Not just another NTR. But instead just a bittersweet LOVE triangle.

I generally hate NTR, but probably for a slightly different reason than others. I loved this one, because even though it is technically NTR, but the feelings involved make it more of a love triangle. It doesn't even matter that in the beginning of the manga she already was going out with her boyfriend for 5 years, it can still be love triangle. Even though it is not exactly romantic, it is about doing everything for the loved ones though.

Also I see many people raging after reading this, but I instead find it bittersweet. I kinda can see why they rage, but I think what they don't understand or don't want to understand is virtue of selflessness. Because certain selfless actions hurt person in question, but you know that is what it take to put other people's happiness over your own, even if you do it the wrong way...

More specifically on selflessness, spoiler ahead:
Spoiler (mouse over to view)
Yes she broke up with both of them, but only because she couldn't find a way for everyone to be happy.
She even had an affair because she thought about her best friend happiness, even though that best friend had an affair with her boyfriend.

She does those things one sided, she tries not to show her pain, because she wants to help others, but doesn't want others to be forced to help her. Which results in a lot of contradictions because when both want the other to be happy but can't think of any other way then actually breaking up.

Well sure threesome part was weird in some way, but hey I actually liked this unorthodox approach to relationship. And it is truly about both guys trying their best to make her happy. Which is also selfless in it's own way.

I also saw that some people didn't like the ending, but I had them shipped from chapter 1 myself, so I have no problem. Even after seeing the side of her 5 years boyfriend it got only reinforced for me, because he looked more like a guy who took advantage of naive inexperienced girl than actually a love interest. While she actually ends up with the person she truly loves no strings attached and who loves her back in the same way.

This is a warning for those who are planning to read this manga. You will rage...rage so much that you will have a headache..there are many times you want to punch the characters. I saw the ending spoiler because I was curious and really... I raged so much...
Spoiler (mouse over to view)
At first I felt bad for the guy with glasses, but then after reading her boyfriend's side of the story..I felt bad for him..even though I wanted to punch him for having an affair...actually every character had an affair which made me want to punch everyone so bad..but still..I wanted her boyfriend to end up with her..but no...she ends up with the guy with glasses and I wasn't happy about actually made mad.
In volume 9 they have threesome and "shares" the main girl. This part made me laugh of how ridiculous this manga and the situation had become..

Banalizing non consensual sex

A person, for whatever reason, is having multiple partners at the same time and is more or less hiding it: NTR is soooo baaaad.

A bunch of persons are constantly harassing another person to get their daily sex fix : no one is mentioning it (e.g. see the categories), let alone complaining about it.

Gendered double standards ?

This series divided many readers based on the comments and reviews from multiple websites.

It gets heavy after the premise, and becomes a plot with two guys completely and desperately in love with one girl who is conflicted with her feelings and bounces between the two.

It has a good take on why characters end up in affairs and the indecisiveness they feel. Of course, people who completely look down on people involved in affairs will hate this series and should stay away.

fucked up romance especially in the middle

first of all ive read this one a long time ago since the first four volume was released/translated but its kinda slow so i read the raws instead i dont know where it is now but im telling you its so fucked up it was good until the part where seiyuu slept with him but still didnt broke up with his BF whats after is where it gets worse seiyuu accepted them both yup it became a threesome well im more bothered by that than the ntr(got used to it because of reading too much ntr) cause i liked the mc more than the BF well after that they eventually broke up the threesome cause the mc just realized its fucked up contrary to what others say the guys only wants sex and says you can have her back lol and this is where it gets better actually after that the mc still gets the girl seiyuu just did the threesome for the mc after all when the mc quit she quit too and thats all

all in all its not that bad of a story it just has so much sex scenes well it seinen after all and its not something you can read very often

and for those who dont know there 2 types of ntr netori and netorare theyre both ntr but is also completely different netori means to steal netorare means to be stolen if you already know japanese its easier to understand thats why i recommend reading it raw its better that way if you dont want to wait

Stay away it´s NTR bullshit

I utterly hate this mangaka but i like the art his wife produces so i at least tried to give it a fair chance but you can´t built on salted land and this one and all it´s leading characters can go to hell once again. I will never touch work by Satou Nanki again so watch Nymphomaniac instead. I can recommend Living Game (8,5/10) if you are interested in a good office romance with an edge and Anata no Koto wa Sorehodo (8,5/10) is a fascinating examination of infidelity. None will bother you with double penetration porn so just look at the ratings curve and stay away.
If you don´t know what NTR is then just look it up here: omment-page-1/

Coming into this manga I thought she would forget about the whole condition and just go have sex with him in the first couple of chapters but I was wrong. Reading this manga you could see how much the main character is in love but at the same time it seems all he wants is sex. It gets to the point were you just want to slap both characters for being idiots in the first place

The angst is pretty great but it seems to quite quickly devolve into a bunch of sex. I started reading it again recently, and it recovers a few chapters in from her Nigoya boyfriend's story. At times it seems realistic and at other times it has me going 'how could anyone do that!?'

The text at the end of chapters is just beautiful, though. Major props not just to the mangaka but to the scanlators for managing to make it so emotive at times.

All it takes is one kind, gentle idiot with good intentions.

