I guess you've heard of my reputation, I've had my share of foolin' around / But everybody needs stimulation and mine just happens to be all over town (Gigolos Get Lonely Too – The Time).

I have two crackpot conspiracy theories for show-and-tell today, isn’t that fun? Firstly, my Instagram feed has been completely taken over by cat videos, and it's by design too. Do you really think I’m about to scroll past a cute cat and not heart it? But I’ve noticed that even though cats are very popular already, a niche subculture within the “cat community” has also formed over time that I don’t remember being there back in the day. Just what the hell am I talking about? Okay well, whenever people are talking about orange cats, it's always a “they have no brain cells” kind of thing. They're commonly said to be stupid, “orange cat behavior” and all that. I know you’re wondering what the big deal is seeing as it’s all just a bit of fun… well, that’s where the whole “crackpot theory” thing comes in: I've had the stray thought that people fall back on this excessive use of stereotyping for cats as a form of micro-dosing on racism. Yeah I know, I know, that sounds crazy, but by masking what would be seen as offensive for actual people behind a “uwu look at this stupid breed of cat that’s always doing dumb shit,” people are able to have a release for their repressed bigotry that would otherwise manifest in more offensive ways. I’ll move on to my second theory because I can tell I’m losing you! Yeah so, I also have the sinking suspicion that the Goodreads recommendation algorithm is working overtime specifically to move me over the dark side of exclusively reading manga. No more literature for me! Pretty soon I’ll only be able to read something if there’s a pretty picture involved! Hey, maybe I should make one of those “comic books explained YouTube channels where I have an embarrassing amount of Funko Pops decorating the wall behind me where I explain every manga I read in such vague, yet excruciating detail that you'd think I used A.I. to write a summary for me. I mean, I’ve never used A.I. in my life and I never will, so if I do go down the “manga explained” route, you can take solace that even if my writing sucks, then it’s still all me. Sorry, I know I’m a bit all over the place right now, must be my “orange cat brain cell” that’s making it so I can only focus on one thing at a time teehee.

Truly, I really do love Goodreads’ recommendation system because it’s always done me good, showing me banger after banger, and that holds true with Dysfunctional Family Theory by Mayo Tsurukame! This manga isn't just mayo, it has the sauce! Now, the first thing I’ve noticed about this manga is that even though it’s another lovely gay romance with a lovely gay cover, it’s actually not simply another Sasaki and Miyano clone. Can you imagine? I know I’ve said that I would read any gay manga that emulates Sasaki and Miyano (“S&M” for short), and that still holds true, I can’t get enough of the perceived bad boy actually being a big ole softie, but what about a manga where the bad boy is an actual bad boy? Yeah well, that’s what Dysfunctional Family Theory is all about, the slow burn romance between two dudes who aren’t just forced to be in the same proximity with each other, but are so undeniably attracted to each other despite having a visceral hatred for everything the other represents. This manga starts with Sentaro, a guy who ghost writes jingles for children’s cartoons, finding out that his old ex Ririko had recently passed away and claimed that the father of her six year-old daughter, Meguru, is either him or the guy that she had cheated on him with. Enter Touma, a (maybe) gangster who’s, well… he’s an asshole and a jerk and maybe Sentaro’s always been a little bit in love with him despite their messy past. See, Ririko’s will states that not only do Sentaro or Touma have to take care of Meguru, but at the end of three months she gets to choose who she wants as a father. Okay look, you’re probably thinking that the premise is probably overly convoluted and silly, and we're in the same boat here, but sometimes you just have to let yourself be pleasantly surprised by something you’re reading because then you might find a beautiful gem of a story. Let me tell you, I was pretty damn surprised to find a heartwarming story about self-worth and trying to be better for the people you care about. I know that’s not exactly a unique story arc, but hey, when it works, it works!

