there's this artist on twitter @/suuso_mii who draws them...
i'm larping cause i haven't watched/read the tngw spinoff. but damn i really like kurosaki
i'm picky with live action adaptations of anime because my favorite guy must be cute, and i won't watch it otherwise. some talk about my favorite guys in live action media below!!
i liked death note drama because higuchi was cute. i could forgive cutting his screentime in exchange for making him cute but then again... why get a cute actor and put him in less scenes?? nontheless, the drama was good simply for the reason that higuchi was there. and was cute. ok i'll talk more cause... i love his hairstyle. it's different from the manga but still so higuchi. the faux hawk is such a cool look for him.
i also watched the yowamushi pedal drama (in japanese without subtitles...) because the actor who played midousuji was REALLY cute. but there was a different actor in the stage play so i was fine not watching it.
i've seen kakegurui drama just for manyuda cause i was on kakegurui streak. he's pretty in the manga and his actor was also pretty and the drama was so cool. i love his gamble vs yumeko.
i've watched ajin movie out of curiosity. i've seen some comments about the innacurate casting and well. the characters did look different. i liked tanaka well enough, though i'd prefer if he looked closer to manga. i actually really liked takahashi and gen (and okuyama). sato looked good, but yeah, he should've been older. i think i didn't even watch the whole movie, but i liked the scene with the trio (tanaka, takahashi n gen) shooting the building. it was cool. (i like takahashi the best i think. gen could've been cuter like in the manga XD the long hair is his moe trait)
something i haven't watched yet - sakamoto days live action. i've seen the actor for kashima and he's really pretty. so i might watch it, even though he's a minor character...
and now for blue lock... there's been idk how many stage plays now and well idk if they're even watchable outside japan. i really liked barou's first actor, he was so cutes... the second one is ok but less cute. he looks cute in some screenshots but i miss the first one... and there's the live action movie coming out - and this is just my taste but the guy is not cute at all... maybe he'll look better in action but the promo photos don't do him justice. i'm kinda feeling like not watching it. (attaching pic of my fav stage play barou, yuki izawa)
also the reason why i haven't watched akagi live action... i can't handle washizu without long hair and with a beard... that's not my pookie. i guess it's hard to make a real life old man as cutes as washizu.
i've been planning to watch tokyo revengers drama because mikey and draken both look good. but i wasn't hyped enough about tkrv to look for it... maybe one day...
Namikawa Reiji receives his first task as the Yotsuba Group's new Vice President of Sales: reform a wayward colleague.
(namiguchi if you squint. 3.5k words, content warning for alcohol consumption. crossposted on ao3.)
“One more toast to your new position.”
Reiji forces a smile, tighter now than it was the last time his father said the exact same thing while pouring them both another glass of champagne. Even he can only stand so many heaps of praise and congratulations—especially after nearly half a dozen drinks.
If it were up to him, he would have stopped after one, but he can’t say no to his poor, hardworking father. Certainly not when they’re out at this sumptuous little lounge at the top of the Imperial Hotel, the last of whose patrons haven’t left yet even at this late hour. Far be it for him to reject a suggestion from old Kenichi in front of so many other people, no matter how uncomfortably disoriented he’s felt for the past hour or so. Reiji clinks his glass politely against his father’s and takes another sip of champagne.
Namikawa Kenichi is remarkably slim for his age, with hardly a wrinkle on his pale face and tasteful threads of silver through his slicked-back hair. Reiji has seen him infrequently ever since he returned from America, and he wonders for half a second if the furrow in his father’s brow is a sign of some newfound sorrow, the kind of which he always seemed to have so few. That notion quickly disappears at his father’s next few words.
“I hate to impose on you in this time of celebration, but I’m going to ask a favor of you.”
Even to Reiji’s tipsy ears, it sounds rehearsed. So this is why his father insisted on buying so much champagne for the two of them.
“What is it?” he asks.
His father is quiet for a moment, lips pursed, then finally says, “Do you remember Higuchi Kyosuke?”
