I honestly hated this work. And I think my issues are similar so others I've read, but I also have a different perspective on them.

What this comes down to is it reads like the author got bullied by their publisher.

In the beginning, it is made pretty obvious that Tai is in love with Touma. Like, OBVIOUS. Sure he is also envious of Touma, but that's in addition to his love. The rest of my comments are heavily spoilers but I recommend reading them before reading the series anyway.

Spoiler (mouse over to view)
So as I was saying. It's obvious. He doesn't like Futaba because she is meek and reminds him of himself. He loves Touma but is envious of all that Touma has.
But then you hit a chapter where it seems like the publisher came to the author and said "Look, we can't have a gay romance story, it won't run long."
At which point, suddenly we get reference to Tai actually almost hating Touma and suddenly loving Futaba. It's a complete 180 and it comes out of nowhere.
Futaba herself is a horrible character. Not because she's meek or clumsy or a typical shoujo heroine trope, but because SHE DOESNT LOVE EITHER OF THEM.
We're basically told to believe she loves Tai, but that's not what happened. She admires Touma and she's friends with Tai. For some reason she decides she needs to be romantic with one of them, and forces herself to choose one to date, and decides she'd rather date Tai.
There's no love there. He has equal standing in her eyes as her friend (whose name I can't even remember but it begins with M so I'll call her that) which is shown with the whole university plotline.
Yet she doesn't want to lose his love so when shit hits the fan she decides to stay with him. Even that wasn't because she liked him too much to give him up, it's because Touma told her to stay with Tai.

The argument with Touma's friends and the whole discussion that takes place in their room is sickening as well. Yes, there are two sides to a story, but trying to justify an assault due to bigotry is ridiculous. I've been assaulted a lot in my life and I've never once decided that all men are like that and disgusting. You can't say that's a justifiable stance to take ESPECIALLY when you're supposed to be close friends with the person.
By the time we get to the ending, I wanted to erase this whole manga from my memory.
Even though it's labelled shounen ai, by the end all non hetero relationships have been completely erased from the work.
M states early on that she tries to be normal and date men but she can't make it work, she only likes women. But by the end she is somehow doing well and is married to a man.
Despite making the Touma character be the only one to truly show love throughout the series, we not only get deprived of seeing him in the ending, we don't even really get to see his happiness AT ALL.
We get a picture of two wedded hands holding each other. Ok great. They got married. Touma gets no lines, no kiss, no acknowledgement. Just a held hand.
This after we're told he had to put up with the 1 year shown, the 2 years Tai and Futaba dated afterwards, and the 5 years of Tau "not being over Futaba". AT LEAST 8 YEARS he had to watch Tai pine over Futaba when neither actually loved each other.
Not only that but the author dared to write a line like "it was obvious Tai liked you from the start". What? No! Tai was uninterested, malicious, and pushing Futaba toward Touma while obviously loving Touma at the start. GRAAAAH.

Its a classic example of a writing just writing "yes x loves y" instead of showing it with any actions or gestures or anything meaningful. It was a complete waste of time reading this.

Honestly, it is NOT a shounen ai. Its not even suppostive of the LGBTQA+ community. It doesn't depict them "struggling with their identity" but rather erases Tai's and M's and punishes Touma's.

It was extremely disappointing and a huge waste of time to read.

Best romance manga i've ever read
I think this Kaito guy has a really extraordinary talent

I couldn't possibly count how many times i cried while reading this manga... (maybe more than when i read kimi ni todoke...!)

About the ending, to me, it's just the author's choice, i feel like there's no liking or disliking it, it just made me think about what this whole manga is all about... life can be disappointing sometimes... i would have wanted to see another ending to be honest, but the spirit of this manga teaches me to take it as it is, as someone else's choice, as a turn of events, or as a really great love story, and it really did make me think a lot about life afterwards,

So i say congrats to Kaito-sensei, I think that's an awesome masterpiece you gave us, THANKS !

A Literary Masterpiece that Transcends Cliches

I guess reading so much cliched and unrealistic BL, yaoi, and shojo has really rotted the brains of a lot of readers, huh?

This manga plays with and subverts the common tropes of shojo. Who gets hurt trying to save Ichinose? Who is the childhood friend of Ichinose? Who walks around the cultural festival with Ichinose? Who knows the heart and soul of Ichinose? The fact is that Ichinose ends up with the character that loves and understands him the most.

This is a painfully realistic depiction of characters questioning sexuality and gender roles and struggling with feelings they do not understand. The ending DOES NOT come out of nowhere. It is not rushed. Did readers even pay attention to the nuances? The way Ichinose looks at Touma? Go back to the haunted house scene and see the panel in which his hands touch Touma’s chest. It’s at this moment that he becomes sexually aware of Touma for the first time. It’s a parallel to the scene in which he holds onto Touma on the train, but intensifies the sexual tension.

It should be pointed out that Ichinose is NEVER repulsed by Touma’s admission of love.