What Dysfunctional Family Theory has going for it is that it doesn’t mince words about how people would actually treat each other if they’re, you know, losers and forced to be around each other. You know, harsh realities and all that. Due to this narrative honesty, the story never becomes the gimmick that the premise would imply. Touma is an asshole and Sentaro is always admonishing him for being so, and on the other side of things, Sentaro is aimless in life and both Meguru and Touma waste no time calling his ass on it. Normally, don’t really enjoy stories where queer dudes have to raise a kid because it sometimes feels like these stories are written with an overly “heterosexual lens,” for lack of a better term. There’s a sense of conformity in the narrative that makes me somewhat uncomfortable, and this goes doubly so with manga in general, because I’ve noticed the medium loves to have the “precious angelic” child character whose cuteness cleanses the world around them like Final Fantasy: Crystal Chronicles, but that’s simply not the way kids usually act, you know? It’s not like this is a hill I’m particularly dying to die on, but the only kid in recent memory outside of the manga that I’m currently reviewing that reads like a real child is Anya from Spy X Family. And Meguru from this manga must have taken notes, because even though at first glance she seems like she crawled straight out of The Omen with her evil glare and non-emotive face, the only reason she’s like that is because it’s a defense mechanism to shield herself from the world. Because even though Ririko is constantly remembered as a fun person in life, the truth is that she was non-committal and neglectful to the people in her life, especially her daughter. So yeah, what’s cool about Dysfunctional Family Theory is that we get to see a more unique dynamic that’s purposefully uneasy and fraught with conflict, and it’s really interesting to see the subtle shift where the insults thrown around go from pointed barbs transforming into fond admissions. This is a family that constantly roasts each other, but by the end of volume one, you can tell they love each other regardless. This is a manga for the fuck-ups, and it has to be… because how else would it be able to let people know that there’s always more time to be better?

“That’s what dying’s like. People pity you. They try to clean up after you. The living remake you the way they wanted to see you. Whole thing’s disgusting.”

Ein netter, gut gezeichneter Manga über zwei Kerle, die plötzlich Vater sein sollen, und somit zusammenleben müssen.

Der Anfang war ehrlich gesagt ziemlich dumm - und für mich üebrhaupt nicht nachvollziehbar. Aber dann gäbe es die ganze Story nicht. Sentaro und Toma werden zu einer Oma gerufen, die ihnen sagt "Ja vor 7 Jahren hattet ihr Sex mit meienr Tochter, einer von beiden is vermutlich der Vater von meiner Enkelin. Aber keine DNA-Tests." Das ist halt Bullshit - sorry. Um den Vater rauszufinden, macht n DNA-Test, sonst wär ich aufgestanden und gegangen... aber wie gesagt, sonst gäbs die Story nicht, also bitte.
(Wieso die beiden das mitmachen, versteh ich eh nicht, beide haben die Mutter schon Jahrelang nicht mehr gesehen, also ja.. dumm.)

Danach folgt aber ein spaßiger, aber auch hier und da ernster Manga, wie die beiden Kerle, die sich nicht ausstehen können, zusammenleben müssen und gleichzeitig ne 6jährige Tochter haben. Das Mädel ist überraschend spaßig zu lesen, find ich, und der Manga hat gar nicht soviel mit Kindererziehung zu tun, wie ich gedacht hatte, sondern es geht mehr ums zwischenmenschliche, darum wie scheiße die Gesellschaft ist, was man tut, um zu überlebn etc.etc. Es ist für den Titel her überraschend ernst bei einigen Sachen, hätte ich nicht erwartet.

Qué divertido y, a la vez, tenemos una historia más seria y profunda de lo que parece y todo partiendo de una premisa que parece totalmente absurda, pero que logra que dos personas vuelvan a verse y que la vida de una niña solitaria pueda llegar a ser feliz y con una familia de verdad.

what do you mean pick a papa? the other one is a mama!

this is unbelievably engaging! i love the character dynamics so much i can’t stop smiling!! and little meguru reminds me so much of dakota fanning in that uptown girls movie. they got the same energy and haircut?! nonchalant fluffballs!

i was honestly thinking of merely skimming the first few pages before i sleep but i ended up finishing the whole volume!

tell me it did not stop at that scene?! how cruel could you be, sensei? i’m so deprived of boys love these days and the few drops from slow-burn danmeis are really killing me—and you just had to add this one today!! i can’t wait for the sequel!!

p.s. the alternative german cover is everything! i love them fluffballs so much!!

