyway.

* A bonus color page is Yamada lying on a gym mat.

## Summary

* While leaving the school for the day, Ichikawa looks up at the dark sky, when a sudden peal of thunder catches him off-guard and causes him to flinch. He notices Yamada smiling next to him, and tries to mutter out an excuse for his unsightly reaction. Another thundercrash happens, this time scaring Hara as she walks next to Kanzaki, causing her to grab onto him. Yamada then goes over how fearless she is, unafraid of lightning, eating strange foods, roller coasters, and haunted houses. She asks if she's not traditionally girly in that respect, but he says it's good that she has fun. She tries to ask him to join her at an amusement park sometime, but another strike interrupts her line. He considers if his line about having fun may have been dismissive, but she seems not to notice, and he's relieved she's so dense.

* Ichikawa and Yamada are walking home following the events of Extra 34.1. He timidly offers to allow her to ride with him on his bike. She accepts happily, but then quickly hops off, saying they should "take their time." Suddenly a downpour occurs, leaving them drenched.

Chapter 74: Yamada Is Telling Me

**Yamada Is Telling Me** is the seventy-fourth Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Ichikawa meets Yamada outside his house's front gate at 7:26PM. She says that she changed up her routine for Wantarou's evening walk, and realized how close she was to his house, so decided to drop by. They decide to go for a walk, and she offers for him to hold the leash. With her help, he manages to keep the energetic dog under control. They go to a vending machine and Yamada decides to play a game, pressing the button for the drink she wants (cocoa) and a drink she hates (black coffee) at the same time. She gets the black coffee, and so offers it to Ichikawa, which he thanks her for.

They find a bench to sit at, and she tells a story about Chi and some ants, but Ichikawa interrupts her, saying that she's been acting strange all day. She counters saying she's always strange, and he agrees, but she acts shocked that he agreed. He counters by saying she said it herself, and she says that Chi is usually the one who says that, but she isn't here. He asks if she's cold, and she says she's fine, and thanks him for the chocolate from earlier, which he tries to reply to, but stumbles over. They talk about the weather some more, and then she asks if he got any chocolate today, and he considers what she gave him, and his family, but answers "no," and instead asks if she gave any chocolate, wondering if that's a safe question. She also says "no," clarifying that she gave no friend chocolate, and he adds that he agrees with Adachi's opinion that they should do away with friend chocolate, since it just causes misunderstandings and makes men sad, while awkwardly sipping at his drink. She asks if the coffee is too bitter, and he confesses that when he told her he was bad with sweets, that it was a lie. Seeing her chance, she rummages through her bag and offers the cupcake, and he questions the kanji as she breaks it in half, offering him one of the sides. He thanks her, and she says it's okay, turning to him, and adding that it's fine if he misunderstands. They share a few tense seconds in silence, and she begins getting frustrated and tearing up, saying that in the end she couldn't get any of it right. He takes a bite of the cupcake and says it's good, trying to make her feel better, but she asks for a hug instead by opening her arms, which he gives. They walk back to her apartment and he ruminates over his half-cupcake, realizing that she's trying to tell him something.

Bonus artworks include Yamada and Ichikawa in makeshift bunny outfits made out of jean-like materials, a variety of sample artworks, Yamada holding a longcat version of Ichikawa, and an advertisement for Volume 5's physical release.
Chapter 29: My Border For "Like"

**My Border For "Like"** is the twenty-ninth Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Ichikawa is in his room, reading *Your Color's Octave*, and imagining how Yamada looks when she reads. He imagines her in different positions reading, and mimics them, and when he holds the book above his head, facing the sky, crumbs fall out onto his face, and he gets his answer.

At school the next day, Yamada runs up to him as he's washing his hands, asking if he's read any. He says he could not, disappointing her, and he tells himself that he couldn't concentrate. She warns him that if he doesn't read fast, he's going to get spoiled, and he reminds her that that already happened. Adachi, noticing their exchange, follows him down the stairs where he is reading a book. He suddenly asks why Yamada and him are able to talk as if it's nothing, and Ichikawa tries to deflect, saying that it's normal to talk to your classmates. Adachi asks if he knows whether or not Yamada has someone she likes, and if he might know because they're closer. They have a back-and-forth in which Adachi claims he likes her, even going so far as to say he can no longer masturbate to her, which Ichikawa would rather have not heard. He clarifies that "they" say that you can't do that if you're truly in love with someone, which fills Ichikawa's heart with doubt about his own feelings. When Ichikawa asks about what he likes about her, though, he just continues listing physical attributes, making him angry, so he leaves.