Reiji strains to put a face to the name. Higuchi… Yes, it must be Higuchi Jiro’s son, that pimple-faced upperclassman who he’d met a few times back in high school, when his father used to bring him along to company events. What had Higuchi Kyosuke been like? Sullen is the first word that comes to mind. They had spoken once or twice, and Higuchi always seemed taciturn and mildly petulant, like he wished he were anywhere else and didn’t care who knew it. What exactly they had spoken of, Reiji can’t remember.
“Higuchi Jiro’s son?” he answers slowly. “Vaguely, yes. Why?”
“Ah, it’s a delicate situation…” His father smiles uncomfortably. “The problem is… I’ll put it this way. Jiro is one of Yotsuba’s best executives, so of course everyone was pleased when Kyosuke announced his intention to work for the company, and again when he was promoted to Vice President of Development. He’s a good worker, but he’s had some growing pains. It’s nothing serious—some issues with delegation, some hostile interactions. We hoped it was just a matter of adjusting to new leadership, but it’s been almost a month now. Jiro is a good friend of mine, and I owe a lot to him. It’s because of him that I started working for Yotsuba in the first place… but you’ve heard that story, and I won’t bore you with this old man’s sentimentality. My point is that our family owes the Higuchis a good deal, and I was hoping we could return the favor.”
“And you’d like my help?”
Kenichi nods. “If you’re willing. You did excellent work in the American branch, and your leadership and management professors all spoke very highly of you. And, of course, you’ve always had a talent for these things, even when you were young—I know that better than anyone. So I’d appreciate it if you could… give him some advice.”
“You want me to mentor him?” Reiji asks, raising his eyebrows. “As a new hire, freshly back from abroad, multiple years his junior?”
“You’re only two years younger than him, Reiji,” his father corrects, a brief touch of humor touching his features. “In any case, I wouldn’t call it mentoring. Befriend him. It could be that all he needs is someone to lend an ear.”
It occurs to Reiji that he hasn’t even stepped foot in the office yet, and he’s already been given an assignment. He finds, though, that he doesn’t mind; his father hardly ever asks him for favors, and besides, if he can help the company by nudging an old acquaintance in the right direction, then why shouldn’t he?
“Then I’ll invite him for drinks,” he agrees. “I assume we’ll meet soon.”
“I suggest you seek him out as soon as you start. It would be to your advantage if your friendship can cause a change in him.” Kenichi pauses. “It’s always been the president’s preference to put younger men in executive roles—fresher eyes, innovative minds. That’s never sat well with certain members of the board, and if this turns into a larger issue… Reiji, you’re the youngest person we’ve ever hired for an executive position. You know that. What you might not know is how much the decision tested the board’s patience. I have complete confidence in you, but I wouldn’t want to see your prospects hurt by something that isn’t your fault.”
So in order to keep me uninvolved, you’ve decided to involve me? Reiji thinks to himself. But instead of saying it aloud, he just smiles.
“There’s no need to worry about me,” he says. “I’m confident that Kyosuke can reorient himself with my help.”
And the board will see his worth soon, either way.
-
As it turns out, the Development Department is directly below the Sales Department, so paying Kyosuke a visit is just a matter of finding the time to slip out of his office. Namikawa manages it just before lunch, and, as it turns out, he catches his charge in the hallway just outside the development office.
Enough has stayed the same about Higuchi for Namikawa to recognize him after all these years: the same hooked nose, the same hooded eyes, the same thin eyebrows, the same wide mouth set into a scowl. He’s taller than before but still shorter than Namikawa, especially with his shoulders hunched like that, and he’s foregone one ridiculous hairstyle for another—what used to be an embarrassing half-attempt at a pompadour is now more reminiscent of a hedgehog. It’s the haircut, really, that sets Namikawa’s new first impression of Higuchi, more than even the scowl or the hunched shoulders. Trying to be trendy, but not socially aware enough to succeed. Posturing. Immature.
Namikawa’s face shows not a single centimeter of those reservations as he stops in his tracks and bows in Higuchi’s direction. “Higuchi Kyosuke, yes?”
Higuchi, who’s still a couple meters away, slows to a halt and narrows his eyes. “That’s right. Have we met?”
