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.

    I WANT UPDATE *DROWNING IN MY TEARS*

  2. Cecilia July 27, 2015 11:29 am

    Don't worry Takano-san, I know that the day will come when Ritsu will finally confess his love for you. Just don't give up okay? ^_^ Gosh, I really miss takano and ritsu. ヾ(❀╹◡╹)ノ~

    July 25, 2015 7:44 pm

    that something terrible will happen after the countdown and Ritsu's confession will be nearly too late.

    Does anybody know if there will be a third season like "Junjou Romantica"?

    I read it.
    And now Kirishima x Yokozawa pair has won over me. It was Takano x Onodera, but after read the novel I got the urge wanting to hv the novel. But, can't since it's not sold at my country.

    Bout the story, I kind of panick and irritating when a woman came into this pair relationship, making people talked bout marriage.

  6. B July 24, 2015 8:06 am

    When is the next update ?

  7. lightrocks July 22, 2015 5:34 pm

    its getting soooo slow with the countdown soon the thing will go in between updates saying "only .1245454284245 fractions of a day until onodera falls in love" like PLEASE

  8. Esu July 18, 2015 6:00 pm

    I want more of Ritsu/Takano ....

  9. yay July 18, 2015 5:51 pm

    I tried third time. I failed....I hate it ;)

    Even though they're technically in the same universe, I much much prefer the romance in this manga compared to Junjou Romantica

  13. Cecilia July 7, 2015 3:39 pm

    I wonder when will Onodera confess to Takano. (づ ̄ ³ ̄)づ

  14. keo July 7, 2015 10:42 am

    Is it me or is that freaking evil stupid countdown timer thing in onadera's story line slowing down? I REALLY REALLY want to see what happens when it hits zero

    • A July 8, 2015 11:05 pm

      I melt a little every time I see how much closer he is to falling in love. :) Can't wait for it to hit zero, but enjoying the journey.

    Guys, I have a question. What are your favorite parts/moments in this manga? ヾ(❀╹◡╹)ノ~

    • KawaiiKiller July 5, 2015 10:25 pm

      When Takano told Onodera he wouldn'r be able to move on if Onodera suddenly moved again or if they are separated. I even took some screenshots

      ah yeah, I remember that. right in the feels

    • Asuka Hana July 10, 2015 4:40 pm

      My favourite onodera X takano parts are all the time they had sex. That was just so sexy.. ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
      In tori X yoshino was when yoshino got tori drunk that was just hilarious (≧∀≦)...
      And in kisa X yukina my favourite moment was when yukina kissed kisa during the fashion show. And favourite part was the entire chapter when yukina was stuck in a rut with painting.. And one night with kisa changes all that.

    • Estrella July 10, 2015 5:40 pm

      When Onodera got sick and Takano went into over protective mode. Also, when ever Takano get's jealous when his ex-co worker is near Onodera.

      Yeah me too, it's every time TakanoxOnodera are having sex, it's soo cute. They are not "really" together but they're having sex like crazy, Takano san can't stop pushing down Onodera who can never resist. (づ ̄ ³ ̄)づ I want more of them !!!! The other couples are great too !!!

    • Anonymous July 15, 2015 1:15 pm

      When they always have a romantic moments onodera and takano!! Kyaaaaa

    • NoLife-Artist5 July 16, 2015 8:49 pm

      When onodera kisses takanos hand and TRIES to confess and when onodera was sick with takano taking care of him (●'◡'●)ノ

    • hataki July 17, 2015 3:23 pm

      i think i like when onodera collapsed, and takano laughed that he was still following behind him. that he didn't need to cause he'd always be there for him. then ritsu was adorable and held him back. then they had their fun and i love takano's cute cuddle him and kiss his head moment! that one's my favorite.
      with chiaki and tori it's probably tori drunk, that was sweet as hell.
      and as for kisa and yukina, probably the kiss at the fashion show. that was just awesome.

    • Ao.May

      At the stopped train, no electricity, Takano kissed Onodera. Or when Takano piggyback Onodera (I only remember that this one is from Takano's case). Those two moments are really sweet that chocolate melt even before I put it in my mouth!

    I'm not sure if this is just me but the style of the manga looks different(drawings). I really liked it before. Also JUST CONFESS ALREADY ONODERA!!! ヽ(`Д´)ノ

    OMG!! Funimation just announced it's going to be airing JUNJOU ROMANTICA SEASON 3!!!

    So the only guys who wanted to translate JR and SH just said that he is not going to permit download anymore... gyaaaaaaahhhh now the result for sharing things without permission, we are all screwed

    • Natsu June 20, 2015 4:41 pm

      That's toooooooo bad!!!! ╥﹏╥

    • Anonymous June 23, 2015 7:40 pm

      Sad about JR. SIH we'll get eventually. One person messed it up for all, but they probably wanted to for fun.

  19. KuudereSama June 17, 2015 6:52 pm

    • Riichan June 22, 2015 2:31 pm

      In all honesty, I like all the pairings. Maybe out of all of them, Hatori and Chiaki is the one I'm not into the most, but I still really like them too.

    • ChucklesTheMime June 22, 2015 9:27 pm

      I do not like Hatori and Yoshino. ...rather, it is Yoshino that annoys me. He is dense as heck. I cannot even. I love Hatori though. I almost want Yuu and Hatori to end up together at this point.

    • sodiumchloride June 27, 2015 7:51 pm

      i dont like kisa and yukina either. yukina is reallly cute but kisa acting like an idiot time to time -.-

      July 18, 2015 4:08 pm

      It's Hatori and Yoshino.
      I love Hatori (somehow he reminds me of Asahina) but his partner, Yoshino, I don't like him. His dense is waaaay too over than Misaki or Onodera.
