Not sure about that, since there is no normal situation in the game where you can play after an Hscene, apart from the Incufly and the Basilisk capture scene, both of which I suspect have their own custom code to handle it. Imo, you should probably investigate the Incufly and try to figure out why this one lets you play again (it might be that it's just hardcoded to the Hscene of the Incufly).
I don't know if this will do anything, I checked what changes the value in raped, because when a regular enemy, not Incufly, goes, his raped goes from 0 to 1 and doesn't change to 0 until the game over and loading the save, but for Incufly it changes if there is enough health, from 0 to 1 and then to 0.
This is what changes after the HP is removed after the scene with Incufly

in the value in memory view they both have 0, after the scene is played the scene does not change or I just did not see it, but it is used. Perhaps something from this after checking whether there is health to continue the game removes 1 and puts 0 and removes the scene
