When I googled if it was canceled I got :
No, the manhwa (Korean comic) It Was a Mistake, Grand Duke! has not been officially cancelled. It is currently on an extended indefinite hiatus due to the artist's health issues and the need for back treatment.
But doesn't that "indefinite hiatus" mean forever?
That is wat I found on google. You can look it up too it might say something different
no it just means that they dont know when itll come off hiatus. it might be years or it might be a few months- just a way of saying they have no idea how long itll last but expect it to be awhile :/
It's been years since any updates.(〜￣△￣)〜 And the rumor mill says this was discontinued.
Does anyone know if this is true? ╥﹏╥
