Even it may not be the case, I used to like to think the light effect on the training stats overweight their real feelings, as the more training goes, the actual feelings in them is just trapped and overpowered by the light training, so when you use the pink light on Ward the first time, the light is actually stay on her subconcious and can "give" Wards an interest to be the Mc's lover, or an orange light that can give or strengthen Ward's Kink on being used, or other's like incest, exhibitionism and stuff..
It's like when you install another antivirus on your PC, you can't use your Windows defender as long you have the new installed av software.. So even She actually disgusted by us, the light trainig and the given feeling is just simply stronger than her original thought, and She can't help it. Again, it's just how I used to like to think
But since there's an editor mod you could always edit the stats yourself to make it any less weird, I make an adjusment using the Editor when they like me enough I'll adjust the disgust level to a lust. Or when I think the dad's level 2 love on my save is too high, I reduce the value to 1 just so it can felt right..
A bit of a hassle yes, but it helps to make the game better in My case.
