It just depends on how corrupt she is I imagine. I believe a telltale sign is when she's sleeping with the NTRist, her posture may identify what ending you're about to get if you end the game, as she has 4 different postures while sleeping with the NTRist depending on how corrupt she is. But that's just a theory.
You'd have to extract the game files and then open the game up with an MVproject file while also having RPGMakerMV installed; playtesting it should enable a debug menu of sorts on most H games in RPGmakerMV where you can activate common event switches from said menu.
