A niche manga for a very specific group of readers, yet undeniably impactful

Umm.. well ^^; one thing I can say for certain is that this manga was intended for a male audience.

Initially, the theme of this manga may seem very inappropriate and disorderly, but after reading the entire manga, it kind of leads the reader to a new perspective on the manga and its theme/message.

Though short, this manga really goes through several stages within the chapters, mostly going from Acting based off of sexual desires -> Being caught and paying for the Action -> Finding love and rejecting his previous methods -> Losing that love, hence losing the one hand in his life that seemed to be reaching out to save him -> Retribution in a form of revenge and pettiness -> Coming clear about everything, trying to change -> Dealing with the consequences met from his past actions, still trying to change and mend relationships he destroyed -> Somewhat moving on/becoming a changed person, with the others around him being supportive -> Helping out the FMC find change herself -> Not dwelling on his past love and moving on, finding new love.

Now, while I don’t think this manga was a masterpiece by any means, and it definitely had many flaws to its plot and story, I think there were many parts that I did find to appreciate. Quite similar to Aku no Hana as well in retrospect.

Honestly, I don’t think this manga would be much of an impact to the majority of the audience, but to growing up teenage males struggling with puberty and keeping up with the constant changes in life, I think this manga could give a new perspective on how to deal with such issues.

The author must have bully fetish which is having feeling for his bully and I don't even fucking understand this kind of masochist tendency.

If you haven't been a misadjusted loon at some point in your life, this isn't for you. If someone told me this is a CIA operation to mark potential future terrorists I'd almost believe it.

The protagonist is effectively a very extreme caricature of a teenage loner, getting pointlessly worked up in his own head, and then committing unsavory acts toward others (not described here, because they are kind of disturbing), starting with some misguided "justice" toward bullies, culminating in

taking revenge on the girl he loves, for the "sin" of loving someone else (he "needs" it to get over her, as if there was anything to get over to begin with).

Then he finally realizes he has been a jerk (pun intended),

confesses his acts, and after going through bullying, redemption (he is almost a normal person now)! Is the arc somewhat believable? Yes. Is it a masterpiece? No. Being believable is the baseline for telling a story, it's not something to be applauded. It's also still very convenient for the protagonist that some people are willing to extend a hand somewhat early on after the "pivotal point", and the girl he ends up with makes no sense whatsoever, from a narrative perspective (unless you think people who are atoning in their own ways make for excellent pairings, no matter what the previous circumstances between them are).

So, the plot is not particularly original (once you ignore how extreme it is in certain elements), the protagonist goes from unlikable and insane to regular (nice) guy, which isn't exactly compelling. The other characters aren't one dimensional, but they don't have much depth either (the series is short and there is a lot of wasted time, so it would be hard to do much with them anyway).

At its core, it's just an unremarkable coming of age story, which meanders quite a bit before getting to the point, and doesn't give enough screentime to most of the supporting cast. Plus, you have to wade through some disgusting content early on to get there. I genuinely believe this would have been better with 90% less teen angst in it. It's a story that has been told before and better, and will likely be eclipsed in the future as well.

(nostalgic) masterpiece

Rating: N/A

Back in the day when we were kids, we read this series and got angry at

his crush dating another guy , we were frustrated when ! he publicly confessed and decided to repent instead of continuing his vengeance arc , we were devastated when he ! started dating the girl who was the main villain of the first few chapters . Those feelings are natural if you're used to the type of one-dimensional hero/villain stories that dominate the mangasphere. If you don't want to read the spoilers, just know this: this isn't a series about childish revenge fantasies and righteous punishment for school bullies. It's a story about how who you are in middle school is just a microscopic portion of your life, and you get to choose how long that person stays with you. It may sound ridiculous, but more manga should emulate themselves off of this series about a guy who dramatically jacks off in the girls' restroom every day.

Double standards, hypocritical preaching, and telling rather than showing.

by Deago

Rating: 4.0 / 10.0

The manga relied heavily on time skips and frequently failed to convey character development through showing instead of telling; major examples are failling to build the chemistry between Takigawa and Nagaoka, the author expects the reader to fill the void of said development that supposedly happened during the 40-day summer vacation; it doesn't matter whether the author intended to withhold the information about their relationship for the sake of 'plot twist' reveal, it's still a lazy writing and forced, and cheap plot progression for the sake of shock value.

Another example is the author conveniently placing that two-dimensional bully tsundere bimbo; Sugawa, in a situation where she seeks help, and Kurosawa happens to be there at the right moment, and coincidentally with the girl with whom she arguably had the worst relationship, and what a coincidence that she broke up with her boyfriend who beat Kurosawa and being available at the right time. Yet people think it's cute and natural. I'll return later to talk about Sugawa.

The manga contains a number of contradictory double standard messages, such as the author comparing Kurosawa's situation to Kitahara's because both were bullied. Are we supposed to forget how Kurosawa was ostracised as a form of retaliation? And how several other students began to sympathise with Kurosawa and assisted him in overcoming bullying, such as by providing emotional support or cleaning up his desk. Yet we are expected to be proud of Kurosawa for overcoming his own adversity while pitying Kitahara for not adopting Kurosawa's mentality and perspective on bullying.

While the manga effectively depicted the negative consequences of child bullying, it failed to maintain a sense of authenticity; we have Kurosawa's friends who supported him, such as Nagaoka, Takigawa, Pizza-ta, and Kobayashi and Erika (who were both presented as the class leaders and mediators), that's nice and all, but they all did absolutely nothing for Kitahara! All they did was watch the girl being constantly hurt and abused, the only one who noticed this was Kurosawa, who also did nothing but preach to the victim, this is an outright double-standard and makes the entire cast hypocrite.

And now back to Sugawa and her minions, who were constantly bullying Kitahara to the point of worsening her social anxieties; skipping school and being shut-in, and developing suicidal tendencies, yet Sugawa and her group, like the rest of the class, did absolutely nothing to show remorse and responsibility by reaching out to Kitahara, visiting her house, and self-admitting to that they were fully responsible for the way she acts, yet we are supposed to disregard all of that with an off-screen apology and believe that they have matured. What happened to "show, don't tell"?

Don't read the last volume

by Choror

Really good and realistic manga, but the last volume invalidates everything that was being shown in three preceding volumes. The problem can be described in one sentence - The last arc is a NAIVE portrayal of aftermath of everything that has happened to that point (it's so clear, you'll definitely notice the precise moment when manga takes the turn for bizarre)

Sick premise, but once you get to read it's has quite the depth

by Joese

Rating: 8.5 / 10.0

I'd seen it various times as one of the top completed manga but was, repeled but it's description but once I got to it I finished in a swoop. Even though many might dislike how it's drawn in pencil for me its a plus, really reminds me of when I drew and some of the textures you can obtain.(If you feel disgusted skip read ch25 the conclusion is worth it)

The MC is quite perverted but he's crazy enough to be likeable ,and once you get over the premise it's more or less plausible. It's nice how it paints all grey and depicts bulling as don not only by the perpetrators but also the incantation of others and how even adolescents haven't formed themselves yet showing their insecurities and uncertainty about the future some feel.

I feel bad on how the girl didn't go to the reunion in the end, but this and how he didn't end up either her or the one he initially got close to is what makes it realistic. Also even though the is given all the 'screen time' the actions/reactions give rest of the main cast great depth and a variety of emotions .
