Koisuru Boukun  
Login to add items to your list, keep track of your progress, and rate series!
Being in love with your straight sempai isn't easy, but being in love with your straight, homophobic, and (to top it off) tyrannical sempai can be hell! And that's something Tetsuhiro Morinaga can relate to... especially now that he's had a taste of the forbidden fruit!

Features the same homophobic brother from Challengers, but this time as the main character!

Contains an extra story called Bokutachi no Shippai in v.5 featuring Masaki and Morinaga's big brother Kunihiro.

Takanaga Hinako confirmed on her Twitter account that her manga Koisuru Boukun will resume serialization in the February's 2015 issue of Kaiohsha's Gush magazine.

I really like this series, though I can appreciate it's not for everyone. A lot of people can't get past the premise, and would consider most (if not all) of the sex scenes in the manga rape. Since I don't think yaoi is supposed to be extremely realistic and serious, I didn't mind. In real life Morinaga and Tatsumi might be considered scary, unpleasant people, but this is fiction. If you want realistic, go read Sakura Gari. If you think a love story between a neurotic, abusive, homophobic closet case and an adorable serial rapist sounds like it could be interesting, this is the right manga for you.

As for the rest, the art is good to begin with, and it only gets better as it goes on. The pace is also good, it doesn't drag or get suddenly weird later on. The story sort of sucks you in and it doesn't feel repetitive despite the fact that character development is really slow. The ending did feel a little rushed to me, but satisfying nonetheless.

I wish there were more long, quality-consistent yaoi manga out there. This one gets an enthusiastic 10 from me.

The art is one of my favorites, but I found Tatsumi so incredibly annoying in the beginning due to his unrelenting stubbornness. I'm liking him more since the story started actually progressing (just finished volume 5). I found Morinaga to be very adorable; it's hard to believe his past relationships. I just can't help but like the excited-puppy-types. I just hope the last few volumes have more going for them besides the steamy scenes, otherwise I'll be thoroughly disappointed and feel like I wasted my time with such a slow series.

Well, I pretty much feel exactly like "streetwalker", this persons comment was exactly what i think so i won't repeat ^^ But honestly i do want to repeat that the stuff about blackmail and rape is so not true. It's only the very first time it can be considered rape, since at that time Souichi was too weak to resist, but the other times have nothing to with rape or blackmail. You cannot blackmail a person by saying that you will leave them if you don't get your will, seriously. And Souichi says a million times that if he was blackmailed by anyone else, he wouldn't let them do anything. And honestly Souichi is not a weakling or a girly guy, if he seriously didn't want to do it with morinaga, he would have kicked his ass and choked/stabbed him or something like that, but he didn't! So obviously it's not rape, neither is it blackmail, it's all just an excuse for him letting morinaga do that stuff with him without resisting, just like "streetwalker" said, it's not that he doesn't want it, it's that he doesn't want to want it and therefore, the excuse of him being "blackmailed" and "raped". And also whenever morinaga looks at him that special way Souichi always gets all flustered and blushes and all that. Not exactly how you would act if some bastard who had been raping you several times looked at you lovingly -__-

So seriously, i don't understand why some people are writing those sort of lies in these comments, it's like they haven't even read the manga!

So to those people that were thinking of reading it, READ IT and you'll understand that it's a totally great, cute and hilarious manga, that doesn't have the usual rape=love plot that so many yaoi mangas have! Honestly, it's really great in every way and every chapter is entertaining! biggrin

I don't get all the fuss about non-con regarding this manga. I'd say whoever seriously thinks the whole series is some rape fantasy hasn't really read it. The first time it happened was definitely rape but only the first time and even that wasn't planned or anything. It wasn't graphic, it wasn't cruel so as rape goes this was pretty tame.

When you look at the story more closely, all the pieces click. The "blackmail" is basically Morinaga saying he'll leave if Souichi can't give him what he wants from their relationship. Hardly criminal, right? If Morinaga really was sexually abusing him, wouldn't Souichi want him gone? The only reason it's even labelled as blackmail is because Souichi needs an excuse for giving in. And the way I see it, Souchi doesn't refuse the sex because he doesn't want it, but rather because he doesn't want to want it, and there's a big difference... He just doesn't want to be a homo and this manga makes great use of the whole denial trope. I was actually more shocked by Souichi's violent outbursts than Morinaga's sexual behavior.

As for the rest, well the characters are all wonderful. Morinaga is super sweet, sympathetic and easy to relate to. There's also great character development especially when it comes to Souichi and the couple growth is truly touching. For such a funny manga this is very deep. The art is great and the sex scenes are some of the most sensual you'll ever read...

Highly recommend! ♥ And if you decide to read it, don't merely skim through it or you might just miss the whole point...

