Having read through all the chapters and looked between the results,there's no reason at all for Office Lady Officers to be given any sort of defence,because they are simply taking too long whilst the other two have completed the series two months ago with no discernalable difference in quality.
You can try to call it "sniping" but they completed the series with no badly translated issues,have stirred no one else regarding the matter,and even talked to each other with cordial results,and not a single missed chapter in the 19 chapters that will quite literally take a year plus for the other group to do.
We're here to read comics,and if the comic is there with the quality that so many of y'all demand,then why on Earth are you debating 'bout it?,go finish reading the story and move onto the next.