“We have, but it’s been several years. I didn’t think you would recognize me.” Namikawa straightens back up and fixes Higuchi in his sights. “I’m Namikawa Reiji, the new Vice President of Sales. We met briefly in high school. It’s my first day, so I was hoping to reintroduce myself to you.”
Higuchi’s eyes widen slightly in surprise. “Oh, right, Namikawa. I remember you. You… Uh, you’ve changed your hair.”
What an odd thing to say.
“So have you,” Namikawa comments, almost off-balance. It doesn’t last. “You must be busy, so I won’t take too much of your time. Would you like to get coffee sometime?”
Higuchi blinks, a touch of color creeping into his cheeks. After an awkward half-second, his mouth widens into a toothy smirk. “I’ll do you one better. Come get a drink with me Friday night.”
How strange it is to be working in Japan after all these years; Namikawa’s colleagues in America would never have asked him out for drinks. If only the prospect of swallowing beer and sake with Higuchi were appealing in the slightest.
“That would be wonderful, thank you.”
-
Friday comes all too quickly, and, since Higuchi is his senior, Namikawa unfortunately decides it’s best to let him choose where they go.
“Most people can’t get in here,” Higuchi brags as they walk past the bouncer. “Luckily, I happen to know a guy.”
Namikawa wonders if that’s supposed to impress him as he glances around at the tacky gold and black decor. Then again, he thinks to himself, Higuchi raises a good point: Namikawa has been out of the country for so long that he doesn’t know many people in Tokyo, and he would hate to invoke his father’s name to get in somewhere. Not that he’s much of a drinker, anyway, and if he was, this bar wouldn’t be his first choice.
When Namikawa doesn’t reply, Higuchi adds, “Actually, it’s not a matter of luck, at least not for me. Have you been here before?”
“No, I haven’t,” Namikawa responds absently. “I’ve hardly been to Tokyo since I graduated high school.”
“Oh, that’s right, you’ve been abroad,” Higuchi laughs, sliding into a seat at the bar. “Find anything worth doing in America?”
Namikawa follows. “Of course. Harvard was an excellent experience.”
“What made you want to go to university in America, anyway? Nowhere good enough for you here in Japan?”
Higuchi’s tone is so overly casual that Namikawa can’t help but close his eyes, a thin smile creeping across his face. Maybe it was intended as a joke, but he’s sure there’s a note of resentment behind it. He wants to bite back that it’s Harvard, Higuchi, what do you think made me want to go, but he refrains.
“The faculty,” he answers simply, opening his eyes and glancing sideways at his companion. “I was thinking ahead to my master’s degree, and it so happened that Harvard’s business professors annually put out a number of excellent research papers and other projects. There’s also the name recognition, of course.”
Higuchi looks bored until the moment their eyes meet, at which point an odd look comes across his face: his mouth opens halfway as if he’s about to speak and then simply stays there, his eyebrows furrow just slightly, and a red-pink color creeps across his cheeks and the tip of his nose. For several seconds, they just look at each other, and Namikawa realizes that there’s something familiar in Higuchi’s expression, something he would normally have recognized immediately. No, surely not.
Fortunately, the bartender emerges before the silence can continue. Namikawa is quick to turn his head and order a glass of pinot noir, and as the bartender moves on to Higuchi, he reminds himself why he’s here.
“Where did you go to college, Higuchi?” he asks once the bartender steps away.
“Wasegi,” answers Higuchi, watching the bartender instead of Namikawa.
“In Shinjuku? I’ve been to the garden there.”
“Yeah, yeah, it’s pretty nice… I didn’t spend much time on campus, though. Don’t get me wrong, Wasegi is great, but I was trying to get in and out of there, you know?” Higuchi laughs just a little too loudly. “Some people say university was the best time of their lives, and I say they’re crazy. And pathetic—imagine spending your entire life sad that you’re not sitting in a lecture hall, listening to hours and hours of some old codger droning on about constitutional law. It’s backwards, if you ask me.”
Namikawa’s mouth twists. “You didn’t enjoy being a student, from the sound of it.”
