A real pity they got sick, but health is important, can only wish them to heal fully even if it takes a month.
This arc restarting out of nowhere solidify my belief that readers DIDN'T want this sudden flashback/gaiden arc in the climax of the moon church story, is totally unrelated and out of nowhere, nice, but it should have been only after the moon arc was completed.
The artstyle quality is different too, that makes me believe they had already completed this chapter and returned to the assault on MC shop/house only because the chinese readers rioted in the comic comment section.
So they released it now as the studio couldn't draw another one for illness and they had it ready.
I still don't understand why they did this sudden flashback, no one was asking for it, it was uneeded, it put in a hold a more interesting story (as we already know this 2 got together and no one died in that mountain, so the tension is low) and the novel already completed so isn't like they were working on the plot.
When I understand that editing a novel chapter for a comic adaptation isn't a walk in the park it feels weird that they used the manpower on this instead of that, unless the studio divided the effort, half made this flashback when the other half focused on the other arc.
...it just feels weird.
EDIT: I only realized later that the arc was a valentine special that focused on a couple, that does explain why the sudden jump, still don't like the weeks it took from the main story but I finally understand why it was done.
