Kumo's chapters in the WN were my favourite and I treated the Hero chapters like a child treats green pepper. I'm a good child so I ate them up, too. I know that both storylines will intersect, that a lot happened in the Heros stories and therefore, that there will be a lot stuff to catch up with by that time. My worst fear is, that the mangaka might drop Kumo-chans story for a year or even more and concentrate on the slightly generic and therefore rather boring isekai stories of the others, that were in that classroom. Or the mangaka might try a 1:5 mixture in updates. At this point it's sadly too late for a 5:1 mixture.