The time jump makes sense, thematically and narratively. Do we really need to see the moment in which Ichinose expresses his love for Touma blatantly? That only happens in cliched shojo and BL. There are several scenes wherein Ichinose acknowledges that his feelings for Touma might be more than friendship. Go back to the scene wherein he opens the charm. It’s just that Ichinose’s feelings are not spelled out. This manga does not treat its readers as children, thankfully.

If you want to see a scene wherein Ichinose says he also loves Touma, then just go back to your cliched shojo and BL. This is not what this manga is about. This manga is about the many unexpected paths that we take in life, and how life and people never turn out in the ways we expect them to be.

This is extremely well written manga.. until you hit the ending. The ending really does what it's supposed to do but in such a bad way you wonder how did this even happen? I'm not sure if the last chapters were written by the same author.

I don't get it, from volume 1 on page 161 you can see the chemistry between both male characters, what's the disappointment? Stop giving it such a low rating.

Doesn't expect this into a gay manga, but I would still recommend it.

I honestly didn't really expect this manga into a gay romance. I have a feeling though, when Ichinose told Futaba what was Toma's type, because what Toma described were all the opposites of Ichinose.

Well, not that I hate it. In fact, I love it whenever there are positive representation of the LGBT community in the popular culture such as this one. I'm not LGBT myself, but I know how (at least in my country) they were always poorly represented in the media. And this is why I don't really like the yaoi/yuri genre, since I feel that this type always oversexualize the story and character. Thankfully, Blue Flag isn't one.

However, to be fair, I was also a bit disturbed by the ending. Like the previous review said, I don't understand why Futaba and Ichinose broke up, and why Ichinose suddenly got married with Toma. It feels rushed with no clear explanation.

However, I will still give it a 9. I honestly kind of like how the pros and cons of those who agree/disagree spoken here. It's well narrated that it doesn't feel like the kind of debates you'll find in social media. Lol.

Left Me a Little Angry

I absolutely hated the ending of this manga, but it's some thing that could have been easily fixed if the mangaka didn't do a time skip, we need that build up to how the characters ended up where they are, having it so it's a happy ending just for happy ending sake leaves a bad taste in my mouth.

Spoiler (mouse over to view)
Taichi showed absolutely zero interest in dating a man yet he ended up dating Touma. Where is the build up to that? Where is the explanation as to why they ended up in that relationship. Futaba marring a different man makes sense since not all high school relationships last but it would be nice to know why they broke up. We as an audience can infer all we want but it feels unsatisfactory that we'll never really know the reason behind everything.

TL;DR- For a manga that has great foreshadowing the ending was way too abrupt, felt like it gave me whiplash.

I reread this so many time and I love the ending tbh.. i reread this again today.. and its always amaze me.. i cry, i think i just hope i can see their progress in relationship huhu, and the ending is really waw for shounen manga.. and i love it, i reread this more than 20 times already and when i read again and again its implied that Taichi already like 'likes' Touma from the start but he dont know what is it he feeling, its shows in his gesture and else.. and in the middle of stories he fall in love with Futaba and in the end he fall out of love with Futaba, Taichi and Futaba goes separated way and Touma with Taichi in that time and then Taichi choose Touma in the end, bruh i wanna see their wedding too.. and its implied the rings in Taichi hands.. tbh i love all character they were very well written.. but yea i still wanna see Taichi and Touma relationship progress huhu

Mixed Feelings

I feel like this manga started out really strong, and there was a period of time when it felt like every chapter hit the right points, but then a certain event happened that made me lowkey put it on the backburner (and I'm not referring to the ending)...

Spoiler (mouse over to view)
Namely, I think the author REALLY mishandled Touma being outed. Like, the reactions of those around him were realistic, but the way the author framed it as if it was understandable to be a homophobe, and that the guy had the *right* to be disgusted. I was legitimately pissed off, just like the girls in the manga.

And it was also around this time I read the vastly superior Kanojo ni Naritai Kimi to Boku which also had moments like this, but whenever it happened, the author actually treated it with the gravity it deserved, and while it acknowledged that people are going to be ignorant, it never let off those people for the hurt that they caused, even if it was unintentional hurt. ...Unlike what I felt was happening in Blue Flag at the time. (And I still never felt as if the author adequately addressed it here.)

However, after hearing about what happened with the ending, I came back to it, and... Hm, I still don't know how to feel about it. I don't agree that it shouldn't have happened this way (I'm glad it did), but I also wish there had been more buildup. I feel like the author had an ending she wanted to reach, but she didn't know how to reach it, which is why it felt so clumsy.

Spoiler (mouse over to view)
Also not a fan of what Masumi's husband said about how he didn't feel secure when she's around either women or men (because she's bisexual I suppose? another nitpick: author never uses the word "bisexual"!! ugh). And that he doesn't feel like he "belongs" entirely now that he's dating her, which made me go ??? why is her bisexuality all about you?? But, again, I think this might be more of the fault of the author's framing than anything. Man, this manga... so many little missteps that just add up...

I guess this is just one of those series that I'm just going to feel ambivalent about.
