Think of it as another perspective. (Alas, I don't expect people to stop burning me with fiery pitchforks.)

I read this first before Junjou Romantica, and... After reading Junjou Romantica, THEN this again, I arrived at one conclusion:

No one has friends here. You know, that kind of close friends you can talk about anything, ESPECIALLY your troubled love life / resurfacing first love of catastrophic past / your brother's best friend who actually liked your brother THEN started molesting you THEN started falling for you THEN you started falling with him.

How lonely. And no, definitely not cultural. One person, completely understandable. Two, okay, homosexuality isn't really accepted. I understand. Three, still fine. Not everyone in Japan has lotsa friends, moreso for accepting friends. But when almost all characters of the entire series + another series related to the work before all exhibit the same anguished, tragic, forcefully hidden under every rationale possible, all wrapped in denial, explosive love (or rather, the tendency to hide it and not talk about it until the worst possible moments).....

Milked for drama. I mean, think about it, a LOT of the tension presented in both series can be fulfilled without much (delicious, but still, artificial) angst if they talked to a friend who can then slap them in the head with a paper fan while yelling "BAKAAAAAAA! THIS IS NONSENSEEEE!!!". Or having a heart to heart talk.


And that's the bad part of Sekaiichi Hatsukoi -- in one word : pacing. Junjou Romantica only got like, 2-3 volumes (in which it alternates between different people and different personality and more especially, different kind of resolution) of The Masochism Tango + Belligerent Sexual Tension before going straight to Tsundere area. Sekaiichi Hatsukoi got like, 5 straight volumes. WITH Tsunderes on both sides.

Meta-wise, that's a bit...oi. Well I understand there are certainly progress (and sex. Lotsa sex.). But....exactly that point. I felt a bit cheated. Also a bit nonsensical (albeit sure, I can chalk this to suspension of belief)
Story-wise...dear God, poor Ritsu. He's broken and atm I don't wish for Takano to save him with The Power of Love, as much as for anyone to drag him to a therapist. A lot of psychologist could have a field day with his denial alone, not to mention his inferiority complex. Not to mention his mental avoidance towards 'proper healthy relationships'.

Other aspects, eeh. Standard fare of Nakamura Shungiku. Fans will come like piranhas, detractors stays 30 feet away.

I sure like the manga publishing aspect of the story, though, but I dunno....within the rose colored glass of Nakamura Shungiku's world, which is glossed over, and which isn't?

And thus, I'm done with my long perspective (ranting?). I'll follow it until the end, but just for the sake of a much-needed closure.

Tell me cheesy, but I find the theme beautiful, and actually has something to be aimed for. You might find the uke annoying with all his denial (oh come on, Junjou-roman's Uke was already quite annoying, but at least he still shows his seme some love and affection) and pull-push thingie.

IMO A kind of manga that cant be pinpointed what's so special about, but makes me follow it diligently.

So far I'm really liking this. I love the setting! Personally, I prefer this over Junjou Romantica big time. The "First love" concept is simply refreshing and sweet.

The only problem i have is the art--- the way she draws older men bugs me a bit how the mouth is so low and the chin is so narrow, but other than that i like the art. This is potentially my second favorite yaoi manga ;D (Yellow being the first) Btw, i also recommend checking out the anime. Its nice to see the characters actually in action, and i went through all 12 episodes in a flash TT.

At first when i saw that this series was an anime (after no liking the anime very much for junjo romantica but still love the series) i wasn't going to give this a shot but after a yaoi friend recommend it to me I finally decided to give it a shot and after watching the Ova i'd die-hard and read the series up to vol 6. ch 11. I have to say that in my opinion that this is better than junjo romantica with the plot and with the characters. Again 3 couples are inttoduce like junijo romatica and are parelle with one another as you see the the main character, ristu is the son of the famous onodea company who publishs usagi-san's(from junjo romamtica) and features isaki(also in junjo romatica that similar to ristu's case in this story) The character's are simialar to junjo romtica with 2 of the ukes (Kisa shouta, and chiaki) who looks like misaki but eye color, and hair style different. Artwork like many 0ther said is better.
1, (Takano x ristu a story dealing with love in the past but resurfacing again after 10 years)Couple and to me is the best couple Takano x Ristu is a couple who was dating 10 years ago for a short time, and broke up due to misunderstandings by Ristu who would watch Saga-senpai (old name) in the libaray and love him for he saved a cat when no one else would dedpite no getting to know or knowing his personaity. After 10 years later Ristu mets Saga-senpai again but could not reconize who he was because his name name was changed and he had other problems. unfortunately for Saga-senpai who also didn't reconized him at first due to his last name which was “oda ristu” which was a fake last surname he added because he was embarrass to put his real name but want to stay conntect with saga-senpai, finds out who ristu is and plans to make ristu fall in love with again despite ristu. who doesn't want to fall in love with him.

