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 see that many people have issues with the first volume and I quite disagree with that. Because I see that quite often the many mangas and this author likes to address this issue and lot of her spin-offs for the series and it's kind of like even though he did such a thing to this character this another character can still forgive him because he still cares for this character. And I'm not trying to say reapers is okay but when it comes to Yowell a lot of times it is rape which don't get me wrong I do get turned off by the or I do end up skipping it but for this service I continue to read it especially after reading her previous work Challengers and I enjoyed in period but with the sauce if she really has a good town of riding her serious and I would definitely recommend continuing to read this because it just gets better it may start out rough at first but it just keeps getting better especially the while I'm 9 and the fact that the author can't give up on these characters and still writes this makes me happy to know that she still continuing to read this series.

The anime put me off. I wasn't satisfied of being disappointed, so I kinda checked the manga. And really, rape on the first few chapters? Ermm yea. The uke is too tsundere in his own good, and the seme raped the uke in the first place. Yea yea, kinda like the uke's fault for dropping his guard (victim blaming; 50-50 on this issue imo) but if he (seme) had his love controlled (which proves greater love), then I would honestly praise him for that. But he kinda lost it in the second chap so no. Quite confused why a lot of people praise this? I guess this situation is similar to Nozomu Bekumonai where a lot of people loved it but it kinda start at rape idk.

Kinda a reminder as a general, and not just for this manga.

(One of my main issues of yaoi: rape and violence is taken very lightly. As a fellow BL-lover, I advise you to please please have some standard for Yaoi.)

In my top 3 yaois of all time, Koisure Boukun earned its place from the very first chapter. I started reading it when vol 5 was out and waited patiently for each chapter to be released. Now in 2017, however, I feel like despite the time passed, Tatsumi's feelings haven't developed into love.

We see him trying to compromise with Morinaga (my pure, innocent baby) but he still identifies as straight, he avoids the issue addressing their relationship, he hasn't initiated intimate contact since the last chapter of vol 8 and that was an one-time-thing only. Literally, the only thing that has changed was Tatsumi's pleasure points and he gets to have the best from both worlds at this point.

Morinaga, who has always met selfish partners his whole life, cannot even hope to find a partner that loves him back for who he is and this breaks my heart even more. He was so happy that Senpai remembers his name now, that he tries to explain some of his actions even though in the past he didn't bother at all. He brightens up with the simpliest things and this is sooo angsty for me as a reader.

Morinaga gets to "sleep" with him only after a lot of sweet-talking, going on and on about how kind Senpai is and how much he loves him and in return he gets to have sex with no real feelings attached, where he does all the hard work ina body-worshiping kind of way, and even if they happen to sleep together after the act, Senpai hits him and acts cold as soon as he wakes up under the guise of being shy and not comfortable enough. I expected more things from Tatsumi.

However, at this point, even though Morinaga swallowed all these insults and abuse and apologized to Tatsumi a thousand times (he replies with an "I'm sorry" almost every other panel) for being gay or for wanting more and even though Morinaga confessed in the most endearing ways and had tons of sex with Tatsumi, it breaks my heart that the only thing he has accomplished is being Senpai's assistant at work, housekeeper and personal whore in bed. He deserves a lover that feels the same way and treats him kindly and passionately and acts stupid-in-love.

Since Morinaga is my personal favourite, I can only wait to see how Takagana-sensei can resolve this situation in a positive way. As a fan, I'm very dissatisfied with how things are atm.

Sometimes it got annoying

I hated how Souichi would act Tsundere. No, there's no problem in being tsundere, but he just overdoes it. Throughout this manga, I felt as if Souichi's tsundere-ness creates problem in their love life. Just give Morinaga a proper answer already!
Spoiler (mouse over to view)
5 years of crush, and then you say "I don't know" to his question
even though it's obvious that you're in love with him and you know it by yourself. And morever, how is he a "homophobic"? He is not a homophobic at all. Like I said, he is a tsundere. And he couldn't accept the fact that his brother went abroad with another man and also got married later on. It looked like he kinda had some brother complex or something. Whatever, he couldn't accept it, that's all. It didn't really look like he hated homos at all...Not after you be a homo by yourself.

