I understand this is a fetish manga but I think it would make more sense to make a spin-off to contain all these side stories while leaving the main story to the MC and see what girl wins the bowl (or even just give it an open ending or harem ending, whatever). It just feels weird all this jumping around side-jobs without seeing any of the main girls. I think everyone here grew attached to some of the girls and now they are basically forgotten in the void.
