From Vices and Devices:

Yumeji has a big problem, and no, it's not that he's gay (for now, anyway). Despite his good looks, excellent grades, and talent for sports, he's not getting any, and it has everything to do with the fact that he's impotent thanks to a traumatizing event back in middle school. Nothing seems to help, and since Viagra is apparently not a viable solution in Japan, he's practically lost all hope--until he meets underclassmen Seiji, who's violent, tactless, and says whatever is on his mind. Conveniently enough, he's also in love with Yumeji.

3. Koibito Kijunchi
Mu's in love with his best friend Maru, but Maru doesn't take him seriously because, well, Mu's a huge slut who will sleep with anything that moves. So Maru suggests an "endurance contest": he'll sleep with Mu if Mu can hold out for ten days without sex.

Ok, so this manga is one of the first BL manga i've read, and also one of my favorite. The first time i read it, i blushed and fangirl at every page (haha, lol)..but then, after a year, i decided to read it again, i felt that it lacked something. I dont know, maybe i want it to be a looong series like hidoku shinaide (with lots of *those scenes) But anyway, it's still one of my fave.

Superb art: ✔
Good characters: ✔
Cute story line: ✔
SHINKAI-KUN: ✔❤ (haha lol)

I thought the stories were cute. Although, there were a few times I wanted to slap the semes and knock the ukes in the head to get them to realize. But overall pretty good.

I have also read dj #1 and #3 but can't find #2. Does anyone know where I can find it to read. Thanks

Sorry but to all the readers who find this manga likeable, you need help, seriously. Sometimes I could tolerate silly stories but the ones here are absolutely horrible, they make no sense whatsoever on a whole different level. And yet the characters somehow manage to be even worse in terms of characteristics and development; they're straight up annoying and all make me want to punch someone in the face. I get that this is BL and being realistic is not what it usually stands for, but could authors for once not produce douche bags as 'romantic lovers' who in reality are just violent sleazy a*holes that force their ways through whatever to get what they need, no matter the method? This problem is even more serious in this manga since the setting's supposed to be cute fluffy school life romance, while what we actually get are manipulative nonsensical relationships, with no chemistry between the characters whatsoever. Where did all the love come from?

In short, definitely one of the worst thing I've read recently.

Sort of strange, sort of cute, and pretty fun to read. I liked all the characters, including the friends. And I adored that one of them was taller.

However, I felt like it was a bit short, and that most things were barely addressed at all. It could have been even more fun if there had been more time, I think.

I have a list of yaoi mangas I had to read and like the first five of them were so bad... I was about to give up before reading this one. However, SURPRISE. This one actually had a story (plot). It was an amazing experience reading this. Normally, I hate it when the story changes in between characters like the first story was about Yumeji and Seiji. Then, the second story was about Yumeji's friend Maru and Mu.

However, it worked. It really, really worked and it continues to change between characters, unlike where after writing two chapters on the initial characters and concluding with the side characters. I really love the concept of the younger guy (Seiji) being the seme and Yumeji (the older guy) being the uke. It's something I have yet to come across in a lot of the BL mangas I have read so far. Nevertheless, I definitely recommend this manga to BL fans. I really enjoyed it and the artwork was beautiful. I love Seiji and Yumeji's design. Maru was pretty cute too.

Finally, a yaoi manga that isn't just softcore porn or rushed into. It was captivating... enough for me. This was definitely worth my time. I hope you all feel the same way too =D

I liked the first story. It was funny but it was also plain. It didn't make my heart flutter yet I keep on reading because of the great art.

The second story... I'm not really a fan of stories where the guy/girl is a total slut. But the second story was kind of heart-warming where he/she would change his/her slutty ways for his/her one true love (or maybe you're just too hormonal to think it's love). I just really hate sloppy seconds (or even sloppy years!) I mean, how would you feel if the guy you like kisses someone and then kisses you? It would take 10 years for me to even kiss him again! Okay, just kidding. I just don't feel any love in this. sad

for some reason I've been on a shorter seme kick recently! maybe it's that they almost have to be more manly to make up for their lack of height? lol, who knows, but this fulfills my needs. =)

This felt like it should've finished after one chapter (with it getting resolved ofcoure) because the entire thing felt like drama created from nothing, not even a legitimate misunderstanding, and danced about with the same plot, or there abouts.

Even so, I liked it. It felt new, even though it clearly wasn't, and slightly enjoyable. If only the second seme wasn't there...

And I felt like the plot was lost somewhere several times and the twists in it were kinda confusing.. Also the sudden addition of a another pairing so early on was also sort of confusing, especially when it was not carried out through to the end. It felt like another hastily finished story which had a lame story line from the beginning. The characters were also uninteresting...

About the Semes

Okay I must say the story was fairly okay. After many years of reading yaoi I've realised its too much to ask of authors to make equaled relationships. Usually its a hacked-up cliche niche that they've set up, and most yaoi readers actually enjoy it.

If you're expecting a story with both the uke and seme having equal standing, then this would be disappointing you greatly. The semes (in both relationships) are cold, demeaning, condescending and hateful.

The first couple is fairly likable. A seme that is cute and dominating but childish and persevering. He apologises and at least understands some of his faults (and attempts to make good). Although the uke is far to quick to forgive and gives in very easily, its still a sweet story because the seme's continued domineering 'love' somehow makes up for it. I guess the seme came out a bit too childish and child-like so you as the reader write him off (and he is cute mind you).

The second couple made me cringe and mainly the reason why I gave this manga such a low rating. Horrible seme. Utterly disgusting. I don't see why he had to act that way at any point in time. He came of as a selfish dick. He is a good friend to the other couple, but absolutely icky with the person he 'supposedly' loves. If the first story had some 'love' this one lacked love at every level. SPOILERS

Spoiler (mouse over to view)
Chapter 3 the dick seme is asked out -repeatedly by the friend. He goes off to rant how he is digusting ... Err one thing - anyone think its absolutely wrong with the fact that is the flashback Mu got raped? It was RAPE cause the kid was underage - and his supposed friend was like - oh he had sex, he's such a sex fiend! This spells psychological shit! So fine the guy has a taste for sex, so he is slutty - EVERYONE has sex sometime (in yaoi) and why is it so wrong to enjoy sex, men have sex all the time, especially in youth, nothing wrong with it, but he seems to blame him - and even say "I don't want your leftovers" how much more condescending do you need to get Bitch? So he plays around, everyone does. If you want him to be serious about you, do something about your half-backed attitude FIRST. So he asks him out - says he loves him, then he sticks it in so it bleeds (do you know how painful that would have been?) because he wants him to cry like a virgin? BITCH I want to cut you up right here D< ARGH! Disgusting!! He was so disgusting. Has a terrible attitude, a total dick, he doesn't 'love' his friend. In fact I got a feeling he was just venting his frustrations over the other guy. Meanwhile Mu was so endearing. He said he'd make up for it with love. He tried so hard, of course he was promiscious but that was probably due to being RAPED in childhood... Bleeeh this story serious sucked, the Mura guy I hated each time he appeared, nothing good came out of his mouth. He enjoyed teasing the other couple, and abusing his friend. Total asshole - and don't get me started on the extra where he is all like - I needed to test you so I kissed the other girl because you are so promiscious! Okay the end. I give up. So much ent up fumes !!!
