Summary

Sick of feeling like he’s riding on his parents’ coattails, Onodera Ritsu quits his father’s publishing company (where he was a literature editor) and gets a job at Marukawa Publishing--only he ends up getting stuck in the crazy shoujo manga department, which happens to be populated entirely by male editors. Plus--the editor-in-chief happens to be none other than his old flame from high school!
Also included among the various volumes are storylines following two of Ritsu’s fellow editors: Hatori and his longtime friend (and mangaka he’s in charge of) Chiaki, as well as Kisa and the attractive bookstore employee he has his eye on, Yukina. An extra novel follows salesman and longtime friend of Takano’s, Yokozawa, as he’s swept off his feet following a harsh breakup by attractive widower and single father Kirishima.
This series is loosely connected to Junjou Romantica (by the same author), as characters such as Usami Akihiko and Sumi Ryouichi are mentioned a few times as authors, and Isaka Ryuichirou is a recurring character. Yokozawa's partner, Kirishima, also shows up as Takahashi Misaki's boss in Junjou Romantica. Trying to spot the connections is an adventure of its own!

    why there are still no update of this manga?

    • Lightasus August 22, 2014 5:17 am

      September Scanlation dropped it since it recently got licensed. We'll probably get some updates anyway when someone will want to take their time to do it, but it could take a while. The scanlation teams won't touch it though.

  4. Help August 21, 2014 5:25 am

    What chapter was that when they have sex in the shower and tAkano passed out coz hes too tired?

  5. Glass Heart August 20, 2014 4:56 pm

    The only hope that this can get transalated is that a freelancer will translate it.. not a scanlation group. Don't care if its not perfect grammar. I saw some license manga being translated because of those people. Though they are not fast and slow(maybe quite messy) but its better than nothing

  6. Gaa August 20, 2014 12:53 pm

    This has been licensed?? Noooo. This manga will never be available in my country. *uglysobs
    Goodbye SIH... Nice to know you.

    I hope scanlators will still translate.. But i think thats impossible now.

    • Anonymous August 20, 2014 4:50 pm

      Its that really really true....???

    • Lightasus August 20, 2014 4:58 pm

      Well, while big scanlations teams won't touch it, maybe someone will want to scanlate it. It usually means chinese scans, not so good cleaning, slow updates, a person or 2 translating and type-setting, maybe not so good translation (sometimes done from the chinese translation). We could get lucky and get great ones anyway, but it's usually like that. Junjou Romantica is licensed, and we still get updates, though they're not as good as they could be if a big scanlation team like September Scanlations was doing it. Though it probably won't bother you that much if you can't buy them, it's better than nothing and the job is usually okay.

    • Anonymous August 20, 2014 5:09 pm

      Is that so thanks for the info...but idk if the book is available in Malaysia...
      But probably I can buy it online.

      Volume 1 is not even out yet though. I usually buy my stuff on Amazon, not sure if in your country it works well for mangas. But I'm pretty sure you'll be able to find them online anyway. If not, I made a little google search and found that the Kinokuniya Bookstore in Kuala Lumpur apparently sells yaoi. Maybe it's not too far from where you live, you could check it out.

    • Lightasus August 20, 2014 5:26 pm

      Amazon says volume 1 is going to come out in english on February 10, 2015.

    • Anonymous August 20, 2014 6:51 pm

      Thank you so much maybe I'll try that....><
      Well it way too far believe me its took about 8 hours to get there...TT^TT

    • Lightasus August 22, 2014 5:44 am

      Aww, don't be sad :)
      Well, they have an online bookstore:
      http://www.kinokuniya.com/my/
      Bookdepository ships for free worldwide:
      http://www.bookdepository.com/
      So I think you'll be able to get them online without too much trouble. Last one would be amazon, but the shipping rates are pretty steep and I'm really not sure you can get free shipping for Malaysia. So just make sure you get it quick, since yaois can be a hassle to find after a certain period of time.

