I will admit that this piqued my interest. What is her real motivation? What does she actually want to turn him into? What will be the moment when he breaks?
I think people approach this type of work with the wrong mindset, the appeal is to make the viewer uncomfortable, the morbid curiosity to see how far things go. It's not a work in which you should self-insert yourself as the protagonist, you have a thousand of feel-good power-fantasy isekai for that.
