Summary

The following content is intended for mature audiences and may contain sexual themes, gore, violence and/or strong language. Discretion is advised.

Sekaiichi Hatsukoi ~Onodera Ritsu no Baai~
Onodera Ritsu has just transferred from his father's publishing company to Marukawa Shoten. Assigned to the shoujo manga division, he crosses path with the person he'd least expected to meet. Takano Masamune is the editor-in-chief of the division Ritsu's been assigned to, and the two seem get off on the wrong foot right from the very start when Takano unexpectedly kisses him. However, there is more to than what meets the eye: Takano is actually Saga, Ritsu's senpai and high school love-- whom Ritsu had thought to have played him for a fool by taking his affections for granted when he confessed and summarily dumped him. (from zero_kiryuu)
loosely connected to Junjou Romantica (Usami Akihiko's name's in here!)

Sekaiichi Hatsukoi ~Kisa Shouta no Baai~

The second story tells about Ritsu's colleague Kisa Shouta
who works with him at Marukawa Shoten's Emerald shoujo
manga department and ever smiling, suave and irresistably handsome Kou Yukina.

I love the manga way more than the anime. Reason being, the amount of sexiness.

    When is the latest chapter release of Sekaiichi Hatsukoi??? Do you know any site that has the latest raws or this manga will receive no updates because it is already licensed??

  5. resonance27 March 23, 2015 11:06 am

    Things are getting interesting now. I thought that Haitani got feelings for Takano, but now I knew, will he really fall for Ritsu? I know he's still playing right now. But who knows, later... ε=ε=(ノ≧∇≦)ノ

  6. Glass Heart March 20, 2015 7:15 pm

    I just noticed this when I was re-reading it again.. ristu was actually planning to confess here but takano cuts him off... So its like the 2nd time he got interrupted. Ritsu admitted already his feelings for him but by some weird circumstances brought by the power of mangaka, it was always interrupted..

      Nice observation... yes, he planned to confess twice.... 1st.... the scene where takano run after ritsu and got stranded in a waiting shed or something like that because it is raining and both of them don't have any umbrella.... I can relate to Ritsu because he gathered up all his courage to confess and then bang!!! The rain poured so strong that Takano can't hear him...... 2nd.... when Takano went to Ritsu's room or it was vice versa I don't clearly remember....... When Ritsu kissed Takano's hand and he almost confessed but Takano kissed and dragged Ritsu to a sofa and you know what is next......

      I think Ritsu's problem is that he is afraid of what will happen next after a confession and his trauma of being played....

  7. Rittie March 20, 2015 1:47 pm

    I'm honestly pissed. Just read the extra booklet and it contained all canon couples (at the time) except for Hatori x Chiaki. Why are people condamning Hatori over one act that never happened again!? -.-

    • Mira March 20, 2015 2:31 pm

      There is a extra booklet?

    • Rittie March 21, 2015 11:47 am

      Vol 3 chapter 7 or something like that, yeah. They scan group literally stated that they won't be translating the HatorixChiaki part of it because Hatori raped Chiaki once. Doing it once seems to be a death sentence or something -.-

  8. Serara-mi March 20, 2015 11:03 am

    i always find myself read this manga over and over again, but its feels like it was never enough. i really like Takano x ritsu. and i want more chapter about kirishima x yokozawa. reading the novel feels like wasnt enough. and while reading novel makes my imagination go wild for every sex scene (๑•ㅂ•)و✧ now im confuse who the best seme, at first i really choose takano, but seeing kirishima would be my ideal seme ლ(´ڡ`ლ)

    everything is according to the plot. the ending point in this story will be the confession. if you want ritsu-chan to confess then don't expect to relish another story of their day to day lives. and as you can see it has days counting down before completely falling in love and confessing. just wait a lil' more guys nd enjoy every moment of their love story(づ ̄ ³ ̄)づ.

    Onodera is really lucky to have Takano around and moreover Takano really loves him so much.

