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.

      There are actually several novels, though I'm not sure they'll appear in the manga much more (though I think there's a Yokogawa chapter coming in a few months, if it isn't another novel).

    Anyone knows if theres a continuation of Ypkozawa no baai novels? The last one I read was if i remember correctly, a girl from Kirishima's highschool who's now a writer tried to work with him by making him the producer of her work in manga form so she can flirt with him but kirishima saw through it and plainly declined.. is there a continuation? And also a producer found out about yokozawa and kirishimas relationship in one look...

    I just wish we can finish Takano and Onedera's story. I'm getting impatient and bored. The side couples arent interesting at all. The only side couples that are interesting are Asahina/Isaka and Kirishima/Yokozowa, both of which have their own uninterrupted stories. I really feel that sensei is just dragging this out for no good reason. I quit reading Junjou Romantica for the same reason, though I didnt like it that much to begin with.

    • Catnip
      July 28, 2016 4:30 pm

      Well, I can understand why you're impatient and bored and I think you're not the only one thinking like that. But you know, it's kind of the mangaka's thing... so if you're bored then you shouldn't continue reading b/c it seems this manga isn't going to end soon.
      Personnally, I like Sekaiichi Hatsukoi. I just love Takano and Ritsu and even though Ritsu hasn't confessed yet, there's been some development in the latest chapters and I just can't wait for the next one ^_^ but well, once again, I understand why you and some other people are bored with this story.

      Yea, I know. I've read some of her other works as well. I actually prefer the shorter ones because they don't drag on. I've been trying to drop this, but can't find it in me to do so, because I really like the main story and I need to see Onodera and Takano's happy end. And yes I see the development too, and I'm loving it <3

    • Sallie August 1, 2016 11:06 am

      I skipped over Takano and Onedera's story, I ran out of patience as well. How many time or how much can Takano shows and tells Onedera's how he feels toward him, in my opinion either Onedera's is an idiot or just really slow.

      Ritsu would have confessed long ago if Takano listened to him. Ritsu often told him he wanted to do things in the proper order and what did Takano do ? He jumped on him.
      And just so you know, they're TWO in this relationship. So it means they're BOTH at fault. Yes, Ritsu is too stubborn and can sometimes be annoying but Takano is also at fault.
      Besides, people puts way too much pression on Ritsu, be it Takano or his mother. People are too harsh on him.

      i agree. its the same thing over and over. takano or ritsu get jealous and have makeup sex. ritsu telling everyone ELSE that he loves takano, but doesnt tell him. i know he tried telling him a couple of times, but thats no excuse to tell him again until he listens. thats the same as people saying they wont admit to cheating because they arent given a chance. if you really want ot say something, you will make sure to say it.
