Need help about manga title.

I just remember about a note from author in some chapter. Still ongoing. If not wrong when i read the translated chapter just around 10 - 20 chapter.

It say that volume 1 no longer have printed version. It will only sell on digital so the bonus on volume 1 printed version will not be included.

And i remember when i see this note i search on mangaupdate that it has official english licensed.

Do you remember what the manga was about?