When he makes it back into the classroom, Yamada is sitting on his desk, chatting with her friends. He walks up to his desk and pulls back the chair to sit, but decides against talking to her, because it will bring attention to their relationship again. As he glances at her legs, Adachi gives him a wink with accompanying hand gesture, and Ichikawa tells him off in his head.

* A bonus page is Yamada doing a peace sign in a promotion for a webtoon contest BokuYaba was in. Ichikawa is in the background looking through the nominated works.

## Trivia

Ichikawa's book seems to disappear in the final page from when he sits down to when he pays attention to Yamada.
Extra 74.1

**Extra 74.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

A teacher stops Yamada in the hallway while she is talking with her friends, and asks if she is wearing makeup. The teacher asks if she really doesn't, and Moe makes fun of Yamada for having a face that looks done-up without having to do anything. She gets angry and insists that she isn't wearing any. Later, in the library, Yamada is telling the story of what just happened to Ichikawa, and then asks him if he thinks she's wearing any. He reminds her that he does have a sister, and then begins looking her over. He requests that she close her eyes, and she becomes startled, asking him to wait, then pulling out a stick of lipstick and applying it. He notes that this counts as makeup.
Extra 25.1

**Extra 25.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Ichikawa enters the library, wearing a black medical mask. He compares this, along with his usual black school outfit, to a black armor. Yamada is enamored by his appearance, and asks if he wants a paperclip to stop the mask from pulling on his ears. He initially refuses, not wanting to ruin his "armor from ancient times" image, so she just forcefully wraps her arms around his head and does it herself. Once she is done, he pulls the mask up as high on his face as he can, to hide his blushing. He says there is a lot of useful information on the internet, trying to distract her with conversation.

* The next page is Yamada putting on her cardigan.

* Another page is Yamada stretching, and commenting on how hot it is.

* Ichikawa searches the library for Yamada, and notices her hiding behind the bookshelf, his usual spot. He plans to ignore her antics, but she pushes a book out from the shelf, hitting him in the head. He angrily replaces the book, and searches for her, but doesn't see her behind the shelf. Another book then hits him in the leg, as Yamada is seen crouching down, pushing another onto his leg. Seeking vengeance, he plans to also push a book onto her, since he knows she is crouching, but as he pushes a book from above, she stands up, and the book bounces off of her chest. He attempts several times, finding resistance, until the book finally falls to the ground. Yamada, flustered, walks around the bookshelf, declaring herself done with the game.

* Bonus artworks include Yamada in sportswear, Yamada painting, and Yamada pulling up her hair.

## Trivia

This is one of the Extras that appear to have happened after Chapter 30, based off of the placement of the homework hiding her snacks.
Chapter 40: I Became A Training Partner

**I Became A Training Partne**r is the fortieth Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Ichikawa is walking into class, and notices that there seems to be a lot of excitement buzzing around. He listens in on Adachi as he works his way to his desk, and learns that Yamada is going to be in a movie. Suddenly interested, he sits down and focuses his hearing in the direction of the girls. He expects the movie to be a small art-house deal, but instantly recognizes the names of the lead actor, Suga Naoki, and the director, Fukuda Kenichi, concluding it must be a pretty big deal. When he looks at Yamada, though, she doesn't seem particularly excited, though, and he wonders why, thinking she may be concerned that she'll be alienated if she makes it too big.

Later the two are sitting together in the library, and she asks him if he likes movies. He brings up her debut, and she is excited to talk about it, though he teases her by asking if she's playing a tree. She explains she's playing the high-school daughter of the detective who is hunting down the main character. He thinks that she looks way happier than she did before, and that maybe the fact that nobody was paying attention to her role is what made her upset. She brings up that she has dialogue, and recites her catchphrase, "The Hell? Gross," which causes Ichikawa to shudder. She says that kind of dialogue is new to her, and she'll need to practice. She attempts it a few times, with his recommendations, but he gets nervous as more people enter the room and they start to stare.

The scene transitions to a storage closet, with the two hiding inside. He complains about the cramped quarters, uncomfortable being that close to her, but he begins asking questions about the movie to keep the conversation going. She says that they are filming now, and it will likely be out the year after next, in the Springtime. He considers if they'll still have a relationship like they do now, and she asks if he'll see it. He says that he'll try his best to. She gets up to leave, and he asks about the line practice, but she says she can no longer say it.

The next day, Yamada offers Moe a card with the name "Suga Naoki" written messily on it. Moe asks what it is, and Yamada replies that it's his autograph. Moe instantly recognizes her messy handwriting, and smacks her with the autograph.

A bonus page is a rough draft of Yamada appearing before Ichikawa at the school gate.

## Trivia

The subtext behind Yamada no longer being able to call Ichikawa "gross" is that she can't think of him like that after he agrees to see the movie.
