That would be a strumpet. I said "crumpet".
It's an issue inherent in all adult games because it has become the nature of them that the MC is a babe magnet who attracts all girls to him, even ones who are not LIs and therefore don't have a path to an ending with them. Even when devs try to strike a balance by making it clear that the MC and a random side girl have no future together, players still push for it, just as they will sometimes push for girls who were never going to be with the MC to be with, i.e. KRJ.
In terms of "the most talked plot problem", I think it does relate to this very thing because a major issue was the fact that he wasn't the central figure in that moment. M&J both seem to forget he's there for a moment as they have their inexplicably and unbelievably quick reconciliation, and whilst these 2 were/are in a relationship, the MC perhaps should have been the central figure because not only was he the one to clear the air and try to bring them all together, but he was also the person they both developed feelings for and had their "affair" with.
For the MC to not feel central in that moment goes against conventional adult game storytelling, and sometimes it feels like this is what DPC is wanting to do, but it doesn't always seem to work for them. AL tried to do this too with the death of a LI and it proved highly controversial, even if DPC is still happy with that decision, but as much as they keep seemingly wanting to try and reinvent the wheel, I don't think most players want that. So DPC is walking a very fine line here between giving people what they want and pissing them off by subverting expectations and taking some of their agancy as a player away from them.
I've mentioned this before, but the HOT uniform is from a Daz asset called "

", and both the HOT name and colour scheme are part of that asset.
Also, Sage's HOT uniform in the Ep 5 flashback is from the "
