Curate, connect, and discover
Sort of morbid au idea but what if system points were like health points. They already are pretty close since hitting zero means death. Though my thought process was more like sqq and sqh would take physical damage if they got point deductions. The amount of said physical damage depending on how many points they loss. I don't think that it would count actually health in the matter, like if either of them took non system damage it wouldn't effect their points (same way around for healing). Though to give them some slack I think they'd only be effected by loss of normal points, not b-points or protag satisfaction.
This could either start from the very beginning or this could be implemented because the system thinks that sqq and sqh are too lenient with their point loss (or just their behavior in general). Either way I think it would be horrifying (more than the whole 'drop to zero points and you essentially die') and very angsty. It would also make it a lot harder to hide the transmigration.
