From what I know, apparently it was initially released as short doujinshi. Physically, 6 doujinshi have been released so far whereas the digital version only has 4, hence "4 volumes on mang aka update". Then later on, they were repackaged into actual manga volume 1 (containing doujinshi 1-3) and volume 2 (4-6). Doujinshi 6 (the most recent) was released after volume 2 because Watanabe sensei wanted to redraw the panels.
Where can I find the raws? Do u have a lik?
They're in yaoiotaku
Yeah i checked the artists twitter and as far as i can understand the last chapter available is the last from volume 2 which is the sixth one, the artist is doing all the work alone so i think it will be a while before the next chapter is out, sadly :(