“That’s not what I mean,” Higuchi says immediately. “And I’ll have you know that I was a model student. But I’ve always had issues with the way classes are usually taught. You can force a kid to memorize a bunch of historical facts, but that won’t help them find a job or get married or… or anything else that actually matters in life.”
“And I take it you didn’t appreciate your professors telling you what to do, either.”
“More like I didn’t appreciate them telling me how to think.”
Namikawa wants to tell Higuchi that the only people who find their independent thought threatened by their professors have very little to begin with. He reminds himself again why he’s here, and instead he says, “I hope you haven’t encountered much of that at Yotsuba.”
“At Yotsuba? Huh. I wouldn’t want to scare the new hire.”
The bartender reappears with their drinks. Namikawa thanks him politely and watches Higuchi swirl the glass in his bony hands before taking a large sip.
“You’re not going to scare me,” he replies with a small smile, leaving his own drink to sit on the bar. “Surely it can’t be so bad.”
“There’s worse, that’s for sure.” Higuchi takes another sip and sets his glass down. As he does, his eyes slide over to Namikawa’s, and his face immediately draws together into a look of concern. “We got the same drink, didn’t we?”
Namikawa glances over. “It seems we did.”
Higuchi squints, then slowly relaxes his face. “Ha… I didn’t realize. If I had, I… Oh, whatever.”
“We must have similar taste,” Namikawa comments. He wonders to himself why Higuchi even cares, but the bemusement doesn’t reach his voice.
“Right…” Higuchi frowns, and a distracted, faraway look comes over him. He takes another drink, then blinks a few times. “Anyway, what were we talking about? Yotsuba?”
“Yes, Yotsuba. Ever since I was young, I’ve had the impression that the culture there is quite individualistic, as far as these things go. That’s what everyone says, and Mr. Yotsuba himself seems to encourage independence.”
“You know him?”
“Not very well. My father introduced us years ago, but he left an impression.” Namikawa thinks back to Yotsuba Dainosuke as he was then—wide and on the taller side, with thin, pale hair and fiery eyes for a man of his age. Not much has changed, although he’s gotten much balder.
“Your father told me you want to go into sales,” he’d said with an electric smile. “With a pretty face like that, you’ll catch anyone’s attention. Ha! But looks aren’t everything. Give me your elevator pitch, Namikawa.”
After all these years, Yotsuba had remembered Namikawa’s response well enough to mention it at his first interview. Maybe he’d mentioned it to put him at ease, but in actuality, it had left Namikawa feeling embarrassed for the first time since he was an undergraduate. Not that he’d let it show.
“Mr. Yotsuba isn’t so bad,” Higuchi admits, swirling his glass again. “But he isn’t willful enough. He does whatever the board tells him to, you know.”
“The board?”
“Yeah, the Board of Directors. Bunch of old hasbeens who can’t stand to let anyone else make decisions. You’ll see what I mean soon enough.”
Issues with authority are such ugly traits for an executive. Oh, the things Namikawa would say if only his poor father hadn’t asked him a favor, or if only he’d been at Yotsuba for longer. .
“Thanks for the warning,” he says instead. “I assume you’re speaking from experience?”
“Oh, not really…”
“Any company that wants to stay on the cutting-edge has to trust fresh talent. I thought the Yotsuba Group understood that.”
“So did I, but not the board.” Higuchi stops, finishing off his glass of wine and gesturing to the bartender for another. He crosses his arms, and his face forms something like a pout. “They don’t like the way I run things, apparently.”
Good—now they’re getting somewhere. “Why’s that?”
“Oh, they think I’m too demanding or some bullshit. I bet one of my subordinates went complaining to them. In fact, I have a few ideas who it could be…”
The fact that Higuchi has a few ideas about who it might be is not a good sign. “Who?”
With an exasperated sneer, Higuchi launches into a list of his most rebellious subordinates, gesturing with his hands all the while and drinking down his second glass of wine at an alarming speed. Before long, a third is en route, and Namikawa’s glass gradually slips from full to half-full. He tries to pay attention to what his new colleague is saying, which normally wouldn’t be difficult, but something—he isn’t sure what—has his mind wandering. For what it’s worth, he doesn’t particularly care which one of Higuchi’s subordinates is responsible for his little problem; for it to have progressed this far, the problem must be more than one disgruntled subordinate, anyway.