    • Anonymous August 22, 2014 7:42 am

      Thanks but Idk don't really know how to ship stuff from overseas and I'm also not really good with purchasing item online too cause I've never try buying anything online before so this time I wanna try for something I definitely fond of....

      i know right. i've tried once to search the book in kinokuniya, it's like trying to find a needle in a haystack(well, since japanese isn't my language). I gave up.. i'm collecting money now to buy it from ebay.. so i got that going for me, which is nice..

    i totaly liked it when he said '' wow what a dick '' lol

  12. Hotaru22 August 11, 2014 5:19 am

    HAHA You know when Onodera told Takano that he thought that Takano was just messing with his feelings and toying with him? At first, I thought he was just being paranoid (about a little laugh) but after reading this... http://www.mangago.com/read-manga/sekaiichi_hatsukoi/mf/v06/c001/26/ ...it made more sense.

    • Anon August 11, 2014 5:57 am

      Haha, Takano dug his own grave, because of his ambiguous gestures/actions when they were teens, no wonder why Onodera in the present is jaded.

    • hersheycoco August 16, 2014 8:23 pm

      Lol exactly! But I would get over it since he's so sweet to Ritsu now except when he messes with him at work :3

  13. K August 11, 2014 2:28 am

    As many noticed, "The case of Yokozawa Takafumi #4" is only an extra here... but I found it on animea.net. xD
    And just a heads up: don't use the arrows or the "back" and "next" buttons, because they lead to a "image not found" page. If you select the page number on the list, everything works out fine.

  15. TAKAYO August 10, 2014 4:52 am

    i really hope this SIH manga will update as usual as the Okane ga nai and you are my loveprize in viewfinder because they all are licensed but still update!

    • TAKAYO August 10, 2014 4:52 am

      so hope!!!~~~~~

    • TAKAYO August 10, 2014 4:53 am

      but due they are licensed maybe slow updating will occur

    • Anon August 11, 2014 5:59 am

      I hope so, bc I like SIH slightly more than JR

  16. Delilah August 9, 2014 11:23 am

    So, the scanlation group has dropped this manga since is eventually licensed in English!
    I'm going to miss it, oh my... T_T

    • Unyanyanyan August 9, 2014 3:01 pm

      E? Really? T^T

      I hope they'll give us summary like they did with no.6 before...

      Because I really want to know what will happen next and waiting for the publisher to catch up with all volumes definitely will take a long time~

  17. Anonymous August 8, 2014 8:10 am

    Ok so I'm going to write this because it has bothered me for a long time and I'm kind of fed up with it (I'm not trying to be mean, just stating my opinion on something that I have noticed in this fandom).

    There are just so MANY people who feel bad for Masamune and talk about how much he suffered because of their break up and how he started drinking, etc. because that's what we were told in the manga. But almost none of those fans stop for a minute to understand Ritsu's feelings or try to read between the lines. Just because it wasn't mentioned in the manga that, or how much Ritsu suffered from their break up, doesn't mean that he didn't have a hard time. I don't want to sound annoying or like one of those fangirls who over-interpret everything, but has really no one noticed Ritsu's issues? I'm not saying that Takano didn't suffer or that it was easier for him, but I get the feeling (not only with this manga) that some fans favour the semes because they're "more their type" (since they are often a little bit more manly looking or whatever). Ritsu even mentioned that his character changed because the break up hurt him that much and some of the things people complain about are actually signs of depression or anxiety (such as his shyness, anticipating the worst or stomach pains! ). Now, I'm not saying that Ritsu is definetly depressed or something, but he is under a lot of pressure and really insecure. I hope that at one point we can read a chapter where he and Takano are happy and where he is more comfortable about his feelings or sex, but I don't think he will ever be the one to really initiate sex. It doesn't fit his character. Most Ukes in Nakamura's mangas are that way, aside from a few exceptions, but if you guys like more agressive ukes, and I like that, too, there are a lot of mangas that are that way.
    I'm not saying that you're not allowed to feel this way or anything like that, but try to understand Ritsu some more.
    I'm not sure if my reply wholly fits the topic of this thread, but it's something that I have thought about quite a while and I thought I would just voice my opinion.
    Regardless, I hope that we will be able to read more fantastic chapters of this manga and that it will all turn out well in the end.

