if I'm not mistaken this is because, as time went on and the chapters got compiled into volumes, the resulting chapters ended up being bigger than originally released, which someone for some reason decided to update on the site as well.And the trend continues of the comments having nothing to do with what's in the chapter right now, which is a discussion between adults about figuring out how to afford a property that's about to be available, and refusing to let the kids that would totally get carried away hear about it. Because you know both Hina and Rei would totally do that. That depiction seemed so spot-on.