3,5 stars !

I *LOVED* the concept, even though it was a little crazy. Execution-wise however, I am left a little dissatisfied. I think the story was a little rushed. I wish we could have had more time with the characters.

However, I love the art style!! It was really pretty.

Besides, I was pleasantly surprised at how the late mother isn't slutshamed in spite of that CRAZY SET-UP! That was nice.

Also, I did feel like there was great potential for me to love the characters. So it really is maybe the fact that there are only two books? Because of it, we didn't have that many slice-of-life moments to feel the bond between the characters. I think a little more yearning would have also helped greatly.

I wasn't expecting the ending of that volume!! Still, I'm not particularly a fan of that devolpment being linked to alcohol. I kind of wish it had been more emotional or scandalous ahah.

HOWEVER, it was still a super fun read and I had a great time! I went to read the next volume directly after it so it was still perfectly entertaining!!

Pensé que esto sería por sobre todo risas y cozy, y aquí me tienen triste :C es que... es una historia tan linda y a la vez con temas un poco devastadores: soledad, el miedo a perder a alguien, amores pasados, dejar ir sueños o tener miedo a seguirlos, la vida adulta, y tanto más ;-;

Me encantan todos los personajes, sus personalidades por separados y juntos.

En detalles que me encanta ver: la portada del primer volumen tiene a Sentaro de frente, de fondo Touma y Meguru. Y esto ocurre porque el primer vol está enfocado en el POV de Sentaro: su carrera en la música, su relación con Ririko (la madre de Meguru), su pasado con Touma (chismeee), y su papel como "padre sorpresa". Su arc tiene partes que me apretaron el corazón, Sentaro es un personaje bastante complejo y fácil de entender, especialmente lo que es navegar la vida adulta y tus sueños.

Al inicio sentí q era muy forzado eso de no hacerse una prueba de paternidad, pero según investigue en Japón el pedido de un difunto es muy importante tomar en cuenta, entonces saltando nos esto; me parece una lectura bastante ligera y disfrutable.

She was a bright person through and through.


It doesn't happen very often for me, but sometimes I come across a premise I can't keep out of my head. And Dysfunctional Family Theory caught me hook, line, and sinker. So to have to rate this three stars makes me a little sad, since it sounded right up my alley; the distinct queerness and 'dysfunction' of found family, a cute kid, and two guys who definitely couldn't stand each other.

I'd like to say first that the manga's art is very beautiful, especially the color spreads. Tsurukame has an incredibly grasp on color theory and knows exactly what to use to make their saturated art stand out. I also love the sort of fountain-pen style linework. However, the speech bubbles' common lack of a tail made reading a little clunky, sometimes I'd have to pause and parse out who exactly was saying what.

This manga is obviously character-driven, so I completely overlooked the technical inaccuracies of how Ririko's will would even fly in court when it came to guardianship of Meguru. The interactions between Meguru and Sentaro were some my favorite parts of the volume; seeing him act like a dad was genuinely so amusing and made my teeth ache.

Though I think in this case I expected too much out of what is meant to be a short-and-sweet, cute slice of life. I couldn't suspend my disbelief on the development of Sentaro and Touma's relationship, it just felt so sudden and out of nowhere. I can believe that Sentaro had a big fat crush on Touma in the past, but they only met a couple times and to claim that he's "in-love" with him when he barely knows anything about Touma (and neither do we, for the most part) just didn't make any sense to me. Not an insta-love fan, sorry. Worse, Touma hasn't really shown any sort of attraction back, so it's this whiplash between Sentaro supposedly being lovesick and then Touma, who's still in the backburner. The character arcs were neat, but I feel like if this manga was given more time and more chapters there could've been a lot more done and explored. If Ririko and Sentaro had dated longer, if Touma and Sentaro had maybe known each other and been friends for longer, if we were given more time during those three months to develop their relationship more slowly. It comes to the fact that Dysfunctional Family Theory could've benefited from being longer just so that its potential could've been fully realized.