    • Anonymous August 8, 2014 8:22 am

      i know right i actually notice the ukes more cause im a girl and they are more in my position . . . u know. . .

    • marry August 8, 2014 11:43 am

      for me it doesn't really matter if he suffered or not because he brought it upon himself so it seems well deserved. He was the one who assumed they had broken up and instead of talking about it he went aboard and cut himself from love (which does indicate that he suffered a heart break or else why promise yourself you will never fall in love again)
      I am more sympathetic towards the seme (can't remember his name) because he is more blameless in the conclusion of a simple mis-wording. from his point of view the lover he had been dating and had deep feelings for disappeared on him with out saying a word, i mean how would you feel if you were in the same situation?

    • Morcheeba August 8, 2014 12:51 pm

      Everyone in the "Maiden Department" needs to see a shrink on a regular basis, but Onodera and Takano take the biscuit. Well aside from the fact that it wouldn't be as interesting if they weren't like that, they've both had communication issues from the start.
      Come on, Onodera dated him without giving him his real name. (Did someone call for a space cadet? But Onoderas face was priceless when it dawned upon him) Takano indulged in his misanthropy and waited far beyond the last possible moment to express his feelings. Clumsy doesn't even describe it.
      In my humble opinion there's no winner at all between those two: they both made awful choices with the purest reasoning and ended up scarred, scared and dependent (though they sure can make a huge brawl out of this).
      If they just up and confessed to each other with rainbow puking unicorns and the whole rosegarden blooming, the earth might change it's torque - so NO I wasn't surprised about the heavenly intervention when Onodera lost his composure (does he even possess something like that?!)

      I look at both sides their so e king on past issues even if they're not together. Mainly one of them is communication which both parties lack in. Severely. Their both dealing with personal problems that's going to catch up to them later. That's why I feel onodenera is trying to take it slow, he wants to improve himself before going into a relationship but luckily Takano helps him a lot with that :3 I just rewatched some episodes and it was soooo cute. Onodenera was so innocent back in the day and Takano such a brat. I'm totally joking when I say this but karma takano for being a little mean to him back in the day. So as I said before both have issues but Onodenera's are still present to him and Takano will effect what he chooses to do with his life/career. I need to see Onodenera's parents but we'll probably see them close to the day Ritsu falls deeper in love or confesses to Takano. I can feel it. But anyways I like Onodenera's a little more than Takano because he's adorable and sometimes an idiot but whatever.

    • Emye August 17, 2014 10:54 pm

      Haha, I literally just saw this comment and I have been on here a couple of times before. I actually favor Ritsu over Takano, because I was in a similar situation. I know that the majority of fans will favor Takano, but I normally favor the character I relate to. :) I totally agree with your ideas and they present valid points with both characters' past.

    • Evilcleo August 18, 2014 6:04 pm

      I'm more for ritsu myself. He wasn't innocent in their communication issues but takano was a real jerk and acted like he didn't care. Isn't everyone saying in yaoi they'd prefer if the uke didn't pick the jerk? Well, there you go. It happened.

    • anon August 19, 2014 2:52 am

      Takano originally dated Ritsu to crush his 'ideal' world;, he wanted to toy with Ritsu. So in some ways he deserves this backlash. I'm not saying that Ritsu is all in the clear either, but I feel like Takano is slightly more at fault. I just love their bickering. :D

  18. itoshi August 7, 2014 7:40 pm

    before, septembre scanlation said that they don't do hatori x chiaki chapters then sure there's non tranlated ones, do you know where can i find them