If this experience contains even the slightest bit of worth, that’s because it holds some instructive potential. When Namikawa comes across his first conflict in the Sales Department, he’ll bring Higuchi’s face to his mind and remind himself how not to handle it. The way his new colleague talks about the situation rouses all sorts of unpleasant things to mind: targeted derision in front of the entire department, vague yet accusatory emails sent out to (again) the entire department, increasingly contradictory directives. And Higuchi has yet to mention what exactly he does other than order his subordinates around. Namikawa is starting to suspect there’s little else for him to mention.
But, somehow, listening to Higuchi talk isn’t completely unpleasant. Maybe it’s because he’s only half-listening anyway. His animated facial expressions and gestures—more animated as he drinks—are almost entertaining. The occasional slip into vulgarity as he rambles on is almost amusing. His sharp white teeth, which flash in the light every time he opens his mouth too wide, are almost charming. Almost. Just close enough to be all the more annoying.
Namikawa reminds himself that someone like Higuchi has no right to annoy him—no, he has no right to allow someone like Higuchi to annoy him.
Fortunately, Higuchi pauses in between thoughts, just long enough for Namikawa to seize the opportunity. Folding his hands over the bartop, he comments, “It sounds like there’s a widespread issue in your department.”
“Oh, it sounds like it to you, does it?” Higuchi barks out a laugh. “You’re telling me. I don’t know how I ended up with these guys.”
Namikawa allows himself a small, unamused smile. He closes his eyes briefly and replies, “That’s not quite what I meant. Work culture is almost always top-down.”
When he opens his eyes again, Higuchi is staring at him, his already-red face somehow turning brighter. “What, you think it’s my fault those idiots don’t know how to do their jobs?”
“Well, do you know how to do their jobs?” Namikawa asks evenly. “You could try to lead from the frontlines more often, instead of doling out criticism while your people do all the work.”
He hadn’t meant to sound so blunt, and, for what it’s worth, his tone isn’t unkind. But that doesn’t seem to matter, because he’s clearly hit a nerve. Higuchi sputters for a moment, then makes a face that resembles a snarl. “What do you know, Namikawa? You haven’t worked a single month in the office yet. I’ll have you know that I do plenty of work. In fact, I’d like to see you take a walk in my shoes! You wouldn’t last a week.”
Namikawa finds himself so oddly, intently focused on that nasty, animal-like expression Higuchi is making that it’s difficult to pay much mind to what he’s actually saying. After a moment, he replies in the same tone, “I’m not trying to tell you your position isn’t difficult. It’s a simple observation: When a department has this many malcontents, it’s not just a case of a few bad apples. It must be serious, especially if members of the board are intervening. If you don’t want to be on the hook, you ought to make a few changes.”
“Thanks,” Higuchi sneers, “but I don’t need advice from the new hire. You might have been hot shit in the American branch, but you’re still my junior.”
“There’s no need to be rude, Higuchi. I was only trying to help.”
“Not rude, just honest.” Higuchi rests his arms on the bar and hunches over himself, staring down at his drink in what Namikawa can only assume is a pointed refusal to meet his eyes. Or maybe he’s just so drunk and embarrassed that he doesn’t realize how he’s acting.
Well, Namikawa isn’t going to grace him with a response. Higuchi can stew in his own feelings until he can’t stand the silence anymore and tries to walk back his outburst. Suddenly, though, he turns his head and looks at Namikawa’s glass for a long moment.
“You’ve barely had anything to drink,” he comments, looking up at Namikawa. The beginnings of a devious smile are spreading across his face.
“I never drink much.”
Higuchi clicks his tongue. “What a shame. All this time, I’ve been wondering why this isn’t any fun… I might as well be drinking alone.”
Namikawa closes his eyes. “I hate to disappoint you.”
“We can always try again.” When Namikawa opens his eyes, Higuchi is grinning. “If you finish your glass next Friday, maybe I’ll listen to your advice.”