Super Rape

I honestly seriously hate this serious, it really unrealistic and even for fiction its bad. What person or persons would fall in love with someone that blackmails them and rapes them all the time. Every chance morinaga got he wanted to rape souchii . Its like the dude was sick in the head. I say it unrealistic cause i have gay male friend. and even in his opinion its bad. No one male or female would ever fall for anyone that would rape them constantly. I dont see why people love this. Cause i believe if you love this ,then something wrong. The end of story didnt end well at all. Moringa left souchii , and they both stay in to different prefecture in japan. So i dont see them as lovers. I see them as friends with benefits. Except one enjoys it more, just cause a person comes,are get hard does not mean there enjoying it .. People get rape a lot times and either or i spoke about before happens. i just seriously hated this one. She a great artist,and the some comedy was cool. But sex parts,excuse me rape parts were seriously annoying . Oh wait i forgot in volume 4.1-4.7 where masaki rape ,morinaga brother while he was chain, I justed wanted to take my pc and throw it against the wall. Come on come on, i guess yall love that too. the dude was serious he wanted to get hell out, oh and then she wrote and made him fall in love with masaki . I just think the author was have serious lusty wants , or did some weed when she tranlated on paper.

Makes you think about the line between love and friendship

Not much I can say that hasn't been said. There's some non-con issues so I can understand how it could give some people squick. But really compared to SO many other yaoi this is practically a romance, just with one person extremely, extremely uncomfortable with his sexuality. Though that's just one interpretation, it's the one I prefer. I have read various takes on Souichi's feelings and actions but ultimately people seem to agree this is a compelling manga that makes you think about the lines between love and friendship. I personally really enjoyed it because it was funny, had good characters, great artwork and great sex.

I only wish there was one more chapter.

Hot and touching guilty pleasure   
Rating: 8.2 / 10.0

An excellent guilty pleasure in the escapist fantasy genre.

The author manages to deliciously draw out the typical "in denial" trope, and have the story progress slowly and ~naturally enough, with the help of clichés all right, but somehow making it work, and spicing things up with lovely tension and some of the hottest sex I've ever read. It runs out of steam somewhat towards the end around the time they go to Canada, and the ending was totally predictable and anticlimactic. It totally took me by surprise that I'd reached the end since so little emphasis was put on the "first time they made love". Sure it ended the way I expected it to, but I was waiting for something more remarkable to finish those 8 volumes.

Still I really liked that while one "dominated" (not in a D/s or SM way) in bed, the other had the upper hand in their "public life", that the seme was the kind-hearted one, open with his sentiments, while the uke was the tyrant. I appreciated the bid for originality and tentative to break the seme/uke mold if anything else, it helped maintain a sense of balance that is completely lacking from lots of yaoi and which always makes me uncomfortable.

There were many heart-breaking and heart-warming moments when Souichi let the façade crumble and allowed himself to get close to Morinaga (I'm thinking after the fire for example) which made the whole experience really enjoyable as you got attached to the characters. The first yaoi I read when I started in the genre, and I'll keep a good memory of it.

It's a matter of taste but I understand how this manga might skeeve people, and with reason. If you're not ready or can't consider this as something related to sexual fantasies and that rape/forceful sex/dubcon isn't one of your kinks (I personally discovered that it was when first reading this ^^') then it'd be best indeed for your to pass your way.

That being said, this is no dark cesspit of morality with rape everywhere either. That the first sexual encounter is a rape is sadly a fact, and a really unnecessary one where I think the author bowed to the ~expectations of the genre
Spoiler (mouse over to view)
Morinaga could have perfectly decided to withdraw from uni after drunkenly confessing and being rejected for example, which would have set the story just as well
and it could be a deterrent for many, but thankfully it wasn't for me, because the story only got better from there. I'd encourage people who can to suspend their disbelief and put their escapist-fantasy goggles on for a short while, as the evolution of the relationship and of Souichi's feelings and behaviour is pretty good and true to character after that.

I don't consider *any* of the sex that happens afterwards as rape, because a) we're in yaoi-land, I'd be all for emasculating Morinaga if it were RL, but realism is not the point here b) in the "logic" of the story, as Morinaga points out, Souichi only seems to be looking for an excuse and c) he even admits that there's no one else he'd do that with, no one else the "emotional blackmail" would work for anyway. And also, because the sex was hot so I didn't mind so much :3 I *am* a pervy fangirl after all.

I put off reading this for the longest time because I'm not usually a fan of the big, long running series(like this, junjou romantica, etc). I have a few issues with this series, but overall I continue to enjoy it in spite of them. For a serial rapist, Morinaga is insanely likeable and easy to connect with. I feel as though they could have gotten away with NOT having him ever fully force himself on Souichi and it would have worked much better for me, but there are a lot of good points to this which make me forget. The whole thing is like pulling teeth, but I can't stop reading it. What is wrong with me?

This has to be fate. I started Koisuru Boukun a long time ago, and today I finally finished it and it so happens to be the 100th yaoi I finished. Loved everything about it, I just hope that sensei will make some bonus chapter or something and I also heard that it will be a sequel featuring Morinaga's brother, I just can't wait.

Koisuru Boukun is without a doubt my favorite yaoi! I love the humor, but I also love the serious moments. This manga is a perfect combination of both. It's heartwrenching and yet very funny. Morinaga and Senpai are both so loveable. But also the side characters and background/family stories are very likeable and add depth to the plot. And the art is simply amazing!