    Well we can't put a blame on Onodera that he won't accept Takano's love so easily because of the misunderstanding. I'm glad that Takano is finally opening up his past to Onodera in order for him to completely fall in love with him ALL OVER AGAIN. (づ ̄ ³ ̄)づ

    Still waiting for the update!~

  11. Anonymous March 13, 2015 7:19 am

    Well, I say that Onodera is damn lucky that Takano is so obsessed with him. I actually am getting quite fedup with Onodera behaving like that, playing hard to get, is he? just when Takano always seemed to be declaring his love. Even if he has no confident, couldn't he see for himself the great lengths Takano would go, to try make him happy?
    I'm getting pissed off, if he still doesn't assures Takano soon, let all hell loose..make Takano leaves him for a certain time or give Takano an admirer to make him own up his feelings. Ah, I'm sorry, I'm just so irritated.
    And for goodness sake, quit that blushing always, I can't stand guys like that, it's just too girly....

      got to agree with you it's the same with misaki in junjou I'm really beginning to believe sensei doesn't believe in letting her main uke's have a smooth path to happiness and enjoys making them angsty little women I'll admit I haven't read the latest updates to this or junjou yet but judging by everyone's comments unless sensei changes direction quickly she'll lose her readership

    • Anonymous March 13, 2015 8:56 pm

      Right now takanos fault too for beeing so bothered by every little thing i mean he even wanted to tell haitani that he loves someone other but takano stoped him beacause of his fear to lose him and all in all he's too worried and doesn't see how his pushing and rushing drives onodera so crazy and makes him so unwilling to say i love u again

    • (=・ω・=) March 14, 2015 2:43 am

      actually, everytime onodera's about to confess, he keeps on getting interrupted.

      yeah poor onodera qwq and then everybody compalains that he should be honest about his feeling -.- i feel so sorry for him TwT

    • Lala March 15, 2015 2:53 pm

      Ritsu wanted to confess a few times, but then sometimes Takano interrupted, or one time the rain was loud and so... But in the last chapter Ritsu hugged him and gave him a BJ xD For me he seems a little more matured than he was. I really want to know, whats gone be happen in the next chapters!! ( ̄∇ ̄")

    • Xxania March 18, 2015 7:15 am

      Lol, it's just yaoi. Get over it. Besides, that's what makes their relationship unbearably cute and lovable.

      March 24, 2015 1:42 am

      I kinda hate Onodera but I think he is a very sensitive and fragile person that once it is broken it is hard to put back in pieces again.... so result, no confidence and bluntness when it comes to telling his feelings...

  13. Kanda Yuu March 9, 2015 5:52 am

    What happened with chiaki and hatori?

    March 8, 2015 10:48 pm

    Oh Onodera just hurry and Admit you loved Takano! I can't stand having to wait for more but....... I wnt to see more of it so I don't want it to end! WHAT IS WRONG WITH ME!

  15. loba March 3, 2015 10:18 pm

    Oh also i like how some times Takanos eyes look like cat eyes.

    This is about the fifth time i read this and there are some new chapters that weren't there before. Also noticed some that are no longer there. Still this manga is amazingly sweet and super adorable. I want onodera to tell takano HIS FEELINGS ALREADY FOR THE LOVE OF GOD! but i guess that means it would probably be over :(

  17. Akihito Ryuuichi February 23, 2015 9:28 am

    I like the manga, though i seen the anime first.. I like both... I hope the manga update soon and anime too go for season 3.. hehehe
    And onodera ritsu please give answer to Takano masamune as soon as possible.. Poor takano..

    • RoyalePhantom February 23, 2015 3:09 pm

      But if Ritsu gives his answer to Takano, then that means the manga will come to an end... The dilemma... ╥﹏╥

    • Akihito Ryuuichi February 23, 2015 3:50 pm

      Yes I guess so but i hope when the time ritsu tell takano he love him this manga not end and continue with they super lovey dovey couple..

    It's good that the manga was sorted. But have anyone else notice that Chiaki and Hatori stories is been taken out? I remember previously there was the story mentioned about Chiaki's assistant. This reload seems to have taken out. I've just re-read and saw the notice being taken out. Wanted to find back the notice but I can't find it already. ( ̄∇ ̄")

    • minkupinku February 22, 2015 11:10 am

      well their story is kinda... rapey in the light novel. it must've been because nakamura dropped the series already so the scanlators decided to remove it? (like you know, for people not to have high expectation ┑( ̄Д  ̄)┍ idk im just making guesses xD)

      it wasnt dropped by Nakamura. The scan group didnt like the fact of the "rape" in that side story so they didnt translate anything other then what they had before hand.

    • Rittie March 9, 2015 7:06 am

      Why does it matter if the scan group likes it or not? It's not like they are translating it for money or anything. It only happened once too, but hey, let's condamn the whole couple because of one time ._. (づ ̄ ³ ̄)づ
