Ok i played current upgrade. All is fine, but, i think that second prank story is kinda emotionally lacking. Im a sucker for redemption stories, and i think that ishido's scene does not have such an impact to actually emphatise to him.
I think it would be much stronger if instead of just relaying why he hates MC, he would actually jump him, crying and asking for how MC has all that ishido wants, while being basically a "nobody", after which there will be a catharsis moment and then you could choose to forgive him or humilate him.