Spoiler (mouse over to view)
In the 1st chapter (and/or int the first OVA) he asked Morinaga if all the homos are together to annoy him (or whatever, didn't care to remember every single line).
What the hell man? Why would you ask him? How does he know? He shouldn't know that ONLY because he is gay! It made me actually happy that
Spoiler (mouse over to view)
Morinaga got irritated (for the first and last time) and went away, or tried to go away. Souichi deserved that.

Though, I'm just waiting for Souichi to confess his feelings. Man, you can't be this shy, right? His shyness and tsundere personality made me feel that he was born to be the bottom aka uke. The art is nice, though not the best. I liked how both of them developed though. Just waiting for it to get finished.

This is one of my favorite romance stories, both main characters are absolutely endearing an well rounded. The story is heart-moving, interesting, exciting, thrilling, it is easy to relate to the characters, sex is a plus not a main.
I'm a straight girl and I find this absolutely amazing, if you like good romance, whether you're straight or not give it a try.

Note* There's a lot going on about trivializing rape, I think this is nothing more than a fantasy, and that in this particular context (of this story and erotic stories in general...) it doesn't exist the final component of REAL rape, which is simply that there's a victim who ABSOLUTELY doesn't want sex, and an aggressor who ABSOLUTELY doesn't give a sh*it about it.
Spoiler volume 1:
Spoiler (mouse over to view)
The one who was forced ended up (almost) accepting that he liked the forcer and that he preferred him in his life rather than out of it and actually chose to keep having sex instead of loosing him. It kind of translates as 'I like you, but I'm in denial, and if you wouldn't have forced me I couldn't have dealt with my feelings' so... Reason enough for me.

The glasses guy is supposed to be homophobic, but that didn't look like homophobia to me at all. Of course, I don't expect him to be a total jerk about it or something, but he looked more like a tsundere instead of a homophobic e_e

Srsly tho, rape right in the second chapter?!!!!!! No thanks, rape isn't something to be taken lightly like that. ugh

Totally unrealistic tbh, already dropped after reading the third chapter.

#CONTAINS SPOILERS# The drawings are good, the characters have well rounded personalities... But the story begins with rape and that was a total turn off for me. One character is drugged, cannot move and gets raped by the other. It reminded me of Ghb stories. Later the rapist say he's sorry but that it's also the victim's fault for disregarding his feelings. That made me shiver, seriously. I couldn't suspend my disbelief enough to accept someone would forgive their rapist and let rape be trivialised that way.

My Second Favorite Yaoi

Was the third yaoi I ever read and I initially hated it because of the homophobia and rape scene. I hate those kinds of yaois the most.
But I came back eventually and fell in love with the characters. They're so believable for me. I even read the original story Challengers which I don't like as much though it explains a few things that Koisuru Boukun didn't bother to. Souichi is adorable and I fell like I can connect to him, while I just want to hug Morinaga and pat his head like a good kouhai.
While I can see why people wouldn't like the series, I think the progression is very believable and realistic. And as for the arguments that their relationship is mostly non-con, then you need to be able to read subtlety better.

A must read!!! Trust me, lol.

One of the best EVER series - hotness in combination with humour. Tatsumi, the more hottie of the two main characters was so bang-able. He was beauty reincarnated that seriously no other manga babes can compare. What does he have going for him? Um,… only the best face and body that’s ever existed in yaoi manga. There is no better face or slender body. Sorry, there’s not. And those hot damn glasses….Ugh. THUD! I so have a kink for guys who are half blind. Tatsumi was so fragile, so vulnerable, but yet so fierce. Takanaga did wonder with this character - making him so three dimensional.

I liked that there were layers and depth to Tatsumi's emotions from confusion, anger, fear, anxiety, and finally love. Morinaga was wrong by forcing sex on Tatsumi, but then Tatsumi forgave him. That spoke volume that deep down he loved Mori. Tatsumi then went on to let Morinaga "black-mailed" him which led Tatsumi coming to term with his sexuality.

I also loved that Tatsumi was no damsel in distress even though his beauty made him seemed so fragile. Tatsumi struggled, was confused, but he did it all on his own term and his own pace so bravo Takanaga Hinako for making him so alive. I'm keeping toes and fingers crossed for more of this fantastic series. MUST READ!

One of the best yaois there is. Really like the development of the characters, specially Souichi (aka.
Sempai). Perfect combination of the comedy with the drama, and if you really get into it, you will cry.You can either love it, or have it.