And so went the first of many Friday meetings, and the first of many unheeded suggestions.
sharing my higuchi headcanons!! the issue is that i don't have many headcanons and some of them are literally: this is my trait and i want him to be more like me.
-he likes tech and gadgets (in line with his job at technology development department) but he's not THAT tech savy. maybe a bit more than the average person? he's no engineer. i like the idea of him buying gadgets he doesn't need and being like look at this thing, it's so cool right? (kinda like my dad lol)
-he keeps brief contact with his parents. when he was a kid they were very permissive, he was never really punished for anything and he was spoiled. i think his father is stoic and cold, never praised him and there was always a lot of comparison to others. always lowkey disappointed that kyosuke isn't more exceptional. the relationship got even more strained after the demotion. i don't have much thoughts about his mom, but he was definitely closer to her.
-him being a five dan in kendo is canon but for my thoughts about it: i don't think he practices it anymore. probably stopped once he started working? (i do need to learn more about kendo to form more opinions)
-he likes wearing brand clothes. big brand names and stuff. to the point it might be tacky? he doesn't mind tacky, he needs to make an impression, doesn't matter what kind.
-he likes flaunting his money and he's not stingy at all. he'll spend a lot on a woman he likes. doesn't care about the concept of "gold diggers" because he's aware money and status is his appeal.
-this one i keep going back and forth: if he has passive suicidal ideation. that's what i gravitate to when i try to write him pre-death note, but i actually don't know if it truly fits him. he sometimes seems not to have much thoughts so maybe he's not that bothered by his life. (but on the other hand, what person who likes their life would use a death note?! then again, as we established he doesn't think that much...)
-he has a tendency for vasovagal syncope (or more precisely, presyncope). his main triggers are: small injuries that bleed (like cutting his finger) and getting blood drawn. he doesn't actually faint but gets really sick for a minute or two. has to sit down or he'll actually pass out. embarrassing in public. probably HAS fainted in the past. (i don't care if it's unrealistic or doesn't fit him i think it's cute.... i also have experience with this so i can imagine exactly how it feels)
-related to the last one i also think he's squeamish around blood. prefers to look away.
-low pain tolerance.
-the people he talks the most at work (from the yotsuba 8) are mido and takahashi. he sees hanging out with takahashi as slumming it, but they are similar levels of sleazy. oh and i think higuchi might be less mean in private, cause he doesn't have to impress anyone haha.
-this is a small hc for what happens in the plot but i like to imagine he had a concussion from the car crash :3 he wasn't wearing a seatbelt and he did hit his head so it's likely.
Kazuya again bc I love him
He's a little bit younger here I guess. Didn't plan to draw him this way but it just happened.
He's not used to smoking yet, but he's trying to look cool anyway. Or something. I don't really know, I just wanted to draw Kazuya.
hello hello there is it guys as i promised, it has the classic tier list ranking system but you guys can add whatever ranks you want!!!!! PLEASE DO REBLOG with your tierlists !!!!! id love to see it!!!! tagging @squarliank @frootyfandomstuff and @amaianita cuz i promised!! HAVE FUN!!!!
all kaiji ships ive seen so far. no ships like kaiji x morita for obvious reasons of it being crossship even though akakai is in there KEK m
i also love this line. it's the cutest thing ever. his face is so cute, i love everything about it. his droopy eyebrows, his sanpaku + tsurime eyes, his roman nose, his wide mouth, his hollow cheeks, his long chin, how expressive he is and all the lines and wrinkles that show up when he makes faces. (pretty obvious i'm obsessed with all his features since i keep drawing him and i really try to capture him well)
i stopped at 8 because that's the limit for a group picture. wanted to do all the villains but i ended up skipping ootsuki sorry... (btw i feel like a kaiji larper cause i watched it so long ago... can someone remind me how they call each other?? the honorifics etc. cause i can set up the nicknames but i don't remember 😭)
i started playing tomodachi life so i'm consumed by it lately!! i made the yotsuba group and i want to post them all together but i'm still wondering how to get the photos from my switch to my computer. would be convenient to use an usb but idk if a regular one will work? or do i need a special one? alternatively i can take photos with my phone but the quality will be worse.... pondering
heyyy i was so happy to see you back!! i want to ask if you have any namihigu headcanons (or for other higuchi ships?) :3
Thanks! I plan to put more Death Note shower thoughts on this blog (I know, contain your excitement).