The star of the show for me was definitely the conversations about the dead, their legacy, and how they're meant to be spoken about posthumously. Should we really sanitize their image just to preserve our own feelings? Or is it better to confront the grime head-on and brute force through the hurt that comes from being honest? I was pleasantly surprised, and wish that the story had given more on that and on Ririko as a mother and a person.

Història que s'acaba convertint en BL de dos possibles pares d'una criatura de 6 anys que hauran de conviure amb ella arran de la recent mort de la mare (vividora, despreocupada i que no explica la veritat al testament). Un triangle amorós raríssim, amb gens de comunicació i comportaments egoistes totalment immadurs. Percebo zero química entre els protagonistes i només em lamento per la pobra nena, massa madura per a la seva edat, que no té més remei que conformar-se amb una família desestructurada... En fi, no m'ha agradat gaire ^^'

A few confusing narrative bits aside, this was really cute.

Although...while I'm unfamiliar with Japanese law, I'm pretty sure a woman writing a will and saying "one of you is my daughter's dad, don't take a DNA test though to find out which one, just let her choose" wouldn't hold any water in court. It's not totally explained why Sentaro and Touma would go along with it - particularly since Sentaro had literally only dated the woman for a single week seven years earlier. And Touma, while he was her boyfriend for longer, and far more likely to be the actual father, isn't exactly the most responsible guy.

Plus, would a grandmother really turn her granddaughter over to a couple of good for nothing men? Even if she is regularly staying in touch with Sentaro via video chats while he tries to learn how to cook and care for a 6 year old.

But for some reason they form a weird little household for the three months they're meant to stick together until their maybe-daughter decides which of them she likes the most. Touma, I think, is mostly along for the ride because he has zero doubt that Sentaro is going to "win" (or lose, depending on if they actually want a kid...which neither does). Sentaro is just kind of a pushover.

I went back and forth on being confused about Touma's job...I thought he was yakuza, then a host, then I thought maybe an undercover cop, but looks like he was just yakuza all along. Which is a kind of random complication to throw into the mix. Would the grandma really be okay with that? But maybe she just...didn't care that much about being a parent to a grandchild her own delinquent daughter had pretty much tossed to her.

This leaves Meguru in a pretty rough spot. It's not much surprise that she's a loner at school and doesn't know how to connect with the other kids. It seems like she hasn't gotten a lot of love or attention at home, so she keeps herself pretty closed off and just stays in survival mode. She needs a dad because she's a kid who can't take care of herself. Otherwise she's not all that bothered about who she lives with.

Sentaro and Touma are, to varying degrees, doing their best, and are gradually becoming kinder and more attentive. Their main family-bonding moment so far is trying to encourage Meguru to participate in the relay race at school, even if they're bumblingly bad at both encouragement and the physical act of running.

Beyond fatherhood, there are additional complications to the relationship between the two potential dads. We finally discover through slow flashbacks that while Sentaro had "dated" Meguru's mother for a week, he'd been in love with her coworker, Touma, the entire time. Pointlessly in love because Touma wasn't all that friendly with him and had said some disdainful things about Sentaro's band and his role in it.

So Sentaro gave up on the band - no one else in it was invested in making a career out of it, anyway - and in love, and wound up seven years later in a job that I found kind of confusing. He seems to work for some kind of music agency as a composer, but he also seems to be rejected regularly from competitions and things, so is he actually getting any sort of a regular paycheck from them? Or is all his money coming through the ghostwriting he's doing for a very popular composer?

Frankly, I'm not sure anyone actually knows who writes the jingles for ads or even the opening songs for children's cartoons, so it doesn't seem to me like a particular person's name would hold much sway with the public, eagerly waiting for a commercial to air...plus I don't get how that dude got big name recognition to begin with before his success was riding on Sentaro's ghostwriting.

Weird little plotholes that maybe I'm not fully understanding. But the theme is about Sentaro being willing to finally step out of the shadows and go for what he wants, under his own name, instead of taking the easy, secret path for all these years.

And when he celebrates that decision by getting a little tipsy, he winds up kissing Touma and telling him he'd been in love with him 7 years earlier...so that's going to be a bit of a mess to clean up.