2, couple Chaiki x Hatori (Cute couple dealing with childhood friends)
Chaiki is a male Author that writes shojo manga. He being a male is drawn into his childhood friends who love him but he thinks they're in love with each other. One of his childhood friends hatori is his editor but chaiki takes under a female name due to female fans being dissapoint to find out he is a male (Chaiki thinks thats) tells chaiki that he is in love with him and tells him that they can't be together anymore due to the fact that he spoils him and that he was the only reason to get close to chaiki. Chaiki however accepts his feelings but hatori only thinks that he loves him as a friend. Yuu, another childhood friend is rivals with hatori to win chaiki heart as well.
Sadly this series is in Novel only
3. couple Kisa shouta x Kou Yukina (Another cute story and couple that works on if a beautiful love such as this could hold on) Kisa shouta, who is also a editor like ristu and works with him is a 30 year 0ld man who falls in love at first sight at a man in a bookstore who is get shojo manga that he has read and loves sold to a bunch of girls that love him and find him beautiful, Kisa loves him but it's cause of his face that he loves and believes that a person like him could never be with someone like him. Later he is caught in the bookstore stalking the beautiful man again by Yokazoa (i believe) and introduces kisa to him. Kisa gives the man his card but is sad to find out that he does not reconize him for he has met him before, but finds out his name is Kou Yukina. Later another guy finds kisa, who is about to leave the store in sadness is stopped by him cause he wanted to get back together with kisa. Kisa explains that they'd on slept together once an that was it for them. The man wasn't giving up but is stopped by the beautiful man and is told that there is no fighting in the store. Kisa encounters the beautiful man again in a coffee place (i believe) and turns out that all the books that he'd been selling were from the same editor who is kisa and finds him amazing to make him cry while reading his books. Yukina also asks him for his age which surpise to find out that kisa is 30 and he is 21. He also says that he want to create a fair to sell all his books that he loved to read which kisa is surprise by his kind words and starts to blush because of it. It turns out that his words makes Kisa blush leaving Yukina seeing that and kissing him in the store.
Anime and Manga are just amazing to read or watch.
I have to say these 3 stories a nothing but comdey and hardcore happy scenes that actually leaves hardcore Yaoi fans and guys who actually don't watch yaoi wanting more.

Wonderful Story About 2nd Chance at True Love

I did enjoy Junjou Romantica but I was totally blown away by Sekaiichi Hatsukoi! I personally think it was leaps & bounds a much better work. I love the settings - the manga publishing industry; it is neat to be able to look at behind the scenes workings of one of my favourite hobbies. On top of that, I simply adore the main couple Ritsu x Takano. I think Ritsu is the most likeable Uke of all sensei's works so far. He is funny, head strong, intelligent & very refreshingly honest with his feelings even though it comes out in blurts of unintentional confessions sometimes. The story is somewhat more realistic too - the fact that both characters obviously dated others during the 10 years break. I am very much rooting for their second chance at this true loves. I also hope that despite the trouble at TokyoPop currently, this manga will get its much deserved English translation, publication & sale in US. Any publisher can't go wrong by hitching its wagon to this series of NAKAMURA Shungiku after seeing the success of long running series such as Junjou Romantica.

It has romantic moments and the characters are likable. Easy to read. But sometimes it gets unbelievable how far into rape territory some of the scenes get into and characters just shake it off as something that happens when you're falling in love saying "oh, we have a normal subordinate-boss relationship" when he clearly forced sex on the guy. WTF? Maybe that's just me. Or maybe it's just "welcome to yaoi" where normal rules don't apply.

A lot of people have been saying that the art has improved - which is true, the art is not what you see in every day standard manga. its got a distinct style and you could spot it a mile away from all the rest, i personally love the style.

the story is great too - the uke is one of my favs too, he stands up for himself

[as of volume 4] i also consider this to be better than junjou romantica, for several reasons: yes, the art is better, and that matters to me a fair bit, because i like manga best when the art and prose are both integral to the story. furthermore, the setting is realistic and really interesting to me -- this gives a better look at the manga publishing business than the highly praised bakuman. and i actually like onodera and takano; they're not annoying, screechy uke and overbearing, kichiku seme. ok, takano is a tad overbearing, but he actually has onodera's best interest at heart, really helps him when it comes to editing, and actually tries to communicate, which is a far cry from usami akihiko. i like onodera's inner dialogue better than misaki's as well; he's not as irritatingly clueless. and the humour is wittier and less obvious, which i like better.

kisa, on the other hand, is already getting on my nerves. his inner dialogue drives me up the wall. he doesn't DO anything for his relationship, but wastes time and energy on angsting, second-guessing, and bemoaning the fact that yukina is so understanding instead of jealous.

as to falling in love with somebody one doesn't know and how realistic that is: very. people do this all the time. they get attracted without knowing much about the person, and then they think that this is love. infatuation isn't really love, at least it's not the sort of love that lasts -- which is obvious when you observe how often "love at first sight" falls apart easily. where BL is pure, unrealistic fantasy is in pretending that this sort of infatuation is always successful, and will result in happily ever after, even if 10 years have passed with the people separated.

and yeah, DP -- fabulous scanlation job. i always hope these guys pick up series i like because they're so professional, so much so that they beat most commercial translations.

I really love Nakamura sensei's works! and this one is really awesome! the plot is funny and cute^w^..well I think it's not fair to compare it with Junjou Romantica because they are a bit different (and I personally like both of them *_*)
in my opinion this time Nakamura was able to draw a very interesting uke(Onodera Ritsu), I like his personality >w<and I also love Takano san*ç* but I can't stand Yokozawa è_é he's hateful and nasty and he really pissed me off!!!
well I enjoyed it a lot and I'm looking forward to reading the next chapter X3

Wow. I had NO clue that this was from the same author as Junjou Romantica! xD No wonder Takano looks similer to Usumi!

Anyways, I prefer this to Junjou Romantica any day of the week! The drawings are definitely improved and Onodera's personality is more likable then Misaki's(in my opinion). So that's a big plus, I always loved having head strong uke's.

I think the story is great AND realistic, the drawings are amazing, the characters are great, and I cannot ait for the anime to come out this Spring!