Love polygon, angsty and masochistic H-tragedy about lies, tender romantic love, painful hopeless yearning, and good intentions. VERY EMO. NO GANGSTERS, WARS, RAPES, DEATH, AND ABUSE HERE - ALL ABOUT BASICALLY NICE PEOPLE MAKING THEIR OWN MISERY. Stunning use of facial expressions and subtle touches and gestures overwhelmingly driving the whole plot.

The focal point of the M-shaped polygon is the young office lady Seiyuu Hina, a sweet, kind, supremely gentle ditz, whose weak-willed go-with-the-flow choices and penchant for compassionate lies royally bugger everything up for the five involved (as of chapter 42), especially her own... in caving to male determination, circumstance, and her weaknesses, she ends up with two boyfriends, a "committed" long-distance relationship with the blissfully ignorant mysterious "Nagoya" (for several volumes, only his city of residence is known), and a "pretend romance of convenience/FWB" (without crossing certain lines) with the dour salaryman protagonist... being always there on a daily basis, desperately in love, playing the "real" boyfriend parts, all the while constrained by rules and the knowledge of forever being a temporary #2 would be wangsty enough, BUT that's just the appetizers. BOTH boyfriends are in fact long-time obsessive love interests of two of Seiyuu's friends, both of whom are another tragic variety of love-struck naivete and bad choices. Add major flip-flopping indecisiveness, depressive angst, and Hina's tendency to try (and spectacularly fail) at telling white lies or acting fake-OK while blinking back tears (she's the sort of cute, gentle idiot to kiss the name of a loved one on a phone call...before rejecting the call, because it'll be "better that way"), for the supposed greater good of all involved, and we have a major, major mess.

lots of very vivid scenes of emotional anguish, interspersed with crowning moments of gentleness, and repetitive naive and unintentional heart-rending betrayals. all loves are hopelessly obssessive, full of delusion, jealousy, and bleak self-hatred.

NOTE: saccharinely tender love scenes with a bitterly sad aftertaste abound and the only thing more commonly seen than Hina's tears or the protagonist's bitter frowns and dejected grimaces are Hina's massive bare jugs... All in all, though, the plot and the wangst make it all rather un-pornographic, regardless. It's all about the expressions. The sad, dejected glances or hopeful puppy-love-struck stares generally directed at them just aren't particularly horny or even salacious... it's more of a dreaming of love and acceptance, go for the boobs and hope for a miracle thing.

It's all so very heartbreaking... and, very often, fits-of-rage-inducing. PROBABLY BECAUSE IT'S PAINFULLY REALISTIC. best depiction of helplessly obsessive yearning and angsty romance I've ever seen in any genre, on any medium.

It's an affair...

Can you criticize a work for its premise, I don't think so. But it does completely dump it in the very first volume so yeah. It's about people making all the bad choices. I think this manga tries to portray them a bit more positively, like it wants them in a position where you might forgive them. The hair at her boyfriend's sounds like an out, except that it doesn't prove anything and she's the one to act out as far as both she and the audience are truely aware of, I'm annoyed at these stories that think you can justify a character's position without evidence and that it isn't all in their heads. I'm sure this manga will try to justify it but it'd be hilarious if it really was just some guy's(neighbor, or group of friends with a girl). The guy's so desperate for the girl that he's uncaring about her situation(which makes him a douche). The girl's just weak(guy is too, she's a douche as well). If she can't deal with it, she should have done something about it. Still... it's plausible, people are shitty/weak afterall. I've read the other works by these mangaka(both) and she/they/he is very thoughtful about situations, but I'm not seeing it here. Though if I'm being picky the premise was that he wanted her but she wouldn't cheat on her boyfriend, I think that story would have been interesting. The story of someone actually having to move on despite the crush because the relationship isn't possible, or about someone in pathetic desperation, while her long distance boyfriend gets to do her while he acts more like her boyfriend, or a story about realizing you can like a woman and want her in your life in a way that isn't sexual. All those would have been interesting, and possible based on the premise but the story is a simpler one where the guy and girl definitely cheat, almost right away, so I won't even consider it a spoiler. because if the premise is that she didn't want to cheat, and sexualize their relationship, it totally fails, and they do lots of sexual acts.

Frankly I am disappointed it didn't even live up to the premise. The way the girl constitutes what is cheating just makes is just very dumb(but she admits it later). The emotions aren't heavy because it's never built up despite being so slow and having apparently ten volumes to tell this story(that doesn't seem to have much meat to it, I think they could have told a better story in one). And this is the weakest work I've read by these persons; the good ones, especially the artist's, *where in they truely look at something, both sides, the faults, without forgiveness or outs.

I can't overstate how thoughtless this seems compared to their other works. How lacking it is in that feeling of emotion and heavyness. How easy it is on the characters, It's not the kind of story they make because it's too simplistic, and idealized about something that's about people doing something awful.

After volume 4: *It finally starts doing that in volume four, which goes with my criticism of how slow this is for one of their works, and it doesn't change the criticism for that time. The story's also finally getting interesting. Ironically seems people who give it low scores are doing so for the manga correcting these problems(they like it less as it gets good), guess they want the crappy version.

So this work's real problem is that it doesn't show it's cards soon enough, it just takes too long with it's first three volumes and stretches what should have been one or one and half.