Anyway, you're in luck because I actually think about Namiguchi a lot. I like the opposites attract sorts of ships. I also just like both the characters. A lot. (Are you shocked that the guy running the Higuchi-themed blog is partial to Higuchi?)
My main thing is that they definitely met in a goth/industrial crossover club. Higuchi I headcanon as a rivethead. I've decided he's really into Slick Idiot and Lords of Acid (a friend of mine introduced me to them). Namikawa is definitely a goth. Like, undoubtedly. He oozes "you can't sit with us" goth elitist attitude. Nothing but contempt for the world and a sense of betterment over "appreciating the classics". He's a trad goth kind of guy: SoM and Christian Death, but I think he'd also like a lot of Japanese bands like Phaidia, Auto-Mod and Kokushoku Elegy. He doesn't like Sadie Sads because they're too weird and he doesn't like 80s Buck-Tick because they're "not goth enough". A bit of a tangent (lol) but basically Namikawa's morbid curiosity ended up in him dating Higuchi,
Along a similar train of thought, they hate each other's music taste. Higuchi thinks Namikawa's music is "pretentious as hell" and Namikawa thinks Higuchi has the music taste of a teenage boy. They frequently argue about music taste and Higuchi laughs at Namikawa for saying every goth band that has a harder sound is probably industrial,
Their relationship isn't 100% healthy. They do fight a lot (usually over nothing). Their arguments are extremely petty, but occasionally Higuchi feels a little sidelined by Namikawa. Namikawa has a habit of treating him like an embarrassment (you know those "I can't take you anywhere!" sorts of people). This obviously, as it would for anyone, makes him feel extremely insecure, which isn't ideal since he already fucking is. Higuchi had major self-esteem issues before their relationship (he has his whole life) and Namikawa only exacerbates it. I will say that I don't think Namikawa does it on purpose, and in a way that makes it worse. He doesn't think about how his nature affects his partner's self esteem because to him, insecurity is entirely foreign. He's never had to worry about looks, intelligence or popularity the way Higuchi obsessively does because he's treated 10x better by literally everyone. Namikawa's behaviour isn't intentionally malicious, but it has a negative effect nonetheless,
Higuchi and Namikawa aren't publicly involved with each other (obviously Japan in 2003 isn't going to be a bastion of LGBT rights, and people don't really talk about relationships anyway) but they do have each other's backs in their own weird ways. Higuchi will talk insane shit about Namikawa both to his face and behind his back, but gets extremely pissed off if anyone else does it. Kind of like how you're allowed to talk shit about your sibling but nobody else has the pass. This massively confuses the other Yotsus and the more astute ones of them (anyone but Takahashi) suspect that they're undoubtedly dating. Namikawa is more subtle. He doesn't necessarily chastise people for saying anything bad about Higuchi, and he's definitely the first to tell Higuchi when he's being an idiot, but he does make sure to change the subject so that the other person can't continue slagging him off.
Namikawa is the one that remembers important dates (and general to-dos). He's the one that drops the "it's our anniversary soon" and Higuchi is the one that grits his teeth and thinks "shit, I completely forgot". Namikawa books their dates because betting on Higuchi remembering to do it will give you a permanent losing streak. One Higuchi headcanon I have is that he has pretty bad ADHD, and was treated like a problem child his whole life, but wasn't taught how to deal with his disorder. This manifests itself as him forgetting to do a lot, alongside general impulsive behaviour. The only time Higuchi will actually organise a date is on a whim, and he'll tell Namikawa last minute (much to his dismay). Just another example of the shitty things they do to each other (they're such a perfect match).
In short, Higuchi and Namikawa deserve each other and nobody else because subjecting a third person to either one of them would be exceedingly cruel and a violation of their peace of mind.
