This honestly feels like a short project, nothing in the domain of Kaguya lengths of planning ahead, me thinks.
We only have 4 MCs with already established relations between each of them. Knowing aka, I think he might just wanna go for a 10 volume 100 chapter or so run, then start up a new project.
The side cast is kinda bubbly and wholesome tho, like the manga club, Seki's friends or even the love agency tenchou. I doubt most them will actually get an entire arc for themselves, and we already kinda shipped off the manga club girl with her childhood friend as well.
