I doubt it. This manga has being kind of cancelled because low sales. So I dont think she will be doing anything like this one in the future. A pity.
Well, according to the author said in twitter, vol. 4(final) will be released in July and extra contents are now on work. So probably there is a small chapter after ch23 in vol 4. Just guess and I hope so.(here is the source : https://twitter.com/yuhkikamatani/status/996702305012465664)
And I think the story is completed, it is not the question that being canceled. Just end in a too rush way.
Now you've gotten my hopes up
Aww man, i really don' t wanna this manga to end here. I hope there is still one or two afterword chapter after this one. To be honest, there is only two manga that i follow on this site that got me excited when ever it was updated, Harukaze No Entrager (Sequel to Umibe No Entrager) and Shimanami Tasagore. The first have a gay MC that was easy to relate and the latter have a good potrayaln of LGBT community as whole. With the first one on break fro 6 month and this manga ending, i need to probably search for another good manga with more realistic approach on gay character. I really hope Yuki sensei made another series about LGBT issue like this manga.
