Re-editing Notes:
Hello, J.B.Random here and I believe that I own an explanation as to why was “Beautiful Editor in Chief's Secret (02)” re-edited by me even through it was originally quite nicely edited by psyburn21.
Basically, initially I’ve decensored the second book about a year ago with its original editing intact, yet I got careless and did the job on a downscaled repack with 2048x1446 resolution instead of the original 3015x2128 version (something that only happens to me on rare occasions since I prefer to always work with the best scans available no matter how ridiculously big they might be). On top of this, except for a single old mildly-censored chapter from a different series, there were no other manga by Tatsunami Youtoku to peep on his uncensored art and learn from it in order to do a better decensoring.
Recently, after finally getting my hands on the scans of the first book, during preparations I was delighted to discover two new chapters of “Beautiful Editor in Chief's Secret” not long ago released in COMIC Magnum X almost with no censorship whatsoever. Those became a basis of my decensoring of the first book. Also, since it was not previously available in English, I had to edit it myself as well.
And just like this on one hand I ended up with the first book in high resolution, the best decensoring I could have possibly made and also edited in a certain style that I do, while on the other hand I had the second book in sub par resolution (due to my own mistake), suboptimal decensoring quality (due to past lack of the author’s art samples) and editing style that stood apart from what I recently did in the first book. Obviously I had to redo the second book from the ground and while doing so I just felt like I had to go all the way in all departments.
Please note that I’m not trying to denounce psyburn21’s original edit in no way, shape or form. It is still available on the Net both in its original version and with my initial decensoring from a year ago. This re-edit is meant not as a complete replacement, but as an alternative version.

That last one where she in a bride outfit not chapter 5 the one with the question mark is that the final chapter? anyways thank you this has been hot af.

Beautiful Editor-in-Chief's Secret (1) consists of two chapters:
--- Beautiful Editor-in-Chief's Day Off
--- Beautiful Editor-in-Chief's Secret Report

Beautiful Editor-in-Chief's Secret (2) consists of other two chapters:
--- Beautiful Editor-in-Chief's Secret Overtime
--- Beautiful Editor-in-Chief's Secret Encouragement

And then there are those two chapters on top:
--- Beautiful Editor-in-Chief's Bridal Pose
--- Beautiful Editor-in-Chief's Bondage

So that makes Bridal Pose the fifth chapter as far as my countdown goes.
When you say "the one with the question mark", do you mean this picture? /g-hentai/?s=504144a671/897882-21
As of now that is just an artwork that has been bundled with the Bride chapter, also it has both bridal and bondage themes at the same time going on with it, so my guess is that it will be the cover to Beautiful Editor-in-Chief's Secret (3) bundle book when (if) it will be released.

@qberg That image is the cover of COMIC Magnum X Vol. 22. I included it in the translated version since it depicts the character from that story. He was paid to draw a cover for the magazine, there's no special meaning for it beyond that.

@Dynellen
Beautiful Editor-in-Chief's Secret (3) cover might end up being something else entirely of cause, but that picture just fits really good so I've used is as a probable cover of the probable book in my Series History Notes. I've put a giant question mark all over it as a sign of probability as opposed to certainty.
In the end of the day Tatsunami Youtoku might decide not to publish any kind of two-chapters-long Beautiful Editor-in-Chief's Secret (3) at all this time, who knows.
